2015 was an incredible year to be a web developer, and great year to bebuilding an Ember app.Ember 2.0 landed in August, and with it came the first major shift inapplication architecture since Ember left its SproutCore roots. The Ember-CLIteam made massive improvements to the speed and quality of our build toolingseveral times over, all while continuing to be the foundation for a growingaddon community now topping 2000 projects. Ember-Data stabilized its publicAPI for the first time in the project's history, and continues to contendfor the title of most complete client-side JavaScript data layer.Other projects, under the official umbrella and outside it, continue toinnovate and mature.With 2015 in the rear-view mirror, we should take a moment to check our assumptionsabout who is in the Ember community and how they work with the framework.To that end, we're pleased to announcethe official 2016 Ember Community Survey! Survey Landing PageCompleting the survey should take about fifteen min

The past year has been a great time to work with the web, and an exciting one tobe building applications with Ember.Ember.js completed eight backward-compatible minor version releases in thelast year, 2.4 through 2.11.Included were the framework's first two Long-Term Support (LTS) releases.Glimmer 2,a major rewrite of Ember's rendering system, landed in Ember.js 2.10.Framework support for Ember Engines landed inin Ember.js 2.8.Support for Ember FastBoot stabilized inEmber.js 2.4.The Ember.js addon community grew from 2,000to over 3,500 publicly available addons!With 2017 already under way, we would like your help to learnabout who is in the Ember community and how they work with the framework.To that end, we're pleased to announce the official 2017 Ember Community Survey. Survey Landing PageThis is our third year learning about the community's makeup and interests,and we're looking forward tosharing the results at EmberConf 2017 on March 28th.The number of survey participants grew from

The last year has been a wonderful time to work with the web, and a thrilling one tobe building applications with Ember.Ember.js completed seven backward-compatible minor version releases in thelast year: 2.12 through 2.18.Included were three Long-Term Support (LTS) releases.Version 2.18 was declared as an LTS and is the final release of the project's 2.x series.Ember 3.0 and 3.1 beta versions also came into existence, marking the beginning of the 3.xseries.3.0 removes public API deprecated in Ember 2.x releases.Ember FastBoot, a server-side rendering solution for Ember apps, reached 1.0.The Glimmer VM,Ember's rendering system, also experienced a lot progress. This includesimplementations of <Capital />-style component syntax, compiled binarybyte-code, incremental rendering, and SSR with incremental rehydration. The October Glimmer Progress Report is a good place to look for details.The Ember.js addon community grew from 3500to almost 4500 publicly available addons!With 2018 already un

The purpose of the Ember Roadmap process is to rally the community around a number of shared goals. This post documents those goals for 2020.Since the Ember community cannot predict the future, we cannot be sure that we will achieve all of the individual items enumerated here. Instead, the purpose of this document is to give the community a common purpose to aspire towards.This year our two headline priorities are:Polish the practical and conceptual details of Octane (tracked properties, Glimmer components, related tooling, accessibility, performance and payload improvements).Make Ember easier to try and adopt, but also lower barriers for Ember developers when collaborating with the greater JavaScript project. We will do this through improvements and simplifications to the framework, and through focused communication with the greater JavaScript community.This document was started in fall 2019. It is a distillation of multiple sources:The 2019 Community Survey.Community #EmberJS2019 blo

Back in March, an Accessibility (A11y) Strike Team was formed to address the issues outlined in Ember RFC Issue 595 - Technical Accessibility Issues in New Ember Apps. This blog post is to update the community on that group's work.The Strike Team met weekly between March 25 and June 24. We even managed to celebrate Global Accessibility Awareness Day!There were five items listed in Issue 595:Application Language SupportLabel/Input SupportPage Title SupportSupport for ...attributesAccessible Routing SupportActive WorkApplication Language SupportThe goal of application language support was to provide a mechanism for new Ember apps to pass WCAG Success Criteria 3.1.1 - Language of Page. To meet that goal, Joseph Sumner, Jamie White, Ava Wroten and Melanie Sumner authored RFC 635, which proposed a --lang flag for ember-cli. This flag would enable developers to declare the application's language while they were creating the app, allowing them to more easily meet this particular success crite

Currently, Ember uses release channelsto help users balance between a desire for new features (canary or betachannels) with stability (the release channel). While semver guarantees meanthat upgrades are quite straightforward, some users aren't able to upgradeevery six weeks. To address these needs,we are announcing a new LTS releasechannel.Ember 2.4 will be the first LTS release of the core framework, and willcontinue every four releases thereafter. Additionally, we've updated theemberjs.com/builds page with better guidanceabout when and how to use each of the channels.For our users, LTS releases allow you to upgrade less frequently while stillgetting support from the Ember project and the wider ecosystem.For addon authors, LTS releases allow you to know which versions of Ember tofocus effort on.As a project, Ember will provide security and critical bugfixes for the mostrecent LTS release, in addition to the most recent release (as we do today).We will also avoid breaking heavily used

As of [email protected], Ember is shipping a public preview of our official TypeScript support for the framework itself. This is the next step in implementing RFC 0724: Official TypeScript Support and RFC 0800: TypeScript Adoption Plan. Anyone using TypeScript with Ember 4.8.0 Beta 2 or later can opt into using these preview types by removing the corresponding @types packages and adding the following import in your types/<your app>/index.d.ts file:import 'ember-source/types';import 'ember-source/types/preview';This will set your app up to start using Ember's preview types now and to automatically benefit as we stabilize our types incrementally over the releases ahead. You won't have to do anything except add these once and then upgrade your app on your normal upgrade cadence!Note that there are some significant changes to these types compared to the types as they exist on DefinitelyTyped today. All public API remains supported, but in line with RFC 0800, we intentionally provid

We know that building your apps on top of a framework requirestrust, and that trust is never put to the test more than when securityvulnerabilities are discovered.While we're very fortunate to work on an open source project that runsin a sandboxed environment, the browser, we realize that even JavaScriptapplications can be vulnerable to attacks from malicious third-parties.Ember.js is designed to mitigate common forms of attack. For example,all values rendered using Handlebars are automatically escaped toprevent XSS attacks, and developers must explicitly opt in to outputtingraw HTML.To ensure that Ember applications stay safe, today we're announcing theEmber.js Security Policy, to help security researchers anddevelopers responsibly disclose potential vulnerabilities in Ember andEmber Data.We have also set up the Ember.js security announcements mailinglist. This isan extremely low-traffic mailing list reserved solely for announcingsecurity releases of the framework. If you're deploying

In this year's EmberConf keynote, Yehuda mentioned that we are working on a highly optimized rendering engine for Ember called Glimmer 2.On behalf of all the contributors who have lent a hand along the way, I am very excited to announce that we have released Ember 2.9.0-alpha.1, the first official build with Glimmer 2 included.🔑 A Key Milestone 🔑During the alpha testing period, we will publish new alpha builds on a weekly cadence, following the beta releases schedule. The alpha releases will be cut from the master branch, but with all experimental features other than ember-glimmer stripped from the builds.The purpose of the alpha releases is to enable our community – especially the addon and tooling ecosystem – to start testing the new engine for compatibility and offer feedback. Needless to say, the alpha releases are not intended for production use.To test your apps with the alpha builds, run bower install --save ember#alpha and follow the prompt to persist the resolution.From Embe...

We're a few weeks away from the release of Ember 1.13 and Ember 2.0 beta, and while there's been a lot of focus on those releases, the trains will keep rolling on June 12. There will be a 2.1 release 6 weeks hence, and a 2.2 release 6 weeks later.With all of the focus on Ember 2.0, it's easy to forget that 2.0 is just a six-week release, with the added ability to remove some built-up cruft. Because of the symbolic nature of 2.0, discussions about the future have had an artificial end date of June 12, which is now three weeks away.This post gives some more details about what cruft will be removed in Ember 2.0 and, since the first features in Ember 2.1 will land in three weeks, what we plan to do in the early releases of Ember 2.x.It's important to note that we've talked a lot about an improved "Ember 2 programming model" over the past several months, significantly inspired by React. While much of the model will be in place in Ember 2.0, the early releases of Ember 2.x (especially 2.1 an

The baseURL configuration option and the accompanying <base> tag in Ember CLI applications are often and tragically misunderstood. There have been at least 67 issues opened for Ember CLI referencing baseURL, making it one of the most common points of discussion. As a result, in Ember CLI's canary channel, we have deprecated baseURL and removed the default <base> inside of index.html. The intent is that this change will be released with Ember CLI 2.7 stable in roughly 10 weeks.Existing applications are able to continue using baseURL with a deprecation warning. If you are eager to adopt this change, you should note that the removal of the <base> tag may impact how your application is deployed, and if so, will likely require some small migration effort, detailed below.This is the culmination of a lot of research and work by Tobias Bieniek and we're incredibly grateful for his efforts.What was it?baseURL allowed an Ember application and assets to be deployed to a subdirectory without requi

If you've been following along, the Ember issues tracker has grown to over 200 active issues. While this is better than some other large OSS projects, it's still too large for us on the core team to easily keep track of. There are also a number of issues that are over six months old and even a year or two old.Declaring straight-up issue bankruptcy is appealing, but does a disservice to everyone involved. There's a lot of useful information here for the core team and many of these issues are things we are actively working on solving. So we're attempting to cut down on the number of issues in a bit more targeted way.In many cases these old issues stuck around because the solution was non-trivial and only a limited set of contributors was qualified to fix them. In some instances, a fix involves considerable internal refactoring that no one has yet had time to do and was hard to justify for one fix.To help keep things manageable, we'll be consolidating these types of issues into single met

(This post was originally published on www.pzuraq.com)If you've been paying attention in Ember lately you may have heard the term "Octane" floating around here and there recently, and wondered what all the excitement was about. It may seem like a bit of a big deal - and that's because it kind of is! It's Ember's first new edition, proposed in the Ember 2018 Roadmap, and represents a major shift in the mental model behind Ember.js and Ember applications. In this series, I'll be diving into some of the new features that are part of Octane (specifically the ones that are part of the browser side of the framework) and giving a brief overview of how the feature works, and why the feature is being added. The features I'm planning on discussing are:Native Classes (+Decorators)Angle Bracket Syntax & Named ArgumentsTracked PropertiesModifiersGlimmer ComponentsThere are more features that are part of Octane, such as Ember's new file system layout (also known as Module Unification), template impo

We are thrilled to announce that we will be adding to the spring excitementsurrounding Ember Octaneand EmberConf 2019 with the release of the fifthannual Ember Community Survey, and as always, we want your input before we golive!This year we're making an effort to move much of the surveyprocess to the ember-learn/annual-community-survey GitHub repo.Please review the the list of 2019 survey questionsthis before February 17th and submit feedback asan issues on that repo.201 Created began this annual survey ofthe Ember community in 2015. Over the past four years, data from the survey has helpedus measure progress on issues as wide ranging as diversity and browser support.In 2017, free text responses were permitted for the first time, giving communityparticipants a way to provide feedback to the project and project leadership anew way to hear their voices. As 201 Created steps away, it istime to promote the annual survey to an official project of the Ember LearningTeam. Thank you 201 Creat

As many of you know, Ember 1.10 will be the first version of Ember that uses HTMLBars as its templating engine. With this change you may need to change the way you compile your templates.The HTMLBars API is evolving and not 1.0.0 yet, so to ensure that templates are compiled compatibly with your Ember version we have updated the Ember build system to generate a ember-template-compiler.js file alongside every build of Ember. This template compiler can be used server-side for precompilation or in the browser to compile templates on the fly. If you do not need to compile templates at runtime (in the browser) the ember.debug.js or ember.prod.js file alone is sufficient. There is no need to include a runtime dependency. This is a departure from previous versions, where you would always include either handlebars.js or handlebars.runtime.js.Most of the time you will use a third party library like ember-cli, ember-cli-htmlbars, or grunt-ember-templates to precompile templates, but this post wi

In our end of year series-"Countdown to The New Year: 31 Days of Ember Addons" we showcase a new addon each day until the new year, and we hope you have fun hearing about our favorite addons!Day 16For day 16 of our Countdown to The New Year we want to highlight and addon that truly brings the entire Ember community from all locales together: ember-intl!What It DoesThe ember-intl addon is probably one of the most popular addons used in Ember apps today. As the go-to solution for bringing internationalisation to our application, it allows us to manage translations, date, time, number and currency formats in more than 150 languages!Why I Like ItThe rich ember-intl service API and many useful template helpers help us to add new locales to our apps continually as our product's user base grows globally.For those of us who have lots of languages to support in their application, ember-intl even allows us to load translations asynchronously - making sure that the size of the bundle that determi

This is the tenth in our DecEmber series-"Countdown to The New Year: 31 Days of Ember Addons". We plan to highlight a new addon each day until the new year, and we hope you'll join us for the fun!Day 10Let's talk about ember-a11y-testing.What It DoesThe ember-a11y-testing addon is a wrapper around Deque Labs'axe-core accessibility(a11y) testing engine that helps you identify accessibility issues in your Ember app & provides useful information on how to solve them.Why I Like ItLike many of you out there, I too developed webapps without realizing the impact that accessible apps can have on users. In fact, Istarted learning about a11y problems through this addon when I added it to a few apps that I was working on when this addon gotreleased back in 2015.While there's more to building accessible apps than automated tools (like this addon) can help with, it does help ensure thatcommon a11y violations are captured before they can make their way to users.The best part about this addon is that

This is the ninth in our DecEmber series–"Countdown to The New Year: 31 Days of Ember Addons". We plan to highlight a new addon each day until the new year, and we hope you'll join us for the fun!Day 9Until recently, converting Ember templates to use Angle Bracket invocation was a tiresome and manual task. With the latest version of ember-angle-brackets-codemod, you get a smarter, more complete codemod to change your templates in a flash!What It DoesBefore Angle Bracket invocation, nearly every template construct in Ember was invoked using Handlebars {{doubleCurly}} syntax. This made differentiating between components, helpers, and plain values incredibly difficult. Angle Brackets alleviate most of this ambiguity. But what if you wanted to change every double curly component invocation to Angle Brackets? That task could take forever (especially if you cant reliably tell the difference between everything in your templates)! The Angle Bracket Codemod eases the transition in a few steps:I

This is the seventh in our DecEmber series–"Countdown to The New Year: 31 Days of Ember Addons". We plan to highlight a new addon each day until the new year, and we hope you'll join us for the fun!Day 7According to Wikipedia's History of Animation-The Roman poet and philosopher Lucretius (c. 99 BCE – c. 55 BCE) wrote in his poem De rerum natura a few lines that come close to the basic principles of animation: "…when the first image perishes and a second is then produced in another position, the former seems to have altered its pose. Of course this must be supposed to take place very swiftly: so great is their velocity, so great the store of particles in any single moment of sensation, to enable the supply to come up."Today, we write such poems in code, using ember-animated.What It Doesember install ember-animated is an invitation for creativity. This addon provides animation primitives and some built-in transitions that help bring interfaces to life! You can animate across route chang

