v0.51.0

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
