Popular ESLint Plugins

What plugins do

Plugins add domain-specific rules. eslint-plugin-react checks JSX, eslint-plugin-vue checks Vue templates. Install and enable them to catch framework-specific errors.

Using React plugin

Install and configure eslint-plugin-react in a flat config.

npm install --save-dev eslint-plugin-react

// eslint.config.js
import react from 'eslint-plugin-react';

export default [
  react.configs.flat.recommended,
  {
    files: ['**/*.{jsx,tsx}'],
    settings: { react: { version: 'detect' } },
    rules: { 'react/prop-types': 'warn' },
  },
];

Output:
