+[ESLint](https://eslint.org/) is a linter for JavaScript, TypeScript, JSX, TSX, CSS, etc.

+## Files

+ESLint will run on files with the following extensions:
+
+- `.js`

+- `.d.mts`
+- `.jsx`

+## Configuration
+
+CodeRabbit reads your ESLint configuration and uses it as is. Please ensure that all ESLint dependencies are defined in your `package.json` file(s). CodeRabbit supports Yarn and PNPM workspaces in your monorepo. CodeRabbit doesn't support private ESLint plugins or configurations at the moment.