This addon provides a native Ember component library for some of the more commonly used Bootstrap components.The ember-bootstrap addon can help you can integrate Bootstrap into your application quickly, and in an idiomatic Ember manner.There are many related Ember addons that integrate with Ember Bootstrap to provide additional features on top of Ember Bootstrap, such as form validation and changesets.Ember Bootstrap - Why I Like ItIf you're looking to add Bootstrap to an Ember application, ember-bootstrap makes doing so incredib

This is the 28th in our DecEmber series–"Countdown to The New Year: 31 Days of Ember Addons". We plan to highlight a new addon each day until the new year, and we hope you'll join us for the fun!Day 28For the 28th edition of Countdown to The New Year we're going to take alook at ember-changeset.What It DoesManaging data associated with forms can sometimes be unwieldy. As a result, we have borrowed concepts from the Elixir community to give you the ability to prevent mutating the underlying object until the last possible moment when you have decided to apply the changes and the data is valid. This functional approach to validations has proved to be quite useful.This addon works in conjunction with ember-changeset-validations to provide you with out of the box validations to validate the format of a certain input, ensure passwords pass a minimum security threshold or even let you build your own custom validator!Why I Like ItRecently I rewrote ember-changeset to fix long outstanding bugs,

This is the second in our December series–"Countdown to The New Year: 31 Days of Ember Addons". We plan to highlight a new addon each day until the new year, and we hope you'll join us for the fun!Day 2Today we are going to look at one of our community's most popular addons- ember-cli-mirage.What It DoesThe ember-cli-mirage addon is a client-side server to help you build, test, and demo your Ember app. It helps developers be more productive by providing ways to generate fake data, allowing front-end engineers to spend more time focusing on the UI.Why I Like ItAs I was informally polling the community about their favorite Ember addons, ember-cli-mirage came up A LOT. For good reason, too. It's well-supported by the addon maintainers, there's a dedicated documentation site, and there's support on the Ember Community Discord server in the #ec-mirage channel."It’s a part of the ecosystem I dearly miss when I work with other frameworks."As an extra bonus, EmberMap has generously made their

It's that amazing / critical / \<add your hype word of choice here>!In all seriousness, let me tell you why I love Sass and why I encourage you to try out ember-cli-sass today.What It Doesember-cli-sass uses Sass to preprocess stylesheets in your Ember app (or addon). That's just a fancy way of saying you will have an easier time expressing how you want to style your app.The addon also supports common, advanced use cases for Ember projects:Source maps by default in developmentSupport for outputPaths configurationAbility to specify includePathsAbility to edit Sass in Chrome Dev ToolsWhy I Like ItThere are two areas to examine here: (1) why I love Sass, and (2) why I love ember-cli-sass.Why I Love SassSass (Synt

This is the 24th part of our DecEmber series–"Countdown to The New Year: 31 Days of Ember Addons". Highlighting a new addon each day until the new year starts, we hope you enjoy learning together with us!Day 24Today we are going to take a look at writing apps in TypeScript - using ember-cli-typescript.What It DoesThe ember-cli-typescript addon sets up everything you need to start using TypeScript in your Ember apps and addons. This includes not only configuring Babel to handle TypeScript, but build-time type-checking, in-browser type error reporting, and a whole set of custom blueprints for generating TypeScript versions of everything from routes and controllers to services to components. ember-cli-typescript also helps addon authors write their addons in TypeScript by handling automatic precompilation and type definition generation when publishing.Why I Like ItStatic typing is a lifesaver, especially in ambitious apps with complex structures and many moving parts. It helps speed up de

This is the 26th in our December series–"Countdown to The New Year: 31 Days of Ember Addons". We plan to highlight a new addon each day until the new year, and we hope you'll join us for the fun!Day 26Let's highlight how you can update Ember your projects with ember-cli-update.What It DoesBesides package updates like ember-source and ember-cli, there are more files that are updated when a new version of Ember releases.Tweaks to testem.js or .eslintrc.js may be missed if you're not tracking those files changes (via something like ember-new-output).ember-cli-update was created to update those kinds of files along with package.json changes for you.It can also run codemods against your newly installed versions.A new feature is on its way where it can maintain any blueprint, not only the official Ember blueprint.The idea is that you can make one blueprint for your organization, and keep your projects up-to-date like ember-cli-update does today.You could also keep default blueprints that shi

This is the twenty-ninth in our DecEmber series–"Countdown to The New Year: 31 Days of Ember Addons". We plan to highlight a new addon each day until the new year, and we hope you'll join us for the fun!Day 29Before I took this assignment, I didn't know anything about ember-code-snippet. Now, I'm glad that I did. This addon surfaced in 2015, has received regular updates, and powers many of my favorite addons. (Can you guess how?)What It Doesember-code-snippet lets you render code snippets in your app (or addon). Quite handy if you want to create a technical blog or document your components.It provides a helper called get-code-snippet so that (1) you can save code snippets in a dedicated folder and (2) create your own component to customize their look.To illustrate the use, we'll consider a code snippet from the Ember.js Octane vs Classic Cheat Sheet:// my-app-name/snippets/make-your-own-elementId.jsimport Component from '@glimmer/component';import { guidFor } from '@ember/object/intern

This is the 18th in our DecEmber series–"Countdown to The New Year: 31 Days of Ember Addons". We plan to highlight a new addon each day until the new year, and we hope you'll join us for the fun!Day 18Today we are going to look at the 11th most popular addon on Ember Observer: ember-composable-helpers.What It DoesThe ember-composable-helper addon provides composable helpers for Ember apps, which allows for more declarative templating.Now, the first time I read that sentence, I thought, "huh what?" so I want to break it down a little more.This addon provides helpers. Useful helpers (like filter-by, repeat, and group-by, to name a few. These helpers can be used together (imagine using group-by in conjunction with filter-by…go ahead, imagine it, I'll wait…).The declarative bit means that we're telling our template what we want to do, succinctly; ember-composable-helpers tells our app how to do it, saving us time and increasing our productivity.Why I Like ItI think this addon is the bee's

This is the fifth in our DecEmber series–Countdown to The New Year: 31 Days of Ember Addons". We plan to highlight a new addon each day until the new year, and we hope you'll join us for the fun!Day 5Let's talk about ember-concurrency.The experience is part joy, part tragedy.The joy comes from having elegant, straightforward solutions for things like debouncing.The tragedy is that I have to write this code myself when I am working in a non-Ember setting, but I suppose absence makes the heart grow fonder.What It DoesThe ember-concurrency addon helps you "write concise, robust, and beautiful asynchronous code." For example, think about what should happen if a user rapidly clicks a "submit" button. With this addon, there's a nice way to prevent 30 form submissions.Or, what if an API request takes a long time, and you want to be able to cancel it? Promises won't help you, but ember-concurrency tasks will.Why I Like ItWithout ember-concurrency, it would take a lot of effort to manage starti

This is the 22nd part of our December series–"Countdown to The New Year: 31 Days of Ember Addons". Highlighting a new addon each day until the new year starts, we hope you enjoy learning together with us!Day 22Today we are going to take a look at creating apps with style - using ember-css-modules.What It DoesWith the addon ember-css-modules, styling à la CSS Modules is only one ember install away.CSS Modules allow us to write styles which are scoped to particular parts of our application by default and allow style sharing by explicit opt-in mechanisms. The ember-css-modules addon helps us to co-locate css files next to our components, routes and controllers following Ember's file name conventions.Why I Like ItMaking the apps we are building look awesome can be really fun! But maintaining a growing CSS code base can also be really hard. CSS Modules are a great way to modularise our styles in a way that they apply locally to only the exact component or route we wrote them for by default.

This is already the second to last edition of our December series-"Countdown to The New Year: 31 Days of Ember Addons". In this series we are highlighting a new addon each day until the new year, and we hope you'll join us for the fun!Day 30On the 30th day of our Countdown to The New Year we want to feature an exciting Ember addon to make your test suite fun to work with: ember-exam!Learn more about ember-exam on Ember Observer.What It Doesember-exam is an addon that allows to have more control over running your ember-qunit (Ember's default testing framework) and ember-mocha test suite. It extends from the default Ember CLI test command, allowing you run it as you would ember test.Why I Like Itember-exam allows us to run tests in parallel which can greatly reduce the overall run time of our test suite. Using the --random option of this addon, we are able to run tests in random order; this helps us to uncover interdependencies between test cases which would be hard to spot otherwise. An

We plan to highlight a new addon each day until the new year, and we hope you'll join us for the fun!Day 27For the 27th edition of Countdown to The New Year we're going to take alook at ember-in-viewport.What It DoesDoes your app use scroll event listeners or getBoundingClientRect to determine if an element on your page is in the user's viewport? If so, you have come across the perfect addon for you to observe DOM elements!Common use cases for ember-in-viewport include lazy loading images, infinite scrolling (see ember-infinity) and/or tracking advertisement impressions. This is a flexible and performant library to give your users the performance they need when visiting your site.Recent additions have added our own {{in-viewport}} modifier, allowing you to "observe" elements in template only components! See the Modifiers section for more examples.Why I Like Itember-in-viewport supports browser

This addon helps us to integrate the functionality of Leaflet.js - an open-source JavaScript library for mobile-friendly, interactive maps - into our Ember app.Why I Like ItLeaflet.js is already a great library built with simplicity, performance and usability in mind. The addon ember-leaflet makes the developer experience even better for us: we can build complex, multi-layered street maps directly in our templates using the useful layer components provided by the addon API. This makes creating intera

This is the 21st in our DecEmber series–"Countdown to The New Year: 31 Days of Ember Addons". We plan to highlight a new addon each day until the new year, and we hope you'll join us for the fun!Day 21Today we are going to take a look at making maps in Ember with ember-mapbox-gl.What It DoesHave you ever wondered how to make maps in Ember? No? Okay, but you should!This post is about adding an interactive map to your Ember project. By the end of this post, you'll have a map of the location of your company's business (provided that it has some physical location in Cartesian space).(Note: I'm not talking about these kinds of maps, although they're not totally unrelated).Every time I need to solve a problem in Ember, I do a quick search through the Ember addon ecosystem.Yes, it's satisfying to solve the problem yourself, but it's smarter—and quicker—to use someone else's code. Shoulders of giants, people. Now, web mapping is a pretty complicated suite of technologies, so the temptation to

Day 3This is the third in our DecEmber series–"Countdown to The New Year: 31 Days of Ember Addons". We plan to highlight a new addon each day until the new year, and we hope you'll join us for the fun!Today we are going to look at a rising star in our addon ecosystem- ember-modifier.What It DoesThe ember-modifier addon provides an API for authoring element modifiers in Ember. It mirrors Ember's helper API, and has forms for writing both simple functional modifiers and more complicated class modifiers.A modifier can add customized, automatic behavior to a DOM element, such as tracking scroll position or adding new event listeners. After you write a modifier, you can use it in a template like this:<div {{my-modifier}}> Some more content</div>Developers who have tried out the Octane preview might already be familiar with ember-render-modifiers, which provide some modifiers like {{did-insert}} out of the box. With ember-modifiers, you can go beyond the box to build whatever your app needs!

We plan to highlight a new addon each day until the new year, and we hope you'll join us for the fun!Day 11This addon ember-page-title provides a helper for changing the browser tab title of the page within your application.What It DoesThe ember-page-title addon is helpful for many reasons, but an important reason is that it is a WCAG success criteria (2.4.2) to provide a page title.A quick tip about page titles! The title of each Web page should:Identify the subject of the Web pageMake sense when read out of context, for example by a screen reader or in a site map or list of search resultsBe shortWhy I Like ItThanks to ember-page-title, you can provide users with an HTML browser title tag so they know where they are within your single-page application (SPA).How to use it:Run ember install ember-page-titleAdd {{head-layout}} to your application.hbs fileInclude the title helper to each page

Exceptionally well-documented, Ember Power Select allows you to create everything from a straightforward list of text items to an asynchronous search driven select which incorporates graphical elements in the list.The addon's website includes a cookbook for more unusual requirements as well as a list of community provided addons which address functionality outside of the scope of Ember Power Select.Why I Like ItI have grown to love using Ember Power Select while developing a CRUD-rich web app which benefits from many instances of select elements dr

We plan to highlight a new addon each day until the new year, and we hope you'll join us for the fun!Day 20For the 20th edition of Countdown to The New Year we're going to take alook at ember-shepherdwhich allows you to add tours to your Ember app.What It DoesThe ember-shepherd addon provides an Ember wrapper for the site tour libraryShepherd, which allows you to seamlesslyconfigure your site tours with an Ember service.It allows you to show new users around your app, introduce new features to existing users, or suggest a flow your users might follow to optimally use your app.It is configurable to show modal overlays or not, and can be hooked up to your existing application flow to conditionally show steps or be controlled manually.Why I Like ItTours are an often overlooked feature of apps, and can be crucial to providing a good user experience. Without them, a user may feel lost in your app o

It takes care of maintaining a client side session and synchronizing it accross tabs and windows, so you don't have to worry about your user signing out in one tab and remaining signed in in others.It comes with a set of authentication providers (OAuth, Device, Torri) and can be customized in case you need to support a different authentication mechanism. It also provides a session service and a series of mixins that will aid you in adding authorization information to your requests, defining which routes should be accessible only to signed in users, and controlling the user session.Why I

We plan to highlight a new addon each day until the new year, and we hope you'll join us for the fun!Day 1To kick things off, we're going to look at ember-sortable.What It DoesThe ember-sortable addon provides sortable UI primitives for Ember apps- this is super useful in the sense that teams don't have to reinvent this very common pattern every time they need it for their own applications!Why I Like ItWhile the ember-sortable addon has been around for some time now, providing a consistent way to add drag and drop functionality to an Ember app, it is the most recent additions that have made this addon especially worth paying attention to. Yicheng Gong, a software engineer at LinkedIn, noticed that the addon was missing accessibility support. He took on the work via the Adopted Ember Addons org, and updated the addon to add the missing features!The addon now provides a keyboard-only way to sor

Today, we look at a useful addon he wrote to help make debugging a little simpler - ember-template-invocation-location.What It DoesThe ember-template-invocation-location addon will allow you to debug things such as the location in a template that a given helper, component, or modifier was invoked from; the invocation site of the thing that invoked that template, and so on up to the root most template (generally a route template). Since this is primarily done in development and test builds, it will not work in production by default.The general goal of this addon is to enable significantly easier debugging. As a result of this, it is expected that the majority of

This is the 19th in our DecEmber series–"Countdown to The New Year: 31 Days of Ember Addons". We plan to highlight a new addon each day until the new year, and we hope you'll join us for the fun!Day 19Today we are going to look at an addon that is part of every new Ember app. The ember-template-lint addon has many new features added recently, and is worth a close look!What It DoesAs you may guess from the addon title, ember-template-lint is a linter for your template files!It checks for mistakes and advises best practices for the markdown in your component and route templates.Because we work in JavaScript, there are different ways something could be done, but often there is an ideal solution that avoids problems down the line.This is where ember-template-lint shines. It will throw warnings and/or errors when you try to break one of these rules.It's extendable and customizable too, so you can get the right combination of rules for your project.Why I Like ItThe ember-template-lint addon

Our December series - "Countdown to The New Year: 31 Days of Ember Addons" aims to highlight a new addon each day until the new year, and we hope you enjoy hearing about addons that bring us joy as well!Day 15On the 15th day of our Countdown to The New Year we want to take a look at a helpful Ember addon which lets us write redesign-proof tests: ember-test-selectors!What It Doesember-test-selectors is an addon that allows us to use additional, test-specific markup in the form of data-test attributes in the dev and test environments of our app. This additional, test-specific markup allows us to select elements in our integration and application tests reliably - even if the HTML markup or CSS selectors change during a redesign of our app.The addon takes care of removing data-test attributes from our production builds automatically, freeing us from the worry that our bundle size might increase as we build and test away.Why I Like ItIf we only rely on CSS selectors or HTML markup to find e

May the 4th edition in our December series be with you! In "Countdown to The New Year: 31 Days of Ember Addons" we highlight a new addon each day until the new year, and we hope you'll join us for the fun!Day 4Today we are going to take a look at ember-tether.What It DoesThe addon ember-tether provides us with a UI component that - once rendered - will render its block to any other target DOM node on the page as configured via the component's attributes. This "tethering" of the component's block to a target somewhere else on the page also retains the component's context - making Ember action handling and data binding possible.Why I Like ItEven though we have a lot of control over how and where Ember apps render UI using routes and components, it's sometimes difficult to implement less conventional UI patterns such as interactive modal dialogs or tooltips for street maps without writing lots of boilerplate. I enjoy using ember-tether for giving me the freedom to render app content where

This is the last of our December series-"Countdown to The New Year: 31 Days of Ember Addons". Thank you for joining us!What a month it’s been! Over the last thirty days, we have showcased different kinds of addons in the Ember ecosystem. In this final post, we’ll show how an Ember app’s default addons come together to form a great developer experience, and we will reflect on the article series as a whole.This article series highlights the real spirit of the Ember community, the ways in which we come together to find a way to say yes to good ideas. It started out as a wish: “Wouldn’t it be nice if we had our own advent calendar blog?” Then, it quickly turned into a refined possibility: “Let’s do a countdown to the new year so we can cover more addons.” From there, it grew into actionable steps: “What does an MVP blog post look like? How about a pre-determined format to make it easier to allow other community members to contribute?” This is one example of how many of our favorite open so

This is the twelfth in our December series–"Countdown to The New Year: 31 Days of Ember Addons". We plan to highlight a new addon each day until the new year, and we hope you'll join us for the fun!Day 12Today we're highlighting ember-svg-jar.What It DoesThere's a reason ember-svg-jar has a 10 out of 10 on Ember Observer! The ember-svg-jar addon enables you to effortlessly use SVG images in Ember apps.Why We Like ItA common theme in the Ember community is zero configuration. In that vein, with ember-svg-jar, you get a visual workflow out of the box to search and preview icons in one place. Check out the live demo and empower your team with this feature!The ember-svg-jar addon helps you reduce the size of your assets. Using svgo, SVGs are automatically optimized, which can cut your file size by half or more. So useful!The addon is flexible and extensible. ember-svg-jar provides an easy-to-use helper {{svg-jar "asset-name"}}, support for both inline and symbol embedding methods, and the

Ember 1.0 Prerelease 2 is out now. This is mainly a bug fix releaseafter 1.0.pre. However, there are a few things you should be aware ofand we'll go over those a bit below. We're still pushing hard toward the a 1.0 beta release but wanted to make some of our bug fixes available in a more formal way. If you want to go ahead anddownload now, you can grab it over on the Github Download Page. What's Changed NowOther than bug fixes, there are a few things we've changed thatcould affect your 1.0.pre apps.{{outlet}} now creates a Metamorph rather than a <div>. This makesit less obtrusive, but you may have to change your HTML or CSS if youwere relying on the <div>.We have removed CP_DEFAULT_CACHEABLE and VIEW_PRESERVES_CONTEXTflags. Both behaviors are now always on.Inline Handlebars templates must always be named now. The default nameis 'application'. This means that <script type="text/x-handlebars">behaves exactly the same as<script type="text/x-handlebars" data-template-name="application">.U

We're pleased to announce the Ember 1.0 Prerelease. It's been a coupleof months since our 0.9.8.1 release and a lot has changed. By makingthis prerelease available we're giving you the opportunity to try outthe feature set for 1.0. Read on to learn what's new along with a fewcaveats.What's NewRouterEmber.js is all about giving you the tools to build ambitious apps onthe web. Here's the thing about ambitious apps: they usually have state.Lots of state. And the bigger your app gets, the harder keeping allof it in your head becomes.Part of being an app on the web is taking advantages of the browser'sstrengths. In particular, the fact that we have URLs to describe whatwe see on our screen is an advantage over native applications. Yourusers want to be able to share that URL on Twitter or Facebook and have their friends see what they're seeing.Ember 1.0 Prerelease includes what we think is the most advanced toolfor modeling your application's state: Ember.Router. The router allowsyou to desc

Today at Ember Camp, we announced the release of Ember.js 1.0 RC1.This release is all about fixing bugs from the pre4 release, andgets us that much closer to a final 1.0 release. Between this releaseand the 1.0 final, we will mostly be focusing on stability and documentation.If you discover any blocking bugs or undocumented areas, please file tickets atthe emberjs/ember.js repo on GitHub and consider helping out.Route ReplacementYou can now transition to a new route without creating an entry in the history:// instead of this, which creates a history entryrouter.transitionTo('index');// do thisrouter.replaceWith('index');In the redirect hook, you can use replaceWith and Ember won't createa history entry.In a controller, you can use replaceRoute (instead of transitionToRoute)to do the same thing.Item ControllerIf you want every item in a {{#each}} to be wrapped in an ObjectController,you can do so:{{#each posts itemController="post"}} {{!-- `this` in here is each post wrapped in an App.P

Today, we're releasing the second Release Candidate of Ember 1.0.As we said when we released RC1, the next few releases will beabout bugfixes and improvements, and should not have any breakingchanges.Namespace Lookup for ControllersIt is now possible to look up controllers that are included in anamespace other than the main application namespace.For example, when using the render helper:{{render 'posts'}}This will render the posts template with the controller App.PostsController, where App is the main application namespace.If you want to use an alternative namespace, you can use a/-separated path.{{render 'blog/posts'}}This will render the blog/posts template with the controllerBlog.PostsController.Using Render With Multiple ModelsIn RC1, you could use {{render 'posts'}} to render the poststemplate using the app's instance of App.PostsController. Usingrender in this way will always render the template using the samesingleton controller.In RC2, we are adding the ability to render a temp

Today we are announcing the third Release Candidate of Ember 1.0.As we said when we released RC1, all releases until 1.0 is finalwill be about bugfixes and improvements, and should not have anybreaking changes.PerformanceSince RC2, a series of performance improvements have landed.When adjacent child views are scheduled for insertion they areare now batched together, and inserted together rather then one ata time.Object deletion is now async, this prevents un-needed churn when destroyinglarge interconnected object graphs.The number of objects allocated during view rendering has been cut down.The ongoing performance effort is being championedby Erik Bryn and Kris Selden.TestingThere have been many fixes and improvements to App#reset, which should nowcorrectly clear application state when invoked. Typically this is only usedfor integration tests.// before each integration testApp.reset();Please Note: App.reset() now brings its own run loop, and no longerneeds to be wrapped in one.Initial

AnnouncementWe have noticed a performance regression, a debug flag was left on by mistake. So if you really want the goodness of RC4 without this regression use this build, we'll have an official release out soon.Today, we are pleased to announce Ember.js 1.0 RC4:This RC4 release of Ember puts us very close to the final 1.0 release.Ember.js 1.0 RC4As we approach 1.0 final, our focus continues to be on bugfixes, performance, andreliability.BREAKING CHANGE: Controller/Model SetupOne of the roles of Route objects in an Ember application is to tellcontrollers which model they should represent.By default, the object that you return from a route's model hook isset as the model property on the corresponding controller. So, forexample, if you have this route:App.PhotosRoute = Ember.Route.extend({ model: function() { return App.Photo.find(); }});The array returned from model would be set as the model property ofthe App.PhotosController. This tells the controller that it shouldpresent that model

Ember.js 1.0 RC5 has been released and is now available from themain website as well as builds.emberjs.com.RC5 fixes several regressions and bugs found in RC4. Notably:A performance regression caused by a change to run loop scheduling hasbeen fixed. Thanks to Erik Bryn forworking on this.Promises returned from a route's model hook could cause the app tohang on page refresh. This has been fixed thanks to Alex Matchneer.The ember-testing package, which contains additional helpers fortesting Ember.js apps, is no longer included in the production build.This means less JavaScript for end users to load over the network.Thank you to everyone who filed issues and pull requests. Please try outRC5 in your applications and report any issues or regressions you findby filing an issue on GitHub.Lastly, thanks to Stefan Penner, whohas been busting his tail to get Ember.js to the 1.0 finish line,including doing the release engineering for these release candidates.Thanks Stef!

Because many Ember.js apps allow users to interact with private data, wetake security issues very seriously.In fact, we're one of the few JavaScript projects that has aclearly outlined security policy and alow-traffic mailing list exclusively for securityannouncements.We want developers to know that they can trust Ember enough to buildtheir businesses on top of it.In that spirit, today we are announcing the release of Ember.js 1.0RC6.1, RC5.1, RC4.1, RC3.1, RC2.1 and RC1.1. These are all securityreleases that address a potential XSS security issue you can learn moreabout by following this link:CVE-2013-4170It is recommended that you update immediately. In order to easeupgrading, the only major change in each release is the security fix.We would like to thank Mario Heiderich of Cure53for responsibly disclosing this issue, working with us on the patchand the advisory, and having patience while we went through oursecurity procedure for the first time.Like a smoke detector or fire extingui

Ember.js 1.0 RC6 has been released and is available from themain website and at builds.emberjs.com. Thisrelease features two big changes: 1) router update 2) Ember Components.Router UpdateThe biggest change is router update (aka "router facelift"), which addressestwo major issues. The first was inconsistent semantics between URL-based transitionsand transitionTo. The second was spotty async support which made it difficult toprevent or delay route entry in cases such as authentication and async code-loading.We have now harmonized URL changes and transitionTo semantics and more fully embracedasynchrony using promises.Additionally, router transitions have become first-class citizens and there arenew hooks to prevent or decorate transitions:willTransition: fires on current routes whenever a transition is about to take place beforeModel/model/afterModel: hooks fired during the async validation phaseFinally there is an error event which fires whenever there is a rejected promise orerror thro

We’re pleased to announce the release of Ember 1.0 RC7 today! If all goes smoothly, this will be our penultimate RC before Ember 1.0. This release includes a number of bug fixes and a few small improvements. We’ve got a few other bug fixes in the queue that weren’t quite ready but this release was overdue and we didn’t want to wait. To that end, we expect to release RC8 next week. Read on for more details on what we changed.Important ChangesRoute#controllerFor no longer auto generates controllersIn some cases, people have been relying on controllerFor to access controllers for routes that have not yet been entered, relying on its auto-generation ability. Unfortunately, this can actually lead to subtle bugs. When entering a route, Ember looks for a controller with a matching name. If that controller isn’t found, Ember generates one according to the type of the route’s model. If the model is an array, we generate an ArrayController; if it’s an object, an ObjectController; if neither, a s

With Ember 1.0 RC8, we have reached the final RC before 1.0 final, whichwe hope to release this weekend if all goes well.This final release candidate comes with a couple of small breakingchanges that we are making before 1.0 because they should have a smallimpact on application code but a large impact on performance.We normally would not make changes of this nature this close to the 1.0final release date. However, the performance improvements were sodramatic we did not want to wait until Ember.js 2.0 to introduce thechange, and we are serious in our commitment to not breaking the APIpost-1.0. This was our last chance to get these changes in beforeputting the final stamp on the 1.0.Both of the changes are related to observers. If you find yourselfwriting code with lots of observers, you may be writing non-idiomaticcode. In general, you should only need to use observers when you arebridging Ember code to other libraries that do not support bindings orcomputed properties.For example, if y

Today, we're excited to announce the final release of Ember.js 1.0.The first commit to the repository that would become Ember.js happened on April30th, 2011, almost two and a half years ago.At the time, Backbone.js was rocketing to popularity. In response to largeJavaScript frameworks like SproutCore, Cappuccino, and Dojo, which tried toabstract away HTML, most web developers began rejecting any solution whosesource code they couldn't read over in an afternoon. The "microlibrary" frenzyhad hit full tilt.However, we knew that as web browsers became more and more powerful, thesesimplistic abstractions wouldn't scale up to the kind of apps that users wouldbegin to demand.We realized that helping developers grapple with the complexity of building100% JavaScript web applications could only happen if we embraced the toolsthat they were most comfortable with: HTML and CSS.Based on the current popularity of frameworks like Ember, Angular and Knockout,it's clear that this strategy turned out to

Hot off the heels of our 1.0 release, we've got two new bundles ofgoodness for you to try out today.First up is Ember.js 1.1.1, the inaugural stable release after ourswitch to a Chrome-like six week releasecycle.Because this is the kickoff release of the new process, there are veryfew new features and the delta between 1.0 and 1.1.1 is very small. Thisrelease is composed primarily of bug fixes and performance improvements,so we recommend you upgrade right away.For a list of exactly what's new, see the CHANGELOG.(If you're wondering why 1.1.1 and not 1.1, there was a regressionintroduced in Ember.Object.create() that could break 1.0-compatibleapps that we didn'tnotice until after we'd tagged the 1.1 release.)To coincide with the stable release, we've also got a new beta releaseof Ember 1.2. Beta releases are intended to get more eyeballs on newfeatures that look ready to go, but may have bugs or edge cases that wehaven't yet sussed out.The only changes between a beta release and the sta

Unfortunately, there was a second regression in 1.1 that didn't getcaught in time to make it into 1.1.1. On that account 1.1.2 is out nowto correct that issue. For more information about the problem seeIssue #3637.We recommend that everyone using 1.1.0 and 1.1.1 upgrade at theirnearest convenience. Head on over to emberjs.com/buildsto download. Our apologies for the inconvenience.Ember 1.2 Beta 2While we were at it, we also released the second 1.2 beta which includesa couple of bug fixes. 1.2.0-beta.2 is also available atemberjs.com/builds.

