Biome

Biome is a high-performance toolchain designed to format and lint your web projects in a fraction of a second. Built in Rust, it offers a significant speed advantage, claiming to be over 35x faster than Prettier when handling large codebases. It provides robust support for a wide range of languages including JavaScript, TypeScript, JSX, CSS, HTML, and GraphQL.

The formatter can handle malformed code as you type, while the linter incorporates hundreds of rules from tools like ESLint and TypeScript ESLint. A key feature is its ability to provide detailed and contextualized diagnostics, helping you fix issues and learn best practices. You can run formatting and linting separately or together with a single check command, creating a cohesive and efficient workflow for any size project.
