# ESLint Configuration for React Projects

ESLint helps identify and fix problems in your JavaScript code.

Sample .eslintrc.js Configuration

module.exports = {
  env: {
    browser: true,
    es2021: true,
  },
  extends: [
    'eslint:recommended',
    'plugin:react/recommended',
    'plugin:react-hooks/recommended',
  ],
  parserOptions: {
    ecmaFeatures: {
      jsx: true,
    },
    ecmaVersion: 12,
    sourceType: 'module',
  },
  plugins: ['react', 'react-hooks'],
  rules: {
    'react/react-in-jsx-scope': 'off',
    'react/prop-types': 'warn',
    'react-hooks/rules-of-hooks': 'error',
    'react-hooks/exhaustive-deps': 'warn',
  },
};

Key Configuration Options

• env: Specifies the environments your code is designed to run in
• extends: Inherits configurations from recommended ESLint and React rules
• parserOptions: Specifies the JavaScript language options
• plugins: Adds support for React-specific linting rules
• rules: Customizes individual linting rules

Installation

Ensure you have the necessary dependencies installed:

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

Place this configuration in a .eslintrc.js file at the root of your project.
