“Writing clean code is what you must do in order to call yourself a professional.

Web Components Work Great with htmx
</> htmx - high power tools for html
People interested in htmx often ask us about component libraries.React and other JavaScript frameworks have great ecosystems of pre-built components that can be imported into your project; htmx doesn’t really have anything similar.The first and most important thing to understand is that htmx doesn’t preclude you from using anything.Because htmx-based websites are often multi-page apps, each page is a blank canvas on which you can import as much or as little JavaScript as you like.If your app is largely hypermedia, but you want an interactive, React-based calendar for one page, just import it on that one page with a script tag.We sometimes call this pattern “Islands of Interactivity”—it’s referenced in our explainers here, here, and here.Unlike JS frameworks, which are largely incompatible with each other, using islands with htmx won’t lock you into any specific paradigm.But there’s a second way that you can re-use complex frontend functionality with htmx, and it’s Web Components!#Pract

Next.js to htmx — A Real World Example
</> htmx - high power tools for html
Over 6 years ago, I created an open source URL shortener with Next.js and after years of working on it, I found Next.js to be much more of a burden than a help. Over the years, Next.js has changed, and so did my code so it can be compatible with those changes.My Next.js codebase grew bigger, and its complexity increased by greater size. I had dozens of components and a list of dependencies to manage. I ended up maintaining the code constantly just to keep it alive. Sure, Next.js helped here and there, but at what cost?I asked myself, what am I doing on my website that is so complex that needs all that JavaScript code to decide what to render and how to render on my webpage? Next.js was trying to render the webpage from the server side, so why won’t I send the HTML directly myself?So I decided to try a new route—some might say the good ol’ route—and choose plain HTML and use the help of htmx for that.#VideoWatch me go full in details here:#The processReplacing my components with the equ

Why Gumroad Didn't Choose htmx

At Gumroad, we recently embarked on a new project called Helper. As the CEO, I was initially quiteoptimistic about using htmx for this project, even though some team members were less enthusiastic.My optimism stemmed from previous experiences with React, which often felt like overkill for our needs. I thought htmxcould be a good solution to keep our front-end super light.

You Can't Build Interactive Web Apps Except as Single Page Applications... And Other Myths

Inevitably,someone claims it’s impossible to build a high-quality application without using a single-page application (SPA)framework like React or AngularJS. This strikes me as odd because, even before the SPA revolution, many popularmulti-page web applications offered excellent user experiences.Two years ago, I set out to build an observability platform and chose to experiment with amulti-page application (MPA) approach using HTMX.

Web Security Basics (with htmx)
</> htmx - high power tools for html
As htmx has gotten more popular, it’s reached communities who have never written server-generated HTML before. Dynamic HTML templating was, and still is, the standard way to use many popular web frameworks—like Rails, Django, and Spring—but it is a novel concept for those coming from Single-Page Application (SPA) frameworks—like React and Svelte—where the prevalence of JSX means you never write HTML directly.But have no fear! Writing web applications with HTML templates is a slightly different security model, but it’s no harder than securing a JSX-based application, and in some ways it’s a lot easier.#Who is guide this for?These are web security basics with htmx, but they’re (mostly) not htmx-specific—these concepts are important to know if you’re putting any dynamic, user-generated content on the web.For this guide, you should already have a basic grasp of the semantics of the web, and be familiar with how to write a backend server (in any language).

So, so true.Unfortunately, the language in that excellent medium post is academic and, without a solid grasp of theoretical HTML,many of the more important points in it will go over a typical web developers head.

Is htmx Just Another JavaScript Framework?
</> htmx - high power tools for html
One of the most common criticisms of htmx, usually from people hearing about it for the first time, goes like this:You’re complaining about the complexity of modern frontend frameworks, but your solution is just another complex frontend framework.This is an excellent objection! It’s the right question to ask about any third-party (3P) code that you introduce into your project. Even though you aren’t writing the 3P code yourself, by including it in your project you are committed to understanding it—and refreshing that understanding if you want to upgrade it. That’s a big commitment.Let’s break this criticism down into its constituent parts, and determine exactly how much htmx indulges in the harms it claims to solve.#The difference between a library and a frameworkSome htmx defenders jump to our aid with: “htmx isn’t a framework, it’s a library.” This is probably incorrect.“Framework” is a colloquial term—there’s no hard rule for the point at which some third-party code evolves from a “