We are pleased to announce the release of both Ember.js 1.10.0 and thefirst beta in the 1.11 series. This comes as the tenth cycle of ourrelease process that began after 1.0 was released.The 1.10 release represents the effort of at least 50 contributorsacross over 553 commits.The HTMLBars Templating EngineThroughout 2014 the Ember.js community has poured its shared effort intoa new templating solution. This new library, dubbed HTMLBars, makes availablefeatures and performance improvements impossible to support with Handlebars(the previous library). We are delighted to announce the inclusion ofthe HTMLBars templating engine in Ember.js 1.10.HTMLBars will enable the implementation of several APIs described inThe Road to Ember 2.0, and contributesto our continued improvement of rendering performance. Additionally,it will allow us to continue supporting all Ember 1.x template syntax.This long-term effort would not have succeeded without the continuedcontributions of the Ember community and

We are pleased to announce the release of both Ember.js 1.11.0 and thefirst beta in the 1.12 series. This comes as the eleventh cycle of ourrelease process that began after 1.0 was released.The 1.11 release represents the effort of at least 87 contributorsacross over 646 commits.New Features in Ember.js 1.11Bound Attribute SyntaxCurrent Ember developers are familiar with the bind-attr syntax, usedto declare an attribute binding on an HTML element. An originalmotivation for HTMLBars was to improve on this syntax.Ember 1.11 introduces a more intuitive API for attribute binding. Forexample, here the color variable is bound to the class of a div:<div class="{{color}}"></div>The inline if helper can also be used in these contexts:<div class="{{color}} {{if isEnabled 'active' 'disabled'}}"></div>For some attributes, like the disabled boolean, passing a literal valueis desirable. An example:<input disabled={{isDisabled}}>To allow the data-binding of non-string values to boolean properties and

Today we are releasing Ember.js 1.11.1, a patch-level release of Ember thatfixes several regressions introduced in the 1.11.0 release.CollectionView with attributeBindingsDuring the 1.11.0 cycle much effort was put into making sure that attributeBindings usedthe same logic that template bound attributes use. Namely, that attributeBindings useHTMLBars' attribute helpers instead of jQuery's.Unfortunately, this work lead to an error when CollectionView instances were used withattributeBindings specified. This regression is fixed in 1.11.1.Invalid URLsRefactoring in the router initialization process lead to a bug that caused the browsers URLto become out of sync with the correct URL when the back button was pressed while usingHistoryLocation.This regression is fixed in 1.11.1.Handlebars Helper IssuesA couple regressions were fixed for Handlebars helpers with 1.11.1:The inverse template (aka {{else}} block) of Handlebars helpers was not properly accountedfor during the HTMLBars transition.

We are please to announce the release of Ember.js 1.12 and the first beta in the 1.13 series.1.13 beta is the first Ember.js release that includes Glimmer, the new Emberrendering engine, as well as the final batch of Ember 2.0 features. We willdiscuss those details more below.New Features in Ember 1.12Ember 1.12 is a relatively light release, and includes features that move Embercloser to ES6 class syntax and the first parts of the internal implementationneeded for a stable release of the FastBoot addon.New Computed SyntaxPer RFC #11, Ember is introducing anew syntax for computed properties. This change better aligns computed propertysyntax with JavaScript getters and setters and makes writing settable computedproperties developer friendly.It also has the nice side effect of improving performance, as the old syntax,with its two-in-one function signatures, was harder for JavaScript engines tooptimize.The simplest syntax for a computed property is to define the getter as a function:expor

We are pleased to announce the release of both Ember.js 1.13.0 and thefirst beta in the 2.0 series. This comes as the thirteenth cycle of ourrelease process that began after 1.0 was released.The 1.13 release represents the effort of at least 43 contributorsacross over 680 commits.Ember 1.13 is the last release in the 1.x series and the first release that includes the Glimmer rendering engine. It includes a number of deprecations that will ease the upgrade to Ember 2.0, which is due to land in six weeks.Ember 2.0 beta is the first release in the 2.x series. This means that many features deprecated during the 1.x series will be removed in Ember 2.0. If you encounter any unexpected changes in features not marked as deprecated in 1.13 while testing Ember 2.0 beta, please report them immediately. We would like to fix these unintentional regressions before the final release of 2.0 in six weeks.The release of Ember 2.0 beta also means that the first features in Ember 2.1 (most notably angle b

What better way to celebrate the holiday season than with twobrand-spankin' new releases of Ember.js?Hot off the presses, we've got 1.2.0 and 1.3.0 beta on deck foryou. Since we started following a Chrome-like releasecycle, we'll have twonew releases for you every six weeks. 1.2.0 is the newest stablerelease; 1.3.0 beta is the latest beta channel release.Beta releases are intended to get more eyeballs on newfeatures that look ready to go, but may have bugs or edge cases that wehaven't yet sussed out.New in 1.2Loading and Error SubstatesWhile we'd all like to write apps that are fast and bullet-proof,sometimes your backend may be slow to respond, or generate an error,when your Ember app requests a model.Dealing with those cases is much easier in Ember.js 1.2, thanks toconventional loading and error routes.To learn how to set these up, see Loading and ErrorSubstates section of theguides.Non-block form {{link-to}} helperPreviously, the {{link-to}} helper required that you use it in blockf

We are pleased to announce that both Ember.js 1.3.0 and the first beta in the 1.4 serieshave been released. This comes as the third cycle of our six-week releaseprocess that began after 1.0 was released.New in 1.3Non-array Dependencies for ReduceComputedGenerally, using reduceComputed is all about efficiently computing the resulting value, butoccasionally you might need to recompute every time. It is now possible to instructreduceComputed to completely recompute when an item is added/removed (instead of callingthe addedItem and removedItem callbacks).This is done by using either non-array dependent keys or adding .[] to an array dependency.Take a look at the following example:Ember.Object.extend({ // When `string` is changed, `computed` is completely recomputed. string: 'a string', // When an item is added to `array`, `addedItem` is called. array: [], // When an item is added to `anotherArray`, `computed` is completely // recomputed. anotherArray: [], computed: Ember.reduceComputed('st

We are pleased to announce that both Ember.js 1.4.0 and the first beta in the 1.5 serieshave been released. This comes as the fourth cycle of our six-week releaseprocess that began after 1.0 was released.New features in 1.4Property Brace ExpansionIn prior versions of Ember if you wanted to observe both foo and bar on bazyou would need to setup both baz.foo and baz.bar as dependent keys.var obj = Ember.Object.extend({ baz: {foo: 'BLAMMO', bar: 'BLAZORZ'}, something: function(){ return this.get('baz.foo') + ' ' + this.get('baz.bar'); }.property('baz.foo', 'baz.bar')});With the new property brace expansion, you could setup the computed properties dependenciesinstead like: something: function(){ return this.get('baz.foo') + ' ' + this.get('baz.bar'); }.property('baz.{foo,bar}')This allows much less duplication/redundancy when your dependent keys are mostly similar.See the original PR #3538 for more details.Ember.run.bindEmber.run.bind provides a useful utility when integrating with non-Emb

We are pleased to announce that both Ember.js 1.5.0 and the first beta in the 1.6 serieshave been released. This comes as the fifth cycle of our six-week releaseprocess that began after 1.0 was released.New features in 1.5Handlebars Logging of Primitive ValuesThis feature allows you to log primitive values (strings, numbers, etc) from within your templates. Previously, the {{log}} helper only allowed usage of bound property lookup.{{log "**LOOKEY HERE**"}}New Testing HelpersRouting HelpersA few new testing helpers have been added to make it easier to make assertions on the stateof routing in your application (for example to confirm clicking a given link results in aredirect to a specific route).New routing test helpers: currentRouteName, currentPath, and currentURL.Trigger Event HelperA new triggerEvent helper has been created to allow triggering of arbitrary events on an element.triggerEvent('#some-element-id', 'dblclick');Ember.computed.readOnlyGenerally, when you use Ember.computed.

We are pleased to announce that both Ember.js 1.6.0 and the first beta in the 1.7 serieshave been released. This comes as the sixth cycle of our release process that began after 1.0 was released.Delays DetailedAs many of you know, the 1.6 release is the first to be published after converting thecodebase to ES6 modules. The 1.6+ builds are now transpiled by the es6-module-transpilerinto AMD and use a small AMD loader to handleloading the transpiled modules. Unfortunately, adding the additional loader overhead onboot has a fairly significant performance impact on boot speed of older mobile clients(approximately 5-10% boot time penalty).This regression was brought to our attention before 1.6.0 was intended to ship (lateMay), and we decided to hold the release until a fix could be applied. In retrospect thiswas absolutely the wrong decision. The fix has taken much longer than originally anticipatedand in the meantime folks are stuck with 1.5.1. Many of our users either are not affectedor d

Shortly after Ember 1.6.0 was released a regression was identified regarding custom error substates.The error handling that was added to make debugging errors thrown in the Router's promise hooksinadvertently caused the error substates to be completely ignored.For more details review the following links:Failing JSBin from the original bug report.Fixing PREmber.js 1.6.1 CHANGELOG

We are pleased to announce that both Ember.js 1.7.0 and the first beta in the 1.8 serieshave been released. This comes as the seventh cycle of our release process that began after 1.0 was released.This release brings bug fixes, potentially breaking changes and new features.New FeaturesNestable this.routeThis change removes the restriction that only this.resource can have nestedchild routes.Prior to this change, using this.resource would reset the namespace and in orderto preserve it you had to do the following:this.resource('foo', function() { this.resource('foo.bar', function() { this.resource('foo.bar.baz', function() { // All this repetition to get an // intuitively-named FooBarBazRoute }); });});this.route can be nested like this.resource, but unlike this.resource, the namespaceof child routes is appended rather than reset to a top-level namespace, allowing the above to bewritten as:this.route('foo', function() { this.route('bar', function() { this.route('baz', function() { // uses

We are pleased to announce that both Ember.js 1.8.0 and the first beta in the1.9 series have been released. This comes as the eighth cycle of our releaseprocess that began after 1.0 was released.This release represents the effort of at least 40 contributors across over 600 commits.Major rendering-layer refactor ("metal-views")In previous versions of Ember.js, the HTML of a page was created (viaHandlebars) and assembled (via the render tree) using string concatenation. InEmber.js 1.8, fragments of a page are still created (via Handlebars) asstrings, but are then parsed into DOM and assembled as a DOM tree.Metal-views is the first part of the HTMLBars effort to land in Ember. It isan important step towards the complete removal of strings from the Ember.jsrendering pipeline.Introducing HTMLBars into Ember incrementally demonstrates the community'scommitment to semantic versioning, and to improving the framework withoutabandoning existing codebases.Some of the immediate benefits of this re

Today we are releasing Ember.js 1.8.1, a patch-level release of Ember thatfixes several minor regressions introduced in the 1.8 release.Throw exception when attributeBindings includes classPrior to 1.8, it was possible to make class part of attributeBindings and havethose values merged with classNameBindings. For example, with the following templateand code "from-template" and "from-class" would be merged into the DOM node's classlist.{{foo-bar class="from-template"}}App.FooBarComponent = Ember.Component.extend({ classNameBindings: [':from-class'], attributeBindings: ['class']});The intent of this code is unclear and the pre-1.8 behavior was unintentional. In Ember1.8.1 an exception is thrown for including class in attributeBindings.View instancesPassing view instances to the {{view}} helper was broken in Ember.js 1.8.

We are pleased to announce the release of both Ember.js 1.9.0 and thefirst beta in the 1.10 series. This comes as the ninth cycle of ourrelease process that began after 1.0 was released.The 1.9 release represents the effort of at least 52 contributors across over 436 commits.The Road to Ember 2.0In early November Tom, Yehuda, and the Ember.js Core Team shared The Road to Ember 2.0.This RFC document acts as a map for the next several releases of Ember.js.Ember.js 1.9 introduces several important deprecations that signal upcoming changes. Additionally, many view-layer internals arerefactored to take advantage of the "streams" observation pattern.Ember.js 1.10 (beta) begins a series of releases that willintroduce new APIs while deprecating ones to be removed in 2.0.To that end, and with much excitement, we are extremely pleased to announce the introductionof the HTMLBars templating engine into Ember.js 1.10. This new rendering pipelinemarks a significant milestone for the framework, and b

Today, the Ember team is pleased to announce the release of Ember.js1.9.1. Ember 1.9.1 fixes one regression and introduces more conservativeescaping of attributes to help developers guard against inadvertent cross-sitescripting (XSS) vulnerabilities.{{view}} Helper & InstancesThe 1.9.0 release introduced a regression where the Handlebars{{view}} helper would only work with Ember.View subclasses, notinstances. In 1.9.1, passing a view instance to the helper has beenfully restored.We intended to deprecate this functionality, not remove it entirely.If your app was relying on this behavior, first, please accept ourapologies for the accidental regression. Second, please considerrefactoring your code to use components instead of views, as support forthis API will be removed in Ember 2.0.XSS Improvements for Bound AttributesXSS vulnerabilities happen when you unintentionally put unescapeduser-supplied content into the DOM, creating a vector for attackersto trick the browser into evaluating Ja

Ember 2.0 is not a traditional major release. After thirteen point releases inalmost two years, we're taking a turn to focus entirely on sweeping outbuilt-up cruft as a foundation for continued progress.Ember 2.0 only removes features that were deprecated as of Ember 1.13, soapps that run on Ember 1.13 without any deprecation warnings should runwithout issues on Ember 2.0.New applications should begin using Ember 2.0 today. Apps requiring Ember-Datashould use Ember-Data 2.0.0-beta.1 (2.0 release coming shortly!).New Features in Ember.js 2.0<This space intentionally left blank!>Major releases of most libraries try to do two things. They introduce new APIs,and remove deprecated ones. Our release focuses on doing one thing well:Instead of introducing new features, the goal of Ember 2.0 is to removeaccumulated cruft.Since Ember 1.0, adherence to semantic versioning has helped us grow an amazingcommunity. Ember powers extremely ambitious applications, and most of thoseapplications have been

Ember.js 2.1 beta is released today. As a minor release, Ember 2.1 will bebackwards compatible with Ember 2.0. Any changes to the API will be additive.This continues Ember's commitment to Semantic Versioningwe began with the 1.0 release.In addition it means many of the first features for Ember 2.2, most notably anglebracket components, have landed in Canary behind a feature flag. If you'reinterested in help us progress with those features, now is a good time totry them out.On to the changes coming in our late September/early October release.New Features in Ember.js 2.1Ember.js 2.1 will be a minor release of Ember. This means changes to the API aremade in an additive, backwards compatible manner. In roughly six weeks, thesefeatures will be part of the 2.1 stable version.A summary of the new features in today's release follows.{{get}} HelperThe {{get}} helper allows dynamic property lookup on objects in templates.For example, these two usages are equivalent:{{user.name}}{{get user "name"

Ember.js 2.1, a minor version release of Ember with additive features only, is released today. This release represents the work of over 82 direct contributors, and over 850 commits.Ember.js 2.2 beta, the branch of Ember that will be released as stable in roughly six weeks, is also being released today.New Features in Ember.js 2.1Changes to the Ember's API in 2.1 are backwards compatible. A summary of the new features in today's release follows.{{get}} HelperThe {{get}} helper allows dynamic property lookup on objects in templates.For example, these two usages are equivalent:{{user.name}}{{get user "name"}}A property with a value of a string can be passed as the second argument,making both the object and the property being read dynamic. For example:{{get user somePropertyName}}For documentation on get, reference the API documentation.Big thanks to @jmurphyau for theimplementation of this feature, and for his excellentember-get-helper addon thatdemonstrated how useful this helper would b

At the same time, it allows addon authors to know which versions of Ember to focus their effort on.Per our usual policy, Ember 2.8-LTS is released six weeks after the 2.8.0 stable release. This allows ample time to fix any reported regressions and ensures a rock solid LTS release. It will continue to receive critical bugfixes for six release cycles (roughly June 2017), and security patches for ten release cycles (roughly February 2018).Meanwhile, Ember 2.4-LTS will continue to receive critical bugfixes for another two release cycles (roughly January 2017), and security patches for s

EmberJS 5.0 embodies the commitment to stability and reliability that developers have come to expect from the Ember ecosystem. The Ember team has worked hard to remove all the deprecations and make us move towards Polaris. Get up-to-date with the latest in Ember and enjoy!This post will cover our release strategy, how to upgrade, what to expect, and deprecated APIs that were removed.This is the first major release under the new release strategy and goals proposed in RFC 830, Evolving Ember's Major Version Process.To summarize, every 12 minor releases, Ember will ship a new major release, which removes anydeprecated code targeted for that major version.When it comes to introducing new features, Ember generally aims to ship new features in minor releases, offering backwards compatibility for existing code at the same time as giving developers the chance to try out new capabilities.This approach reduces the challenges that teams face for major upgrades, compared to producing big, breaking

What is it like to build an accessible Ember app? With a few lines of code, you can audit your app for problems, get customized advice on how to fix them, and see visual indications of which things on a page need work. We'll walk through an example using the Super Rentals app from Ember's official tutorials. We'll also cover some improvements being made to Ember itself for a better experience out of the box.An accessible app is one that gives all users equal access to information and functionality, including those who use Assistive Technology like screen readers. This kind of work is sometimes abbreviated as a11y. There are set standards called the Web Content Accessibility Guidelines, and in many cases, it's the law.This article was written as of Ember.js version 3.1. The same approach applies for all 2.x apps, with some changes to test syntax. Anyone can write a guest article --- get in touch if you are interested!Using ember-a11y-testingWe don't have to learn a thousand rules to sta

Sometimes, this is not desirable. For example, youmay not know if you have already loaded the post in another request viasideloading, or you want the most up to date information.

