Real-world Project Examples

Reference implementations

React projects, Node.js backends, TypeScript monorepos—each has unique linting needs. Review examples to adapt for your context.

React project setup

A complete ESLint and Prettier setup for a modern React project.

// .eslintrc.json for React project
{
  "env": { "browser": true, "es2021": true },
  "extends": ["eslint:recommended", "plugin:react/recommended", "prettier"],
  "plugins": ["react", "react-hooks"],
  "rules": {
    "react/react-in-jsx-scope": "off",
    "react-hooks/rules-of-hooks": "error",
    "no-unused-vars": "warn"
  }
}

// .prettierrc
{
  "singleQuote": true,
  "trailingComma": "es5",
  "semi": true
}

Output:

React project ready for linting and formatting
