Prettier integration

A new prettier option lets you combine the rules with Prettier:

export default defineConfig([
	...eslintConfigXo({prettier: true}),
]);

• true — Runs Prettier as an ESLint rule using XO's Prettier style, and disables the stylistic rules that would conflict with it. Requires prettier to be installed.
• 'compat' — Only disables the stylistic rules that conflict with Prettier, for when you run Prettier separately (for example, from your editor).

Anything XO does not configure (like printWidth or Prettier plugins) still respects your .prettierrc, but XO's own style settings take precedence. prettier is an optional peer dependency.

CSS linting

.css files are now linted out of the box via @eslint/css: duplicate imports, empty blocks, invalid at-rules, unmatchable selectors, invalid named grid areas, and more.

v0.51.0

Compare Source

Breaking

• The package now exports a function instead of an array. Update your eslint.config.js:

-export default eslintConfigXo;
+export default [...eslintConfigXo()];

• Removed the ./space and ./browser sub-path exports. Use the space and browser options instead:

export default [...eslintConfigXo({space: true, browser: true})];

• Requires ESLint 10 and Node.js 20.19+.

Improvements

• Merged eslint-config-xo-typescript: TypeScript rules are now included. No need to install a separate package.
• Merged plugin configs from XO: Includes eslint-plugin-unicorn, eslint-plugin-import-x, eslint-plugin-n, eslint-plugin-ava, @eslint-community/eslint-plugin-eslint-comments, and a built-in no-use-extend-native rule. Previously these were only available through the XO CLI.
• Added semicolon option
• Added TypeScript declaration file
• Add no-shadow rule 4cec7d2
