ESLint Airbnb Extended is a modern ESLint configuration that builds on the widely used Airbnb style guide but upgrades it for today’s developer needs. It solves the biggest limitations of the original Airbnb config namely its lack of updates and incompatibility with ESLint v9 by providing a fully up-to-date, flat config–friendly, and one-to-one replacement for legacy Airbnb configs.

This config comes with built-in support for TypeScript, all necessary plugins and resolvers bundled internally, and customizable rules that enforce consistent, high-quality code across JavaScript and TypeScript projects.

To make setup even easier, a CLI utility (create-airbnb-x-config) guides you through installation, auto-detects your package manager, installs dependencies, and generates a tailored ESLint configuration for your codebase in seconds.

Because it’s designed for modern environments and active development, ESLint Airbnb Extended works seamlessly with the latest ESLint releases and helps teams maintain best practices without wrestling with outdated configs.