These performance changeshave wide-reaching effects into everything you do in Ember Data:querying records, pushing records into the store, and creating records.Since everyone on the Ember Data team works on real apps, we testedthese changes in our applications and saw improvements averaging 50% orhigher around pushing and creating records into the store.Breaking Changesstore.update() has been deprecatedCalling store.update() has been deprecated in favor of store.push()nowhandling partial payloads:var post = store.push('post', { id: 1,

We are pleased to announce the release Ember Data 1.0.0-beta.15. Itincludes many bug fixes as well as several new features. As alwaysthis release can be obtained from npm (for use with ember-cli),rubygems, or bower. The builds are also available as static files atemberjs.com/buildsThe 1.0.0-beta.15 release represents the effort of at least 30contributors across over 168 commits.ImprovementsSnapshot APIIn Ember Data serializers will now be given a snapshot instanceinstead of a record instance when serializing records. A snapshotrepresents the frozen state of a record at a particular moment intime. Its initial purpose is to be passed to serializers instead ofthe real record. This allows the serializer to examine the currentstate of that record in the moment without triggering side-effects,like loading relationships.The snapshot has a different API from a record for accessingproperties so you will know you are working with a snapshot. Usingsnapshot.get is still supported for compatibility

This introduces some pain points i

Beta.17 and Beta.18 contained many bugfixes from the community! Please checkthem out in the CHANGELOG. Thank you to everyone who submittedpatches!While many bugs were stomped, some important changes are worth calling out:(Possibly) Breaking Deprecationsrecord.constructor.typeKey is now record.constructor.modelNameIn Ember Data, when you ask for a model, Ember Data looks its class up usingEmber's Dependency Injection API. When the model class is lookedup, Ember Data stores the type on the model class.For example, when the following code runs in your application:var post = this.store.getById('post', 1);and Ember Data will store the string "post" on the model class:console.log(post.constructor.typeKey); // 'post'Ember Data uses this typeKey property internally when creating and extractingpayloads in Serializers, and when locating models in Adapters. The typeKey isalso currently available on Snapshots, which are passed to adapter andserializer methods. typeKey was previously always normali

As we move toward to using Ember'sDependency Injection framework for consistency, passing these classesdirectly to store methods has been removed. Instead, you should pass adasherized string:var record = store.push('post', {id: 1});To help you upgrade thr

Ember Data 1.0.0-beta.2 has been released.The release fixes a number of bugs, and adds several new features:Fix a number of issues where the code still expected class names(App.Post) instead of module-friendly shorthand (post).Add host and namespace in the RESTAdapterAdd record.rollback()Add support for since token from find all fetchesAdd store.update(type, hash) to update some, but not all attributesImprove subclassability of RESTSerializer and RESTAdapterThanks to Paul Chavard, Toran Billups, Bradley Priest, Kasper Tidemann, Yann Mainier,Dali Zheng, Jeremy Green, Robert Jackson, Joe Bartels, Alexandre de Oliveria,Floren Jaby, Gordon Hempton, Ivan Vanderbyl, Johannel Würbach, Márcio Júnior,Nick Ragaz, Ricardo Mendes, Ryunosuke SATO, Sylvain Mina, and ssuredThanks to everyone who has been porting adapters to Ember Data 1.0!

Since Ember Data v1.0.0-beta.8, a lot has changed. Since we didn't write a blogpost for beta.8, this blog post will contain features in both beta.8 and beta.9.New Release ScheduleSince the first beta release for Ember Data 1.0, Ember Data has typically beenreleased when we felt like critical features or bugfixes were merged. Due to theever changing nature of Ember Data, we'd like to reward Ember Data users forkeeping up with changes by providing more frequent releases until a releasecandidate emerges. Beginning Monday, August 18th 2014, Ember Data will release anew beta version every 3 weeks. The builds will be available on the buildspage, Bower, Rubygems, and soon, NPM.Breaking ChangesObject.create shim requiredEmber Data now requires an Object.create polyfill for environments withoutObject.create or incorrect Object.create implementations such as InternetExplorer 8.

We are proud to announce the release of Ember Data 1.13. Thisrepresents the first stable release of Ember Data since its creationover 3 years ago.As we explained in the The Ember 2.x Projectblog post, going forward Ember Data will be syncing up its releases and version numbers with Ember.js releases.Ember Data 1.13 is the first release of Ember Data that syncs its version with a version of Ember.js. It will be followed by Ember Data 2.0, which will be released alongside Ember.js 2.0. Ember Data 1.13 is fully backwards compatible with Ember Data beta.19, allowing for a smooth upgrade path.Ember Data 1.13 OverviewEmber Data 1.13 is a massive release we are very proud of.The highlight of the Ember Data 1.13 release is a total overhaul of Ember Data's internal format and Serializer API to follow JSON API.Two years ago Tom Dale and Yehuda Katz published a vision for how Ember Data should look in the future and articulated the need for a single, ubiquitous JSON API standard.We are very happy

We are excited to announce the release of Ember Data 2.0, thesecond stable release since 1.13 that includes significant improvements,cleanup, and cruft removal.As previously discussed, Ember Data releases occur inlockstep with Ember, to help developers better reason aboutcompatibility between these libraries. Ember Data 2.0 is designed to beused in tandem with Ember 2.0, and like Ember 2.0, we have used theoccasion of a new major version number to remove deprecated features andclean up the code.Ember Data 2.0 is about removing deprecatedfunctionality, not adding new features. If you've already startedusing Ember Data 1.13 and cleared the deprecations, you should findupgrading to Ember Data 2.0 to be very straightforward.JSON APIIn the Ember Data 1.13 blog post, we described how wehad overhauled Ember Data's internals to use JSON API from top tobottom.Using JSON API dramatically simplified internal code and APIs, but Iwant to emphasize that moving to JSON API internally does not affecty

Previous versions ofEmber Data required users to include both the ember-data package intheir project's package.json file and the ember-data package intheir project's bower.json file. This resulted in confusion becauseupdating ember-data in package.json would not update ember-datain bower.json.To upgrade Ember Data to version 2.3 in your Ember CLI projects pleasedo the following:remove the ember-data package from your bower.jsonupdate ember-cli-shims package to version 0.1.0 ...

This release represents the work of over 27 directcontributors, and over 103 commits.Ember Data 2.8 beta.1, the branch of Ember Data that will be releasedas stable in roughly six weeks, is also being released.Blueprint ChangesIn Ember Data 2.5 there was a change made to the blueprints to usemodule paths when importing instead of importing the default DSnamespace. At the time this was thought to be a minor change and didnot receive much scrutiny. However, in time the Ember Data team hasdiscovered that the changes to the import statements in the blueprintshave made it more confusing for both new and experienced Emberdevelopers.In Ember Data 2.5 and Ember Data 2.6 the following generator command for building a model:ember generate model post content isDraft:boolean comments:has-many user:belongs-toIt would generate the following blueprint:// app/models/post.jsimport Model from 'ember-data/model';import attr from 'ember-dat

EmberData 4.12 Special LTS UpdateIn our 5.0 Announcement we promised extended support for 4.12 LTS beyond just bug fixes.This support extends beyond simple bug-fixes. If minor enhancements can be made to better support new presentation class implementations that support the 4.x series we will willingly accept them. Our goal is simple: we want no one left behind.To this end, here are the changes we currently plan to make for 4.12 to ensure our users can both upgrade to 4.12 from 4.6 and 4.11 more seamlessly and to provide additional tools for users on 4.12 to begin shifting to the RequestManager paradigm as early as possible for their app.Builders and Build utilsThe first LTS release of @ember-data/rest and @ember-data/active-record will have their peer-dependency supported versions set to include ~4.12.3 of @ember-data/store.Once apps have updated from 4.12 to the 5.x LTS they should use the associated release's version to ensure maximum inter-compatibility.@ember-data/request-utils ha

This week, in coordination with the broader Ember project, EmberData released 4.12, its final4.x version, and began iterating towards the first release of the 5.x series.A wrap on 4.xThis final release of the 4.x cycle introduced several new concepts to support a new paradigm for managing Requests and new capabilities for Caching Data.The primary focus of these changes was to support caching Documents and to ensure that Resources are handled opaquely. Loosely defined: A Document encompasses the full response returned by an API request, and can typically be identified uniquely by url. Documents may contain many resources or references to resources, where a resource is defined as some data which your application or the API treats as uniquely identifiable.Note: Historically, Model has mapped to a resource "type" and serves to present the data for a resource. It may be useful to think about resources as the backing data for a Model; however, resources can be far more generic than this and

Although most of our collaboration takes place on Github, IRC(#emberjs on freenode.net), and our Discourse sitethe Ember Data team meets privately everyWednesday at 11am PST through Google Hangout for a weeklydiscussion of all things Ember-Data.Attendees@tomdale,@wycats,@terzicigorSerializer refactorWe discussed how best to refactor the existing serializers, especially the work lead by @BMac to break up theRest Serializer into a JSON Serializer + a Sideloading mixin. While working on it, there were several issues raised, including the problem ofhow to make sure that mixins that extend the JSON Serializer(Embedded records mixin right now, and Sideloading mixin in the future) have theirhooks called in the right order and that they do not interfere with each other.Decided that the refactor into a mixin is a good idea.Tom raised the idea of having a serialization pipeline, but we decided to punt on that for now.Decided to wait on more use cases before deciding whether/and how to reorganize

Although most of our collaboration takes place on Github, IRC(#emberjs on freenode.net), and our Discourse sitethe Ember Data team meets privately everyWednesday at 11am PST through Google Hangout for a weeklydiscussion of all things Ember-Data.Attendees@tomdale,@wycats,@terzicigorPushPayload discussionWe discussed the PushPayload proposal@wycats concluded that the original decision for pushPayload on the store to accept a type argument was a mistake.Decided that instead of creating several new hooks, the best course of actions seems to be to add a normalize method to the store.Thus instead of doing pushAndNormalize from the discuss proposal, one can dostore.push(type, store.normalize(type, payload))It also seems nice to have a normalize method on the store as the inverse of serialize which already exists on the model.Group Coalescing@hjdivad and @terzicigor recently added agroupedRecordsForFindMany hook on the findCoalescingbranch to enable users to decide how to group coalesced reque

A month ago, we told you about our plans for stabilizing EmberData. I'd liketo give you an update on the status of those efforts.First, though, I'd like to thank everyone who has been contributing to EmberData. As an open source project, a healthy, active community is ourlifeblood. In particular, I want to call out Igor Terzic, Stefan Penner,Paul Chavard and Gordon Hempton for going above and beyond the call ofduty.Thanks to their efforts, we've been making steady progress towardstriaging and reviewing pull requests andissues.Additionally, Yehuda and I have been able to devote significant time toworking on Ember Data thanks to the financial support ofAddepar. They have my sincere thanks for beinga company that understands the importance of investing in open source.A New FocusImagine that you are starting a new job as a developer on an existingserver-side web application. On the first day, you begin the process offamiliarizing yourself with the codebase.Since you have experience with th

We are thrilled to share that we have released Ember FastBoot 1.0 (including ember-cli-fastboot addon, fastboot-app-server and other FastBoot libraries).What is Ember FastBoot?Ember FastBoot is a server-side rendering solution for ambitious Ember apps,allowing your Ember apps to use principles of progressive enhancement, such as an initial render of your app without JavaScript.It provides a complete solution for server-side rendering of your app from development to deployment.FastBoot works by running your Ember app in Node and shipping the rendered HTML of your initial requested route in your index.html (which also contains scripts for your app to boot in browser) to the user.This helps you show meaningful content to your user while the JavaScript is being downloaded, and also helps the initial page of your app to paint faster.Once the JavaScript downloads and your Ember app in the browser boots, it takes over the initial rendered HTML.It also helps the content in your Ember applicati

The road to Ember 2.0 has been long and rewarding: the community and team have invested in huge efforts to move Ember to a component-based architecture; we released a stable Ember Data; and we unified our development process with Ember CLI. All in all, we've made huge progress.Unfortunately, our docs efforts haven’t kept up with all of those improvements. We know that many Ember users have been frustrated that they can't find the resources they need to take advantage of new features.Over the next few releases, we'll be focusing on major improvements to the content of the Ember Guides and the process of landing new features so we don't fall behind again.Upcoming releasesHere's what you can expect in the coming weeks and months:Ember Data: Several of us are working hard to update the Models section of the Guides to properly document Ember Data in its stable form. This should be released imminently.Ember 2.1: Several people are working on reviewing the Guides from beginning to end to impr

The first version of emberjs.com was created over 7 years ago, in 2011! Since then there's not only been a major redesign, but countless features, blog posts, guides, examples, and lessons learned added to the site. It's been thrilling to watch the Ember community evolve emberjs.com over the years.201120152018That said, we believe it's time for another redesign of the homepage. The marketing copy doesn't capture many of the amazing innovations that have landed in Ember over the past few years. We want the homepage to reflect how great it is to be an Ember developer in 2018.But first we need your help!We want to find out what makes you continue to use Ember in a world full of alternatives, so we can better communicate Ember's value proposition to others who might find similar success.By taking a few minutes to answer these questions, you can help influence the messaging behind Ember's future homepage and any other marketing materials we create.We really appreciate your time, and thanks!