One objection that we sometimes hear to htmx and hypermedia is some variation of the following:Well, it might work well for something small, but it won’t scale.It is always dangerous to provoke us with essay-fodder and so lets dig into this claim a bit and see if we canshed some light on whether Hypermedia-Driven Applications (HDAs) can scale.#ScalingFirst of all, let’s define the term “scaling” and then the contexts that word can be used in development. In a softwarecontext, scaling typically means the ability of the software to handle “larger” things. Those things can be:More nodes in a general systemMore user requests (scaling your individual applications performance)More features (scaling your codebase)More complex featuresMore developers (scaling your team size)Each of these sense of the word “scaling” demand their own analysis with respect to HDAs.#Scaling Nodes In GeneralAlthough this isn’t of much interest to individual developers making decisions about their own applications,

Why htmx Does Not Have a Build Step
</> htmx - high power tools for html
A recurring question from some htmx contributors is why htmx isn’t written in TypeScript, or, for that matter, why htmx lacks any build step at all. The full htmx source is a single 3,500-line JavaScript file; if you want to contribute to htmx, you do so by modifying the htmx.js file, the same file that gets sent to browsers in production, give or take minification and compression.I do not speak for the htmx project, but I have made a few nontrivial contributions to it, and have been a vocal advocate for retaining this no-build setup every time the issue has arisen. From my perspective, here’s why htmx does not have a build step.#Write Once, Run ForeverThe best reason to write a library in plain JavaScript is that it lasts forever.

#REST copy-pastas#Ackshually…I’d just like to interject for a moment. What you’re referring to as REST,is in fact, JSON/RPC, or as I’ve recently taken to calling it, REST-less.JSON is not a hypermedia unto itself, but rather a plain data format madeuseful by out of band information as defined by swagger documentation orsimilar.Many computer users work with a canonical version of REST every day,without realizing it. Through a peculiar turn of events, the version of RESTwhich is widely used today is often called “The Web”, and many of its users arenot aware that it is basically the REST-ful architecture, defined by Roy Fielding.There really is a REST, and these people are using it, but it is just apart of The Web they use. REST is the network architecture: hypermedia encodes the stateof resources for hypermedia clients.

Hypermedia Clients
</> htmx - high power tools for html
Often, when we are being insufferably pedantic in online discussionsabout REST & HATEOAS, we willsay something along the lines of this:JSON isn’t a hypermedia because it doesn’t have hypermedia controls.Look at this JSON:{ "account": { "account_number": 12345, "balance": { "currency": "usd", "value": 50.00 }, "status": "open" }}See? No hypermedia controls.So this JSON isn’t a hypermedia, and, therefore, the API returning this JSON isn’t RESTful.To this, occasionally, a smart and experienced web developer will reply with something along these lines:OK, mr. REST-y pants, how about this JSON?{ "account": { "account_number": 12345, "balance": { "currency": "usd", "value": 50.00 }, "status": "open", "links": { "deposits": "/accounts/12345/deposits", "withdrawals": "/accounts/12345/withdrawals", "transfers": "/accounts/12345/transfers", "close-requests": "/accounts/12345/close-requests" } }}There, now there are hypermedia controls in this response (normal humans call them links, btw) so this

Hypermedia-Friendly Scripting
</> htmx - high power tools for html
The final addition to our constraint set for REST comes from the code-on-demand style of Section 3.5.3 (Figure 5-8).REST allows client functionality to be extended by downloading and executing code in the form of applets or scripts.This simplifies clients by reducing the number of features required to be pre-implemented. Allowing features to bedownloaded after deployment improves system extensibility. However, it also reduces visibility, and thus is only anoptional constraint within REST.--Roy Fielding - Representational State Transfer (REST)#Scripting & The WebIn Hypermedia-Driven Applications we discuss how to buildweb applications in such a manner that they are hypermedia-driven, in contrast with the popular SPA approach, in whichthey are JavaScript and, at the network-level, RPC-driven.In the HDA article we mention scripting briefly:In an HDA, hypermedia (HTML) is the primary medium for building the application, which means that:All communication with the server is still managed vi

When Should You Use Hypermedia?

