ESLint React

A series of composable ESLint Plugins for libraries and frameworks that use React as a UI runtime.

Features

• Modern: First-class support for TypeScript, React 19, and more.
• Flexible: Increased flexibility with more granular severity control.
• Performant: Built with performance in mind, optimized for large codebases.
• Comprehensive: Handles complex scenarios and identifies problems that other tools might miss.

Modular

• eslint-plugin-react-x - Core rules (renderer-agnostic, compatible with x-platform).