Each Ember team meets in person at EmberConf. For many of us, it was our first chance to sit down in person and plan together! This is important for us because it allows us spend an entire day getting to know each other and plan for the upcoming year.In order to keep the community updated while we move initiatives forward, we'd like to share with you the major outcomes from our face to face meeting. The learning team (and friends!) spent the day reviewing our current workload, extracting all of the ideas from @locks' brain, and reviewing priorities for the upcoming year.GoalsWe had a few goals for the day:craft a mission statementidentify all of the initiatives that were in the scope of the learning teamput all of the initiatives into categoriesprioritize the categoriesWe were able to identify categories of work that naturally fell in to one of two directions - user support and marketing.

Ember is committed to being a good steward of our collective codebases as part of the Node.js ecosystem. In that spirit we will be following the Node.js Long Term Support Schedule to provide clear guarantees of which versions of Node.js we support and how long we will support them. We will test against the same set of releases which the Node.js Long-term Support Working Group says they support: any "Current", "Active LTS", or "Maintenance" releases.What does support mean?All Ember projects can be expected to work in any of the supported Node.js versions and will support every documented feature. We will not maintain separate branches or classes of support for different Node.js support classifications. For example, Ember CLI can be expected to work the same running on a "Maintenance" Node.js version as it does on a "Current" Node.js version. Not all of our projects presently align to this pattern but we will, over time, coalesce to this state.Meeting this commitment does not come withou

For the past several years, when we've talked about "Ember releases", we were always talking about releases of the Ember codebase itself.In practice, that has meant that in order to put together the full, recommended Ember stack, you needed to figure out not only what Ember version to use, but also what versions of our other libraries and tools worked with it.Starting with Ember 2.0, we will coordinate every release of Ember with releases of the main ecosystem tools maintained by the core team:Ember CLIEmber.jsEmber DataLiquid FireList ViewAll of these tools will share a version number with Ember itself.Upgrading to Ember 2.3 means that you'll get a new version of the Ember tools and a new version of Ember. You'll also get new versions of Liquid Fire, List View and Ember Data designed to work with (and tested against) Ember 2.3.These projects will also ship betas alongside Ember itself, meaning that when Ember 2.3-beta.1 is released, there will be versions of Ember Data, Liquid Fire an

Because developers trust Ember.js to handle sensitive customer data inproduction, we take the security of the project extremely seriously. Infact, we're one of the few JavaScript projects that has a clearlyoutlined security policy and alow-traffic mailing list exclusively for securityannouncements.Today we are announcing the release of Ember.js 1.2.2,1.3.2, and 1.4.0-beta.6 that contain an important security fix:1.4.0-beta.6 -- Compare View1.3.2 -- Compare View1.2.2 -- Compare ViewThese releases contain the fix for an XSS vulnerability thatyou can learn more about on our security mailing list:CVE-2014-0046It is recommended that you update immediately. In order to easeupgrading, the only major change in each release is the security fix(other than 1.4.0-beta.6, which is a normal beta channel release withthe fix rolled in).We would like to thank Hyder Ali of Zohofor responsibly disclosing and working with us on the patchand the advisory.If you discover what you believe may be a security i

The Typed Ember team—Chris Krycho (@chriskrycho), Dan Freeman (@dfreeman), and James Davis (@jamescdavis)—is happy to announce that the @types type definition packages, maintained on Definitely Typed, now have full support for Ember 4.x!TypeScript is "JavaScript with syntax for types.… a strongly typed programming language that builds on JavaScript, giving you better tooling at any scale." Using Ember will never require using TypeScript, but we aim to provide a best-in-class experience of using TypeScript, with benefits for JavaScript users too. Want to try it out? Follow the docs for ember-cli-typescript.This update for Ember v4 types brings two major changes with two big benefits.The two major changes:All APIs which were deprecated during the 3.x cycle and removed in Ember v4.0.0 have been dropped from the types. Amusingly, this includes a number of things which were deprecated in 2.x and removed at 3.0, and even a few which were deprecated the 1.x era and removed at 2.0! Additionall

Ember.js (or should we say Amber.js) turned five years old last December. In some ways, five years is a short amount of time. But when measured in web framework years, it feels like a downright eternity.As Yehuda and I were getting ready for our keynote presentation at this year's EmberConf, we tried to remember what developing web apps was really like in 2011. We knew that the web had changed for the better since then, but I think we both had repressed our memories of how truly awful it was.The Web in 2011The most popular browser in 2011, by a wide margin, was IE8. Today, for most people, IE8 is a distant, half-remembered nightmare.Today, we freely use new language features like async functions, destructuring assignment, classes, and arrow functions. We even get to use not-quite-standardized features like decorators ahead of time thanks to transpilers like Babel and TypeScript. In 2011, however, everyone was writing ES3. ES5 was considered too "cutting edge" for most people to adopt.D

We're thrilled to announce that EmberConf 2023 will take place on July 20-21 at the Oregon Convention Center in Portland, OR. The venue is state-of-the-art and fully accessible. We're excited to offer both in-person and live online attendance options. Tickets are on sale now!This is the first conference back in person since the pandemic, and we're taking all the necessary precautions to ensure a safe and enjoyable experience for everyone attending in person (check out the FAQ page for details on our specific precautions). For those attending online, we're working hard to provide an engaging and interactive experience as well. You might not be there with us in person, but we’ll try our best to make everyone feel included!As we celebrate 10 years since Ember 1.0, we’ll focus on not just Ember’s longevity, but Ember’s modern-day community. The talks and workshops have been specifically chosen to help meet users where they are right now, and the practical challenges they face day-to-day.We

(This post was originally published on www.pzuraq.com)These are exciting times in Ember! With Ember Octane just around the corner, native class support has officially landed in v3.6 (with a polyfill supporting v3.4+), and the Decorators RFC has been merged and will be implemented soon (pending decorators moving to stage 3 in the January meeting). Some time ago, I wrote an article that detailed how to use native classes in Ember, along with best practices for writing them. Since then, some major changes have occured, and I wanted to give a quick update for early adopters and folks who are curious about them in general.This post will focus on changes since the original article and current best practices. We'll be talking about:The Native Class Constructor Update RFCnew vs. createconstructor vs. initClass Fields vs. extend()Avoid Class Field Arrow Functionssuper vs. _super()When It's Ok to Use extend()Avoiding reopen and reopenClassAvoiding EmberObjectMisc.

This post was originally published on mainmatter.comFor anyone who has clicked the link to this blog post but doesn't already know,Embroider is a new build pipeline that compiles Ember apps into spec-compliant,modern JavaScript. Before Embroider, it was somewhat difficult to participate inmodern build-tooling optimisations such as code-splitting and tree-shaking.Embroider allows you to opt-into these behaviours out of the box.Embroider is of critical importance for the entire Ember ecosystem, yet has beenin development for many years with no clear end in sight. The EmbroiderInitiative is spearheaded by Mainmatter with the support of a group of sponsorsto help speed up development on Embroider so that we can make it the defaultbuild system for newly generated Ember apps as soon as possible. This will allowEmber developers to continue leveraging its advantages while benefiting from amodern build system. We hope to see Ember apps being built with Vite before theend of the year.The Embroid

We recently made a significant shift in how we think about versioning in Ember, with RFC 0830: Evolving Ember’s Major Version Process. Starting in the current 4.0 cycle, Ember major versions will be 18 months long, running from the .0 release up to the .12 release, and then starting a new major version.For example, in the current 4.x cycle, we will do minor releases up through 4.12 in April 2023, and then release 5.0 in May 2023. Then we will repeat, with 5.12 arriving in September 2024 and 6.0 coming in November 2024.This is a pretty significant change, so it’s important to say up front the things that aren’t changing:Our approach to minor releases is not changing. We will keep releasing on the same steady cadence. Features will be in, or not, based on whether they’re ready.Our approach to Long Term Support releases is not changing. That means that every major version will have 3 LTS releases over its life: the .4, .8 and .12 releases. Having a minimum of 3 LTS releases is important t

Last month, members of the Ember.js Core Team met in-person and remotely to review the direction that the framework API is headed, work through some architectural design questions, and figure out next steps. In this article, we’ll share a summary of the discussions and themes of the weekend.What happens in a F2F meeting?"F2F" stands for face-to-face, a meeting where members of a core team get together to work on problems or brainstorm in a way that is difficult to do remotely or in one-hour meetings. Each of the core teams of Ember meets at least once a year, often right after EmberConf.All core teams make an effort to keeps notes of their meetings, and you can find the agenda and notes (covering day one) for the framework F2F in the core notes repo.Read on for a summary of what was covered.Octane RFC reviewThe F2F agenda focused on discussing and commenting on open RFCs, especially those related to Ember “Octane”. Octane will be Ember’s first edition release, a minor version release o

As we join Global Accessibility Awareness Day (GAAD) in celebrating its tenth anniversary, we are delighted to announce that the Ember JavaScript Framework has taken the GAAD pledge to make accessibility a core value of our framework.For those who know the project well, this will come as no surprise. It’s no secret that we think that accessibility is an integral part of quality code. Ember.js is committed to providing a well-lit path for developer success, and our plans to make it easier for developers to write accessible code are part of that. In 2020, the Ember Accessibility Strike Team became the Ember Accessibility Working Group, demonstrating our commitment to long-term accessibility growth in the framework.What We've Done So FarEmber has also been shipping improvements with the “accessibility by default” developer experience in mind. These improvements include support for default app language (RFC #635), default page titles (RFC #645), added content to the guides specifically for

As we celebrate Global Accessibility Awareness Day (GAAD), I also want to take the time to celebrate the incredible progress that the Ember community has made in our accessibility (a11y) efforts. Over the past few years, the Ember community has been purposefully strategic about accessibility improvements; it hardly came as a surprise that we made our commitment to accessibility even more visible by taking the GAAD Pledge last year to make accessibility a core value of our framework.Getting Started: Setting GoalsAfter completing an analysis of the accessibility-related shortcomings shared both across all JS Frameworks and in Ember specifically, a tangible list of items that could be improved emerged. It was also clear that additional education of the community was needed to increase mindshare regarding accessiblilty in general.Of course, there is a forever-long list of accessibility improvements to be made across the web; to avoid trying to boil the proverbial ocean, it was important to

After months of work, Glimmer is landing in Canary today.What this means:The test suite passes.We have tested Glimmer on our own apps, and, for the most part, apps boot andrun correctly.There are still known issues (see below), including with the test helpers.At this point, we need community help to identify compatibility issues notcovered by the test suite.We expect to continue improving compatibility with the pre-Glimmer engine forsome time, as new issues come to light.Glimmer is the new rendering engine the Ember community has been working on forthe past several months. It is the first ground-up change to the templatingengine since SproutCore 2.0, and takes advantage of the groundwork laid byHTMLBars to dramatically improve re-rendering performance. It also sets thestage for more performance improvements during the 2.x series, andReact-inspired improvements to the Ember programming model. Best of all, we arelanding Glimmer in Ember 1.13, compatible with the full public API of Ember1

At EmberConf in March of this year, we announced Glimmer.js, alibrary for building modern UI components optimized for the mobile web. I wantedto give an update on what we've been working on since then.There were two primary motivations for releasing Glimmer.js as a standalone project:We wanted people who aren't "all in" on Ember to have a way to incrementallyadopt part of the framework.We wanted a laboratory where we could freely run experiments on what anext-generation component library might look like, without creating churn forEmber users.Because Ember's rendering layer is built on top of the shared Glimmer VM,successful experiments have a clear path to make their way upstream to Emberusers. And, once stabilized, we'd like Glimmer.js to be the default componentAPI for new Ember apps—but it's still too premature to set any timelines forthat today.Unlocking ExperimentationWhile Ember is known for incorporating the best ideas from across the JavaScriptecosystem, it's important that we

After two years in public preview and contributions from dozens of community members, the EmberTypeScript team is excited to announce the release of Glint 1.0!While Glint has been available as an unstable prerelease for some time, the project has nowreached a level of stability and functionality that we're comfortable recommending it even forlarge applications with a low tolerance for churn.What is Glint?In an Ember application, templates are the connective glue that bind together all the differentpieces of your codebase. On its own, however, TypeScript can't see what's happening in yourtemplates, so any typechecking or other helpful aids it provides can only ever operate uponsmall islands of disconnected code, and all of your connections are completely opaque to thetooling.Glint enables TypeScript to understand your templates as well, meaning you getend-to-end type safety for your entire application. You also get editor support for things likedocumentation and type info on hover, jump

Happy Global Accessibility Awareness Day!To mark this occasion, I'd like to talk about the ways Ember already helps you make accessible applications, give you an update on what Ember has been doing to make it easier than ever to create accessible Ember applications, and finally a few things that you can do starting today to make your applications more accessible.Accessibility in EmberBecause Ember is an HTML-first framework, it is straight-forward to write accessible applications from day one. Here are just some of the ways that we have provided a solid foundation for you to build your applications, no matter what scale or what size team you have, or what level of talent you have on your team.Accessibility on our Core Team - As an accessibility expert, I provide feedback on new features while we are designing them, to ensure that we're setting our users up for success. Having that kind of representation on a framework's core team demonstrates Ember's commitment to accessibility and rec

Handlebars 2.0 was released a few weeks ago, and since its release we have received manyrequests to update Ember to allow the use of the latest version. Handlebars 2.0 containsa number of changes the list below represents a few that are likely to affect yourEmber application:Precompiler output has changed, which breaks compatibility with prior versions of theruntime and precompiled output.A JSON polyfill is required to run the compiler in IE8 and below. It's recommendedthat the precompiler be used in lieu of running the compiler on these legacy environments.Lines containing only block statements and whitespace are now removed. This matches theMustache spec but may cause issues with code that expects whitespace to exist but wouldnot otherwise.For more information about the changes please review the release notes.Since the release of Ember 1.0.0, Ember has required Handlebars 1.x. As each new version ofHandlebars has been released we have needed to update our version requirement to allow

IntroductionAt the time of this writing, this feature is available in [email protected] new todo feature in the ember-template-lint addon provides a new option to the existing states for linting rules.With this new functionality, linting issues can be converted into a todo and developers can strategically plan the work to resolve issues in existing code. A todo can be set to automatically become a warning, then an error with the use of a supporting feature called decay days.Previously, running the lint:hbs script (default in an Ember app) would cause ember-template-lint to run on all of the .hbs files, and return a result that included number of warnings and number of errors found.Now, however, we have a new option—we can also include number of todos. First, update the lint:hbs script in the package.json file to use the --include-todo flag (we want to be reminded that we have todos!):"lint:hbs": "ember-template-lint . --include-todo",Next, run the command yarn lint:h

After reviewing this thread, it seems clear that the vast majority ofEmber users who have responded, including people working at largecorporations, are comfortable with dropping IE8 support in Ember 2.0.On the other hand, while there is enormous support for dropping IE9support as well, a number of people still rely on support for IE9, andthe benefits of dropping IE9 in Ember 2.0 are not as strong.After reviewing discussion on the RFC proposal, many in-person conversations with Emberusers in large companies, and reviewing the private data sent to us viaemail, we have decided that Ember 2.0 will support IE9+.So how are we going to manage this transition, and what should you doif your business still requires IE8 support for the time being?1.13 with Extended Browser SupportThe core team will continue to periodically release point releases inthe 1.13 series to patch security bugs and browser compatibilityissues, including issues in IE8.No new features will be added, and we should be clear t

Today I'm happy to announce that Igor Terzic is joining the Ember.jscore team.Igor has been instrumental in the development of Ember Data. He has bothfixed bugs relentlessly and landed major new features, such as therecent work on modelling relationships as entities with a single sourceof truth.Thanks to his hard work, Ember Data is rapidly approaching a stablerelease, and it's no exaggeration to say that we couldn't have done itwithout him.Igor has been maintaining Ember Data diligently for some time now, andwe are overdue in recognizing his efforts via membership to the coreteam. As Ember Data is more than ever a core part of the Emberexperience, we're looking forward to even tighter coordination betweenthe two projects.You can follow Igor on Twitter ifyou'd like to keep tabs as he travels the world. Thank you, Igor, forall of your hard work, and welcome to the core team!