The trade-off, though, is that a uniform interface degrades efficiency, since information is transferred in astandardized form rather than one which is specific to an application’s needs. The REST interface is designed to beefficient for large-grain hypermedia data transfer, optimizing for the common case of the Web, but resulting in aninterface that is not optimal for other forms of architectural interaction.-Roy Fielding, https://www.ics.uci.edu/~fielding/pubs/dissertation/rest_arch_style.htm#sec_5_1_5We are obviously fans of hypermedia and think that it can address, at least in part, many of the problems that the webdevelopment world is facing today:Hypermedia is often significantly less complex than an SPA approach wouldbe for many problemsHypermedia allows your application API to be much more aggressively refactored and optimizedHypermedia takes pressure off adopting a particular server technology, since you do not have an extensive JavaScriptfront-end code baseWith htmx and the a

Template Fragments
</> htmx - high power tools for html
Template fragments are a relatively rare Server Side Rendering (SSR) template library feature that allow you to render afragment or partial bit of the content within a template, rather than the entire template. This feature is very handy inHypermedia Driven Applications because it allows you to decompose a particularview for partial updates internally without pulling fragments of the template out to separate files for rendering,creating a large number of individual template files.By keeping all the HTML in a single file, it is also easier to reason about how a feature works. This follows theLocality of Behavior design principle.#MotivationLet’s look at how template fragments, in an obscure templating language for java calledchill templates, can help us build an HDA.Here is a simple chill template, /contacts/detail.html that displays a contact:#/contacts/detail.html<html> <body> <div hx-target="this"> #if contact.archived <button hx-patch="/contacts/${contact.id}/unarchive">Unarchive</b

Inother words, if the engine of application state (and hence the API) is not being driven by hypertext, then it cannotbe RESTful and cannot be a REST API. Period. Is there some broken manual somewhere that needs to be fixed?–Roy Fielding, Creator of the term REST REST APIs must be hypertext-drivenREST must be the most broadly misused technical termin computer programming history.I can’t think of anything else that comes close.Today, when someone uses the term REST, they are nearly always discussing a JSON-based API using HTTP.When you see a job post mentioning REST or a company discussing REST Gu

10 Tips For Building SSR/HDA applications
</> htmx - high power tools for html
Building web applications using traditional Server-Side Rendering (SSR) or, saying the same thing another way, buildingHypermedia-Driven Applications (HDAs) requires a mindset shift whencompared with building web applications with Single Page Application frameworks like React.If you come at this style of development with an SPA-engineering hat on, you are likely to be frustrated and miss outon many advantages of this particular architectural choice.Here are 10 tip to help you make the mental shift smoothly, taking advantage of the strengths of this approach andminimizing the weaknesses of it:#Tip 1: Maximize Your Server-Side StrengthsA big advantage of the hypermedia-driven approach is that it makes the server-side environment far more important whenbuilding your web application. Rather than simply producing JSON, your back end is an integral component in the userexperience of your web application.Because of this, it makes sense to look deeply into the functionality available there.

Two Approaches To Decoupling

The central feature that distinguishes the REST architectural style from other network-based styles is its emphasis ona uniform interface between components. By applying the software engineering principle of generality to the componentinterface, the overall system architecture is simplified and the visibility of interactions is improved.Implementations are decoupled from the services they provide, which encourages independent evolvability.-Roy Fielding, https://www.ics.uci.edu/~fielding/pubs/dissertation/rest_arch_style.htm#sec_5_1_5In this essay we will look at two different types of decoupling in the context of web applications:Decoupling at the application level via a generic JSON Data APIDecoupling at the network architecture level via a hypermedia APIWe will see that, at the application level, a hypermedia API tightly couples your front-end and back-end.

HATEOAS
</> htmx - high power tools for html
HATEOAS#Preface: HATEOAS — An Alternative ExplanationThis page is a reworking on the Wikipedia Entry on HATEOAS, which uses JSON.Here we use HTML to explain the concept, and contrast it with JSON APIs. It is a more opinionated explanation of theconcept than would be appropriate for Wikipedia, but it is more correct in our opinion.Hypermedia as the Engine of Application State (HATEOAS) is a constraint of the REST application architecture that distinguishes it from other network application architectures.With HATEOAS, a client interacts with a network application whose application servers provide information dynamically through hypermedia. A REST client needs little to no prior knowledge about how to interact with an application or server beyond a generic understanding of hypermedia.By contrast, today JSON-based web clients typically interact through a fixed interface shared through documentation via a toolsuch as swagger.The restrictions imposed by HATEOAS decouples client and server.

The most familiar form of thislatter style of API today is the ubiquitous JSON API.These two different types of API have distinctly different design needs and, therefore, should use different designconstraints and adopt different goals when being created.Hypermedia APIs:Will be trivially REST-ful, since they are simply what Roy Fielding was describing.Should be driven by the needs of the underlying hypermedia applicationMay change dramatically without versioning information, because hypermedia utilizes self describing messagesShould be passed directly to humans, to maximize the flexibility of the systemData APIs, on the other hand:Will not benefit dramatically from REST-fulness, beyond perhaps Level 2 of the Richardson Maturity ModelShould strive for both regularity and expressiveness due to the arbitrary data needs of consumers

There is no topic that generates more confusion in web development than the idea of Representational State Transfer,known as REST. This term comes from Chapter 5of Roy Fielding’s PhD thesis at U.C. Irvine.In this essay we will go through this Chapter and summarize the important concepts for non-academic web developers.

