v3.0.0

Compare Source

Breaking

• Requires Node.js 22
• Removed built-in React support.
  • Add eslint-config-xo-react to your config instead. Learn more
  • It was removed to keep XO's core lean and framework-agnostic. Bundling eslint-plugin-react for everyone held XO back by its slow ESLint-major support, and there's now a competing plugin, @eslint-react, so picking one for all users no longer makes sense.
• The bundled rules now live in a single eslint-config-xo package. The separate eslint-config-xo-typescript package is merged into it.
  • If you prefer using ESLint directly, you can get all the rules there now.
• Replaced the xoToEslintConfig export with the xo/eslint-adapter import for editor/ESLint integration. For example, xoToEslintConfig([{space: true, prettier: true}]) becomes eslintConfigXo({space: true, prettier: true}) from eslint-config-xo, or simply export {default} from 'xo/eslint-adapter';.

Improvements

• Lint CSS, Markdown, HTML, JSDoc comments, and regular expressions out of the box
• Add --max-warnings flag to treat warnings as errors (#​724)
• Add ESLint bulk suppression support (#​826)
• Hide warnings when there are errors, so you can focus on what matters (#​507)
• Respect the global gitignore (#​803)
• Allow overriding default ignores with negation patterns (#​65)
• Throw when no files match explicitly provided patterns

v1.0.0

Compare Source

Breaking

• Requires ESLint flat config
• Requires Node.js 20.17
• Configuration now only through package.json and xo.config.{js,cjs,mjs,ts,cts,mts} files
• Switched from eslint-plugin-import to eslint-plugin-import-x (since it's better maintained)

  • --extend: Configurable via config file
  • --global: Configurable via config file
  • --extension: Configurable via config file
  • --env: No longer relevant with new config system
  • --node-version: Removed as it only affected unsupported Node.js versions
  • --reporter: Removed due to potential lookup reliability issues
• Node.js engines check removed
  • Was only active in unsupported Node.js versions
• Webpack lookup and import resolution removed
  • Considered too niche for core functionality

Improvements

• React support
• Prettier compatibility mode with {prettier: 'compat'} option
