# Popular ESLint Plugins — ESLint + Prettier

Source: https://www.geekswithgeeks.com/en/eslint-prettier/eslint-prettier-07

> Extend ESLint with plugins for React, Vue, TypeScript, and more.

## 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 for React projects.

```bash
npm install --save-dev eslint-plugin-react
# In .eslintrc.json:
{
  "extends": ["eslint:recommended", "plugin:react/recommended"],
  "plugins": ["react"],
  "rules": { "react/prop-types": "warn" }
}
```

Output:

```
React plugin installed and configured
```

## Plugin ecosystem

Popular plugins include eslint-plugin-import (imports), eslint-plugin-jsx-a11y (accessibility), and eslint-plugin-node. Each adds rules relevant to its domain.