Fielding describes REST as an“architectural style for distributed hypermedia systems”, which sounds fancy but just means the web we all know and love:clicking on hyperlinks, submitting forms, looking at images, reading paragraphs and all that jazz.It was NOT created as a description of a particular approach for J

Locality of Behaviour (LoB)
</> htmx - high power tools for html
“The primary feature for easy maintenance is locality: Locality is that characteristic of source code that enables aprogrammer to understand that source by looking at only a small portion of it.” – Richard Gabriel#The LoB PrincipleLocality of Behaviour is the principle that:The behaviour of a unit of code should be as obvious as possible by looking only at that unit of code#DiscussionThe LoB principle is a simple prescriptive formulation of the quoted statement from Richard Gabriel.In as much as it is possible, and in balance with other concerns, developers should strive to make the behaviour ofa code element obvious on inspection.Consider two different implementations of an AJAX request in HTML, the first in htmx:<button hx-get="/clicked">Click Me</button>and the second in jQuery: $("#d1").on("click", function(){ $.ajax({ /* AJAX options... */ }); });<button id="d1">Click Me</button>In the former, the behaviour of the button element is obvious on inspection, satisfying the LoB princip

htmx 0.0.4 has been released!
</> htmx - high power tools for html
htmx 0.0.4 ReleaseI’m pleased to announce the 0.0.4 release of htmx, this time with noproject renaming.ChangesThis one had a lot of code clean up along with two major features:ExtensionsFirst off, htmx now has a proper extensions mechanism, allowing us to create extensions that plugin to the htmx life cycle and provide functionality that isn’t in the core library. Some extensions that have shippedwith this release and that you might find useful include:morphdom-swap - allows you to use the morphdom library for swapping in new contentclass-tools - replaces the retired hx-classes attributejson-enc - allows you to encode AJAX request bodies in JSONSee the full list of included extensions here.This extension mechanism will allow us to introduce useful HTML-oriented features while keeping the core htmx codefocused on loading content.Web Socket & Reworked Server Sent Events Supporthtmx now has experimental support for Web Socketswith the hx-ws attribute: <div hx-ws="connect wss:/chatroom"> <

kutty, er, htmx 0.0.3 has been released!
</> htmx - high power tools for html
htmx 0.0.3 ReleaseI’m pleased to announce the 0.0.3 release of kutty, er, htmx, the successorto intercooler.js!Why not kutty 0.0.2?One of the reasons you put a 0.0.1 release out there is to see what happens. And one of the things thathappened was that multiple people made comments on how the word “kutty” meant different things in different languages, including“small”, “child” and a very unfortunate meaning in dutch slang. I had originallycalled the project htmx(html extensions) and went back and forth between the two names for a bit.It seems like, upon contact with reality, htmx is a better long term name for the project. It’s alsoa lot easier to search twitter & reddit for that term.It’s a simple fix for anyone who actually used 0.0.1:attributes go from kt- to hx- (their original prefix)request headers go from X-KT- to X-HX-kutty goes to htmx for event names, etc.ChangesOK, so besides the big re-rename, what changed?A bug fix for the hx-prompt attributeA bug fix for multiple hx-swap-o

kutty 0.0.1 has been released!
</> htmx - high power tools for html
Kutty 0.0.1 ReleaseI’m pleased to announce the 0.0.1 release of kutty, the successorto intercooler.js!Like intercooler, kutty brings features of modern browsers that normally require javascript (AJAX, CSS transitions, etc.)directly into HTML.Why the rename?I chose to rename the project for a few reasons:I wanted the freedom to clean up mistakes and remove ideas that hadn’t worked out as cleanly as I wantedThe JS in intercooler.js implied a javascript-orientation. The more I developed intercooler the more I realizedthat it was really about enhancing (completing?) HTML, not javascript. This project doesn’t really compete with toolslike angular, vue or react, it’s something different, so I wanted a different name.kutty is short and memorable, kutty.org was available, and it has consonance with “cuttlefish” which is theofficial cephalopod of kutty development.So what’s new & different about kutty vs. intercooler?First and foremost, kutty has no external dependencies !No more dragging in jQ
