ESLint Config Generator

What is ESLint Config Generator?

ESLint Config Generator creates customized .eslintrc configuration files based on your project type, framework, and code style preferences. It generates configs for modern flat config format (eslint.config.js) and legacy formats (.eslintrc.json, .eslintrc.yml), incorporating popular presets like Airbnb, Standard, and Google style guides. The tool detects framework needs (React, Vue, Angular, Next.js) and includes appropriate parser plugins, and generates the corresponding npm install command for all required dependencies.

Frontend developers setting up new projects, tech leads standardizing code style across teams, and open-source maintainers configuring contribution guidelines. The tool runs entirely in your browser — your data never leaves your device.

How to Use ESLint Config Generator

1. Select your project type — JavaScript or TypeScript, and the framework (React, Vue, Node.js, etc.)
2. Choose a base style guide (Airbnb, Standard, Google) or start with recommended defaults
3. Customize specific rules — toggle semicolons, quote style, indentation, trailing commas, etc.
4. Copy the generated config file and the npm install command to set up ESLint in your project

Common Use Cases

• Setting up ESLint for a new TypeScript React project with Airbnb style guide rules
• Migrating from legacy .eslintrc to the new flat config format in ESLint 9+
• Creating a shared ESLint config for consistent code style across multiple team repositories
• Configuring ESLint for a monorepo with different rules for frontend and backend packages

Pro Tips

• ESLint 9 uses flat config (eslint.config.js) by default — the legacy .eslintrc format still works but is officially deprecated; new projects should use flat config from the start
• The TypeScript parser (@typescript-eslint/parser) adds 2-3 seconds to lint time because it builds a full type-checked AST — for faster IDE feedback, disable type-aware rules and run them only in CI
• Airbnb config is the most popular but also the strictest — if your team constantly disables rules, consider Standard style (no semicolons, less opinionated) to reduce .eslintrc overrides