The Ember project is pleased to announce that an improved RFC ("request for comments") process has been implemented.As proposed in RFC #617 "RFC Stages", RFCs will now progress through several stages that now include tracking implementation, release, and completeness of features, as well as design:0 - ProposedA new proposal for a change to Ember or its processes that is offered for community and team evaluation. In practical terms, this is an open pull request on the emberjs/rfcs repo.1 - ExploringAn RFC deemed worth pursuing but in need of refinement. This stage is marked by labeling the opened PR as 'Exploring'.2 - AcceptedA fully specified RFC. Waiting for or in the process of implementation. An FCP is required to advance to this stage. This stage is marked by updated frontmatter in the text of the RFC and by being merged to the main branch of the emberjs/rfcs repo. When the RFC is merged, a PR to advance to the next stage is automatically opened on the repo to provide a coordinatio

As we announced in the inaugural blog post in our Inside FastBootseries, wehave begun working on giving Ember.js developers the ability to runtheir apps in Node.js. Once complete, this feature will allow your usersto see HTML and CSS right away, with the JavaScript downloadingin the background and taking over once it has fully loaded.Before the holidays, we had already succeeded in getting the Ember.jsframework loading in Node.js (where it cannot rely on things like theDOM) without throwing any exceptions. We also were able to get Emberapps booting, parsing URLs, and completing most of the functionalitynecessary to start the app, including loading controllers, routes andmodels, etc.This week, we've made good progress on the next major piece offunctionality: allowing HTMLbars templates to render in Node.js where,again, there is no native DOM available.So how does HTMLbars, a DOM-based templating library, work in anenvironment without a DOM?As it turns out, we can introduce a "virtual DO

Using JavaScript to write fast, interactive web applications has exploded in popularity over the past few years. JavaScript apps offer many strengths over traditional server-rendered applications. Most notably, rich interactions and lightning-fast responses to user clicks allow for UIs that previously were only the domain of native apps.The first JavaScript-heavy applications were productivity apps, and the experience of loading an app on the web, even with a spinner, was far better than the equivalent experience of downloading and installing a native app.Increasingly, though, content-rich destinations such as news or video sites are starting to move to JavaScript to gain the benefits of improved interactivity. Unlike productivity apps, where the user logs in once at the beginning of the day and stays logged in, content sites are loaded many times per day, often via search engines or social sharing.In this context, where the JavaScript app looks like a "normal" web page, loading spinne

I'm very happy to share with you our plan to scale Ember's day-to-daydecision-making and coordination—something we're calling Subteams. We mentionedsome of this in this year's EmberConf keynote, and wanted to expand on thespecific details.Ember.js was once only a view layer for rendering templates in thebrowser, but has grown to become a complete SDK for the web. With onenpm install, you get everything you need to create a modern webapplication.Making things simple for developers often means a lot of coordinationand decision-making behind the scenes. As the number of pieces making upEmber has grown—encompassing not only Ember.js but Ember CLI, EmberData, the Ember Inspector, documentation, and more—we want to ensurethat the Core Team does not become a bottleneck for progress.At the same time, we believe that having a strong vision that everyonecan rally behind is critical to building software that feels cohesive.So how do we ensure that everyone is pulling their cart in the samedirecti

Over the last few years the Ember project and community have grown, and along with it, the Ember brand. We took care and caution to craft an experience and feel that while exciting and ambitious, stayed friendly and approachable. A big part of that is thanks to our friendly neighborhood mascot, the Tomster.The time has come to expand the family. Introducing Zoey.When chatting about the origins of the Tomster for an EmberConf talk last year, Jamie White and Tomster illustrator Lindsey Wilson had chuckled about how a mascot needed to be a little bit like the perfect pop song. Distinct, but just generic enough that all different sorts of people could see themselves in it, just like the one right lyric in the song makes it the anthem of a million different emotions and situations.Tomster's done a great job of that until now, and with the addition of Zoey, even more amazing Ember developers will be able to see themselves in Ember.While Tomster will always be the original friendly face of Em

We frequently receive feedback from new developers about how frustratingit can be to get started with Ember. Yesterday, one of the most activecomment threads on HackerNews was largely about that.We hear you loud and clear. Ember.js is not easy to get started with, and we take that very seriously. We are all working nights and weekends to make the framework as approachable as humanly possible.One of the Hacker News commenters, kanja, nailed it. In response to another commenter who felt like the negative reaction was strong:It's incredibly out of proportion - but people really want to use ember (because it promises all these great things!) and they're frustrated by the docs (because they're not really good for first time users) so this is kind of a flash point.Absolutely right. Ember promises—and, we think, delivers—tremendous value. But ramping up to that point is not easy, and we received this feedback repeatedly and take it very seriously.There was another common sentiment that we'd l

We're pleased to announce the creation of the new Ember Mentorship Program!Mentorship has been a strong theme throughout Ember’s existence. We started with our first core team members pairing together at the creation of Ember, and today it’s one of the foundational parts of our DNA. Now we’re formalizing many of the things we already do, into a more structured, community-wide initiative, so we can do an even better job.Mentorship is a responsibility shared by our entire community, and we’re excited to help it grow. It’s a celebration and elevation of the work that many, many people have contributed to, and a public statement that this is something we care about, prioritize, and intend to keep on doing.Established InitiativesIn addition to some fun new plans, the Ember Mentorship Program umbrella captures and unifies a bunch of existing efforts. Some are face-to-face events, others are remote, and some combine the two.Some of the things we've already been doing:The annual Mentorship Wor

Now that we've shipped Ember 1.0 final, it's time to look forward to futurereleases.The plan moving forward is to adopt a Chrome-like release cycle: more frequent releases with more clarity about where features are in the pipeline.TL;DRThe Ember.js 1.x Schedule:Every six weeks: A new stable version of Ember.js.Every week: A new beta of the next version of Ember.js. WhenEmber 1.1 is released, the first beta of Ember 1.2 will be releasedat the same time.Every day: A new "canary" build, which is the last successful build ofthe day.Every successful build: The ember-latest.js build is updatedAll builds will be available on the new Ember.js Builds section of theEmber website.All new features will start out on the master branch behind a feature flag. Canaryand latest builds will ship with all experimental features, enable-ableat runtime.Beta and Stable releases will only ship with features that the core teambelieves are stable.Read on for more details about how we plan to organize new feature

The preview of the Octane edition of Ember is coming soon, and with all these fantastic new features comes a lot of documentation. Since this requires coordination of many moving parts, we want to outline the approach we're taking, and outlining some ways that the community can contribute.PreparationIn order to prepare for the new edition, the Learning Core Team spent time figuring out how to best transition the existing docs in such a way that was consistent with iterative innovation.One of the goals of improving the guides in general was to improve the learning flow in the guides (see RFC #431). As such, we determined that a change to the table of contents was in order.Updating the guidesAs per the usual standard, we have planned out this work to be able to complete it in an iterative fashion. This was particularly important because we are updating guides as new features for the Octane release are merged into Ember.PhasesThis is roughly the planned phases of the documentation work fo

Ember 3.15 is Octane! Curious what Octane means for web development? This blog post will get you oriented.For a write up of the technical details (upgrade strategies, deprecations, new Ember Data features) see the Ember 3.15 Release blog post.What is Ember Octane?Ember Octane is the best way for teams to build ambitious web applications.Ember has always focused on building the best framework that people with different levels of skill can use together to build web applications. Octane updates Ember's components and reactivity system to make them more modern, easier to use, and just more fun.The Ember Project Recommends OctaneAs of Ember 3.15, the Ember project recommends Octane for new applications and addons. If you create a new app using ember new with 3.15 or later, you will get a new Octane application.Octane is More FunThe Ember Octane edition is, first and foremost, about making it easier and more fun to build Ember applications.The centerpiece of Octane's ergonomic improvements a

Update: The timeline has changed since the initial publishing of this post, and Octane is not 3.14.See the Octane Release Update for the latest news.The Ember community is wrapping up the work for Octane, and we expect to get it over the finish line in time for v3.14!Ember Octane describes a set of new features that, when taken together, represent a foundational improvement to the way you use Ember. It has modern, streamlined components and state management that make it fun to build web applications. With seamless interoperability for existing apps, teams can migrate at their own pace, while developers building new apps start out with the best that Ember has to offer.This article will cover the release plan and how your team can prepare.Release planThe next release of Ember is 3.12, which is an LTS (long term support) candidate. Check out the release blog posts to learn which of Octane's features are already available in stable releases like this one.Ember 3.13 will be feature-complete

The short version: We're still learning from the community as they adopt Octane,and won't be recommending Octane as the default Ember mode in the Ember's 3.14release. You can continue to opt-in to Octane in Ember 3.14, and the developerexperience of doing so is continuing to improve.Octane Feedback has been positiveEmber developers have been able to opt-in to Octane since Ember 3.13. By theirown estimation, some developers have been shipping Octane apps toproduction!This has, as expected, resulted in substantial feedback from the community.The feedback about the new programming model has largely been positive.Not anew app, but @intercom has beenincrementally moving to Octane for the past few months. As of this week,we're running Glimmer components in production. I spent this week pairingwith lots of colleagues, most coming from @reactjs. There isuniversal excitement with Octane!— Gavin Joyce (@gavinjoyce) October5, 2019PolishEmber 3.13 is feature-complete for Octane in the core framewo

Open source project management is different than inside a typical software company. It's an example of the purest form of leadership: you’re getting a bunch of peers all moving in the same direction, despite no formal hierarchy or authority structure. It comes down to building consensus, persuasion, and setting the right examples.The Ember Core Team was formed in 2011 because even decentralized open source communities need leadership and shared direction. As our community and core contributor group grew, there was too much going on to keep all the work under the direct attention of the Core Team. And so multiple other teams emerged organically; first the Ember CLI team and Ember Data, and later the Learning team.The work that all these teams do is equally important. But the historical accident of Ember Core being the first team left Ember Core with numerous varied jobs. It became the coordination point for both technical leadership and overall community support.As often happens, the wa

Ember 4.5 introduced a long-awaited feature: the ability to use normal JavaScript functions as helpers.Today, this means two things:You can use (bound) methods on your backing class as helpers directly.You can define function-based helpers without importing and using helper().In the future, it will also work extra nicely with the upcoming <template> feature!Let's see what each of those looks like.Using methods as helpersEmber developers have often wanted to be able to call methods on a backing class as helpers. This often comes up in an {{#each}} loop where you want to calculate some value using state in the backing class for each item. You could work around this by introducing some other intermediate object via a getter, or by extracting a helper you could call with the state and the item from the loop… but now you can call a method exactly like you would in JS code!Here's a simplified example with a component which can choose to hide items from a list passed in.Backing class:import C

As of today, we are requiring all members of Ember GitHub organizations to have two-factor authentication (2FA) enabled.The following are the relevant organizations:Ember.jsember-cliGlimmer.jsember-dataEmber Learning Teamember-enginesEmber FastBootOnly members of these organizations--those with potential write access--are required to have 2FA enabled. It is NOT required to open an issue, make a PR, or otherwise interact with the organizations on GitHub. However, we strongly recommend enabling 2FA, especially for any account with write access to public repos.When we enabled this requirement any members without 2FA enabled were automatically removed from the above organizations. If you were removed from one of those organizations today, please enable 2FA and contact katie in the community slack or your favorite organization admin to be re-invited. We have formalized this policy after self-auditing our security policies in the wake of yesterday's npm incident. Because developers trust Emb

As we approach the eve of the release of Ember 1.13-beta, it's a goodtime to talk about the transition plan for those of us who have Ember1.11 and 1.12 applications.The high level:Ember 1.13-beta.1 will be released early this week. It will come with thenew Glimmer engine and a series of new deprecations, preparing forcruft removal in Ember 2.0.Ember 1.13 will ship with support for angle bracket components,which also serve as the opt-in for one-way data flow and the entiretyof the other React-inspired programming model improvements.We will continue to fix regressions caused by the Glimmer enginethroughout the 1.13 beta cycle.We plan to release Ember 2.0-beta.1 on June 12, as announced atEmberConf.We will release a point release of Ember 1.13 (likely 1.13.1)together with the release of Ember 2.0. This release will continueto fix regressions caused by the Glimmer engine, and help smooth thetransition to Ember 2.0.We will likely release additional point releases of Ember 1.13 tohelp addres

On November 29th, 2016, the Ember security team was notified that version 2.11.0-beta.1 of the ember-source npm package inadvertently included a file that contained an AWS access key.

Yesterday, we gave you an update on our progress making Ember.js easierto use. One thing we didn't discuss was our plan for Ember Data.It's no secret that, while many developers are building awesome appswith Ember.js, Ember Data still causes lots of frustration due to bugsand a changing, complex API. Documentation about it is also mixed inwith Ember.js documentation, making it difficult for new developers tounderstand what is stable and what is not.To be clear, Ember Data is not a dependency of Ember.js.Discourse, for example, usesits own wrapper around$.ajax.Even though Ember Data is not a dependency of Ember.js, loading datafrom the server is an extremely important part of most web applications,and it's a problem that every Ember.js application will have to dealwith.Our long-term goal is as follows: we don't think most web developers shouldhave to write any custom XHR code for loading data. Strong conventionson the client and strong conventions on the server should allow them tocommu

The headlining feature of Ember 5.1 is stable TypeScript support! 🎉 The framework now publishes TypeScript types built from Ember's own source code, with Ember's strong Semantic Versioning commitment baked in—bringing benefits for both TypeScript and JavaScript users.

If you are JavaScript developer, this will make automatic imports, in-editor framework documentation, and other features work much better for you in your Ember app or addon.

Instead, it rebuilds the dynamic features of Bootstrap with native Ember Components.The UI library enters the Octane-era with this new major version: It introduces full support of angle bracket component invocation syntax and an updated documentation. All components have been refactored to native classes.Ember Bootstrap v3 drops support for some very old versions of Ember, but still supports 2.18+ to ease the migration path. The commitment to backwards compatibility introduced some technical challenges because Ember 2.18 isn't supported by native class polyfill.In add...

