HighlightsFive core rules now highlight smaller ranges of code to avoid shadowing other problems in editors.Rules max-lines-per-function, max-nested-callbacks, and max-statements now highlight only the function header instead of the entire function.Rules max-depth and no-with now highlight only the first keyword.Several errors in the calculations have been corrected in the max-depth and max-nested-callbacks rules. These bug fixes can result in reporting more linting errors in existing code.Features5ca8c52 feat: correct stack tracking in max-nested-callbacks (#20973) (Pixel998)b565783 feat: report no-with violations at the with keyword (#20971) (Pixel998)2ce032f feat: report max-lines-per-function violations at function head (#20966) (Pixel998)732cb3e feat: report max-nested-callbacks violations at function head (#20967) (Pixel998)f9c138a feat: report max-depth violations on keywords (#20943) (Pixel998)bdb496c feat: correct max-depth handling for else-if chains (#20944) (Pixel998)c29687

HighlightsNew includeIgnoreFile() helperThis release introduces the includeIgnoreFile() helper for configuration files that allows for including patterns from .gitignore files or any other files with gitignore-style patterns.Previously available in the external package @eslint/compat, the new includeIgnoreFile helper function is exported from the eslint/config entrypoint and provides an extended API that allows multiple files to be included and patterns to be interpreted relative to the location of those files, which is a common use case for nested .gitignore files.// eslint.config.jsimport { defineConfig, includeIgnoreFile } from "eslint/config";import { fileURLToPath } from "node:url";const rootGitignorePath = fileURLToPath( new URL(".gitignore", import.meta.url));const nestedGitignorePath = fileURLToPath( new URL("some/other/folder/.gitignore", import.meta.url),);export default defineConfig([ includeIgnoreFile([rootGitignorePath, nestedGitignorePath], { // option to interpret patter

Highlightsno-unused-private-class-members SuggestionsThe no-unused-private-class-members rule now provides suggestions to remove reported unused private class members.For example, for the following code, in which the rule reports #doSomethingElse as unused:class C { /** * My public method. */ doSomething() { } /** * My private method. */ #doSomethingElse() { }}12345678910111213141516Copy code to clipboard It will now suggest removing #doSomethingElse.

HighlightsLanguage-aware rulesESLint v10.2.0 adds support for language-aware rules through the new meta.languages property. Rule authors can now explicitly declare which languages a rule supports, and ESLint will throw a runtime error if that rule is enabled for an unsupported language, as specified by the language configuration option.Here is an example of a rule that only supports the JavaScript language:const rule = { meta: { type: "problem", docs: { description: "Example JavaScript rule", }, languages: ["js/js"], }, create(context) { return {}; },};123456789101112Copy code to clipboard Currently, none of the ESLint built-in rules restrict the languages they are designed to work with, but this may change in the future.More information about the meta.languages property can be found in the custom rules documentation.Temporal supportWith the Temporal proposal now at TC39 stage 4, ESLint v10.2.0 recognizes Temporal as a built-in global. As a result, the no-undef rule no longer flags Tem

HighlightsAPI Support for Bulk SuppressionsESLint v10.1.0 introduces API support for the bulk suppressions feature that was previously only available in the CLI.ESLint API consumers, such as IDEs, can now pass the applySuppressions: true option to the ESLint constructor. With this option, suppressions from the suppressions file are automatically applied to results from ESLint#lintFiles() and ESLint#lintText() methods.const eslint = new ESLint({ applySuppressions: true, // optional, defaults to `eslint-suppressions.json` suppressionsLocation: "./config/my-suppressions.json",});123456Copy code to clipboard Please see the Bulk Suppressions - Usage with the Node.js API section for more details.Featuresff4382b feat: apply fix for no-var in TSModuleBlock (#20638) (Tanuj Kanti)0916995 feat: Implement api support for bulk-suppressions (#20565) (Blake Sager)Bug Fixes2b8824e fix: Prevent no-var autofix when a variable is used before declaration (#20464) (Amaresh S M)e58b4bf fix: update eslint (#