The RFC recommends adding a new Identifier API which would contain the name, type, and optionally the namespace fields instead of the current microsyntax. For example:From:getOwner(this).lookup('service:session');To:getOwner(this).lookup({ type: 'service', name: 'session' })From:class Example { @service('global@session') session;}To:class Example { @se...

It talks about what the Native Decorator Support feature from Ember 3.10 means for you and why Decorators are important for Ember's adoption of ES classes.With Ember 3.10, all the core APIs and surrounding ecosystem libraries can start adopting decorators as per the stage 1 or "legacy decorators" implementation which would pave the way for ES classes in Ember. However, the happy path is still to wait until your app is on the Octane release or 3.15 or beyond to start using both ES classes and decorators together for all of your Ember app code.To check out how to upgrade your app, check o...

In the blog, we go through memoization, referential equality, revisions, tags, and how they all work together to provide autotracking for Ember.Memoization, a technique where we cache the previous arguments that a function was called with along with the result they produced in order to minimize excess work, is the foundation of autotracking. However, due to how equality works in JavaScript, we need to make use of referential equality to perform a faster deep-equal wh...

👋 Emberistas! 🐹Watch a deep dive on component primitives 📺, and check out the "Rock & Roll with Ember band" interview series 🎸!Watch: Component primitives deep dive 📺Chris Garrett (@pzuraq) and Scott Newcomer (@snewcomer) deep dived into Ember's component primitives such as the setComponentTemplate, setComponentManager, and precompileTemplate APIs.Chris walks through the problem of formalizing relationships between the JavaScript component and its Handlebars template. This is done by preprocessing the template via the precompileTemplate API and then establishing that relationship to the JavaScript component using the setComponentTemplate API.These primitives are actually public so anyone can make a transform or parser to build their own custom template import syntax. This flexibility means we can experiment using these primitives before finalizing the API. We can even iterate on it later on to find the best fit for our ecosystem.Watch the full video discussion on YouTube!The "Rock...

The differences between the two are slight.

The caveat however was that these modifiers were meant for quickly migrating away from classic Ember components to Glimmer components, because they largely allow you to use the same lifecycle hook methods you've already written while attaching them to these modifiers.The blog outlines several possibilities to avoid using these modifiers:Creating your own custom modifier when behavior is tied to a particula...

👋 Emberistas! 🐹Ember 3.28 and 4.0 Beta Released, open source contributors wanted for Ember v4, reactively handle audio in Octane with ember-stereo, and Twitter thread: Ember is data-first.🎉 Ember 3.28 and 4.0 Beta ReleasedAfter 3.5 years and 28 minor releases, Ember 3.28 marks the end of the project's 3.x series. To ensure a smooth upgrade path going into the 4.x series, 3.28 has been declared an LTS (Long Term Support) candidate. In six weeks, the latest patch version of 3.28 will be promoted to be the latest LTS release and replace 3.24-LTS.We're also announcing the start of the Ember 4.0 beta cycle for all sub-projects. Following the process set in previous major versions, Ember 4.0's beta introduces no new features. Instead, it removes support for deprecated public APIs. We encourage our community (especially addon authors) to help test beta builds and report any bugs before they are published as a stable release in six weeks' time. We also encourage everyone to help maintainers...

👋 Emberistas! 🐹RFC: Asset Import Spec, ember-element-query v4, EmberFest 2021 - best of both worlds, Glimmer cheatsheet, and Glimmer Apollo v0.4.0.✍️ RFC: Asset Import SpecEdward Faulkner (@ef4) proposed a new RFC which defines the standard semantics for what it means to depend on files that are not JavaScript or CSS, like images, fonts, and other media. The ecosystem today mostly relies on broccoli-asset-rev which is a Broccoli plugin that adds fingerprint checksums and CDN URLs to your assets. The RFC argues that the broccoli-asset-rev plugin does not take advantage of the newer capabilities we have in ember-auto-import and embroider. The proposed pull-based design lets code declare what assets it needs and then not worry about how those assets will get delivered is safer and easier to change in the future.import myImage from './hello.png';class extends Component { myImage = myImage}<img src={{this.myImage}} />If this is something you are interested in, please read and discuss the ...

What's up Emberistas! 🐹This week you can read about the Component Templates Co-location RFC 🖇️, the story behind ember-model-select 📔, the launch of ember-intl-analyzer 🚀, and EmberFest 2019 announced 🇩🇰!Component Templates Co-location RFC 🖇️@chancancode opened an RFC around placing the component’s class and template in the same directory on the file system. The proposed change is to move the templates from being located at app/templates/components into the app/components directory, co-locating it with the component’s JavaScript file.This change provides component class/template coupling, a single source of truth for components, resolves deviations from route template conventions, and the lack of a single import. If you'd like to learn more, please take a look at RFC #481. Read, comment, and spread the word about it! 🖊️The Story Behind ember-model-select 📔Often, inspiration for a new idea comes from combining the best of existing ideas.For his first blog post, @nickschot share...

It includes several bug fixes, but here are a few selected ones:A bug was introduced in Ember 3.1 that caused ariaRole to not be appended if this was initially set as being false. The expected behaviour here is that if you initially set the ariaRole to false it should not be appended, but you might want to dynamically change this later on. This is now fixed with Ember 3.1.1.After upgrading to 3.1 some people started seeing errors like Cannot read property 'syscall' of null. This was caused by ComponentDefinitions leaking heap space. This has been fixed in Ember 3.1...

Today the Ember.js Core Team is happy to announce our plans for the release of Ember 3.0. Ember 3.0 will arrive 2.5 years and 18 minor revisions after the release of Ember 2.0. The final release of the 2.x series will be Ember 2.18 on January 1st, 2018.Ember 3.0 removes public API deprecated in Ember 2.x releases. 3.0 does not introduce new public APIs or breaking changes.Traditionally, major releases of software are centered around marketing pitches and new functionality. In contrast, major releases of Ember are “garbage collection” releases. Ember APIs that were deprecated during 2.x but were still supported are purged from the codebase in 3.0. The APIs remaining in 3.0 reflect what we think of as the idiomatic way to build an Ember app.Ember 2.0 was the project’s first attempt at a major release where the transition path for apps and addons was a priority. The community took several important lessons from the 2.0 release cycle, and these have shaped our plans for 3.0. Please take a

Contributors to the Ember project have been hard at work since Ember Octane was released in December 2019.Over the duration of a challenging (and sometimes devastating) year and a half, we've shipped a powerful new feature (Named Blocks) and supported an ecosystem shifting to Octane conventions. We've more closely aligned Ember with wider frontend conventions through improved publishing & build tooling (Embroider) and better support for TypeScript (both through ember-cli-typescript and reducing reliance on type-unsafe framework features).Check out Godfrey's EmberConf 2021 keynote fora more complete walk-through of recent changes in Ember.Announcing Ember 4.0In his EmberConf 2021 keynote, Yehuda shared a name for Ember's next edition: Polaris. In order to unblock Polaris providing the best, most productive experience the Ember project can build, we're going to remove already-deprecated APIs in a 4.0 release.Ember 3.27, which has already been released, was the final version of Ember to i

TL;DR Ember Data 1.0 is coming soon. We have a few last features to land before wecan confidently make guarantees around not breaking the API. Specifically:A guarantee that if one side of a two-way relationship changes, the otherside will remain in sync, even if it hasn't loaded yet.All relationships will become async, but DataBoundPromises will make themwork well in observers, computed properties and in templates.Recall how it took us a few attempts to get the router right, but now we'vegot the best one in JavaScript. Getting Ember Data right has taken longer thanwe thought, but it's here and it's almost ready for a 1.0.Ever since the 1.0 release, developers building apps on top of Ember.js haveappreciated the stability and forward-momentum that our commitment to SemanticVersioning allows.We frequently get asked, "Ember.js is great, but what about Ember Data?" Today,we'd like to give you an update on where Ember Data is and where it's headedsoon.First, the good news: there is only one

There's been a lot of exciting changes going in the Ember.js community, here's a recap of some of the biggest updates.Data Format AgnosticismWhile we believe the vast majority of Ember.js apps will be using JSON forcommunication, there's no reason to restrict it so.To this end we've made two changes to Ember Data's DS.Store:A new extractId method has been added to the adapter for extracting the ID from a data hash, by default this asks for data.id.Any method with the term JSON has been renamed to use Data instead, for instance DS.Serializer's toJSON method has been renamed to toData.If you are using the built-in DS.RESTAdapter, these changes do not affect you.Check out BREAKING_CHANGESfor more information.Adapter Dirtiness HooksIn line with the efforts to decouple Ember.js from REST specifics, we've madesome more changes to how the adapter dirties records in relationships.Previously the store would dirty all the objects involved when a relationship was modifiedand let the adapter decid

Only a few more days left, I hope everyone's had a great 2012,while you get ready for the New Year, here's what's been happening in Ember.New Router APIThe new router API has been merged!We've spent a lot of time incorporating feedback about our firstiteration of the router, and we think you're going to really love whatwe've come up with. It helps you get started quickly, andeliminates the old API that forced you to write unwieldy nested objects.There is a short walkthrough thatdescribes the thinking behind the new API. Full documentation should belanding this week.Embedded RecordsAfter a massive refactor of the Ember Data library, it now fullysupports embedded records, amongst other goodies.As always, check out BREAKING_CHANGESfor information about updating your apps.DS.JSONSerializerIn the last post we talked about the changes in the serialization API's renaming methodsto remove the JSON specificity whilst adding hooks to manage relationship dirtiness.We've now fully extracted all th

It's been a big month for Ember.js, and we're excited about the progressthat we've made. With so much going on, it can be hard tokeep up-to-date with the project, so here's what you need to know.Ember CampWhile we have an incredible network of local meetup groups, EmberCamp is the first national event for the Embercommunity.We've been working hard on making sure that this event is both fun andeducational, and we'll be announcing the lineup of speakers soon.Unfortuately, tickets have sold out, so if you didn't get yours thistime, make sure you grab a ticket next year!While Ember Camp is happening, keep an eye on this website and on ourTwitter account. There will be several announcements you won't wantto miss!PeepCodeWe were fortunate enough to get to spend a day with Geoffrey Grosenbach,reviewing his in-progress PeepCode screencast about Ember.js. He spent alot of time getting to know Ember in-depth, and we think the finalproduct will be invaluable for new developers getting started wit

There's a lot of work happening on Ember.js and sometimes it's hard to keep track of what's going on. Here's what me and Yehuda got done this week.MeetupThe SF Ember.js Meetup on Tuesday (which we actually held in MountainView this month) was a success! It was sponsored by our friends atAddepar, who are also funding me and Yehuda to work on Ember Data forthe next few months. So, big thanks to them!Tony Sherbondy gave an overview of the Addepar app and described howEmber.js has helped them. The biggest "a-ha" moment for me was when hedescribed how they completely changed out the table view that powers bigchunks of the UI, and didn't have to make any changes in the rest of theapp. It's exactly this type of encapsulation that makes Ember a win, andI'm glad to see it happening in real life.I gave a talk on Ember Data, and discussed some of the new APIs we'll beworking on over the next few months. Yehuda gave a talk about the routerproposal. The pork belly buns from the Chairman Baofood tru

Last Friday, the Ember project merged RFC #0724: Official TypeScript Support, committing to make TypeScript an officially-supported language for Ember.js. To make that a reality, we also need to have a team dedicated to maintaining Ember’s types and its TypeScript compiler integrations.Happily, we already have a group of people who do that! For the last five years, Ember has had community-driven TypeScript support, led by the past and present members of the Typed Ember team.The Typed Ember team joins the Framework, Learning, CLI, and Data Core teams as a new Core sub-team: the Ember TypeScript Core Team. Its initial members are the current Typed Ember team: James Davis (@jamescdavis), Dan Freeman (@dfreeman), and Chris Krycho (@chriskrycho).The team will continue to do all the things they have been doing:maintaining TypeScript build integration with ember-cli-typescript and ember-cli-babelinvesting in type-checked templates via Glintsustaining the community types on DefinitelyTyped (un

With the initial launch of the website redesign complete, we're now working on the various sub-domains that all come together to make up the Ember Website experience. We want to share these plans with the community, so that those who want to help know where to pitch in.Community members that want to help should familiarize themselves with the ember-styleguide addon - this is the UI addon that we're using to help us consistently apply the branded look and feel to all of the sub-domains within the website. We've created a handy documentation site, so those who want to help out should read through that before getting started.Next up, we plan to work on the blog! To help out with that, visit the Emberify and Redesign the Ember Blog project board on GitHub. Let us know that you want to help in the #st-website channel on the Ember Discord chat server.The project board shows, roughly, the order in which we plan to do the rest of the work:BlogGuidesAPI DocsDeprecation AppHelp WantedEmber CLI G

Ember's conventions for project layout and file naming are central to thedeveloper experience. It's crucial that we get both the technical andergonomic details right. I wanted to provide an update about ModuleUnification and our plans for the file structure in Ember Octane.In short, we do not plan to ship Module Unification in Octane. Instead,Octane will ship with today's file system layout, with one change: supportfor nested components in <AngleBracket /> invocation syntaxBecause Octane apps will continue with today's file system layout, we want toaddress the largest barrier to <AngleBracket /> adoption today: componentsnested inside other directories.For example, if you have a component located atapp/components/icons/download-icon.js (i.e., nested inside an iconsdirectory), you can invoke it with curly invocation syntax like this:{{icons/download-icon}}However, it's not possible to invoke the same nested component with anglebracket syntax without resorting to clunky workarounds.As pr

Updates To The EmberData Lockstep Versioning StrategyToday the EmberData team is excited to announce changes to how we manage lockstepversioning with the broader Ember.js project.The primary goal of these changes is to improve version-to-version stability for our consumers. We see this being beneficial in several ways.First, by releasing fewer versions that contain no effective changes other than the version bump, we believe consumers will be able to navigate version-by-version and LTS-by-LTS upgrades with greater stability and clarity.Second, if the only changes are bug fixes then these fixes are applied to the latest minorinstead of becoming strung out across multiple minors.Third, this should enable the project to move more carefully at times when more substantive changesare being made.We hope that this new policy will improve the ability for us to invest in upgrade paths forconsumers using older versions by focusing on providing the most robust release targets we can.Policy Changes

Every few months, the Ember core team likes to get together to discussissues face-to-face and set our priorities for the following quarter.This time, we all converged on Portland, Oregon for the weekend tofigure out where to focus our energy in 2014.Build Tools & ModulesWe spent the majority of our time discussing a unified plan thatcombines ES6 modules with fast, robust, full-featured build tools forEmber developers.One thing I love about the Ember community is that it values qualityover raw implementation speed. For us, it's more important to solveproblems than to solvescenarios,because scenario solving leads to fragmented solutions that don't scaleor compose as your app grows.So far, we've held off on endorsing any particular build tool because,while we've investigated all of them thoroughly, the currently-availableoptions all have fatal flaws that make them unpleasant to use as yourapp gets larger.Many people have also been asking us about modules. When we startedEmber, there were
