Biome

Biome is a unified, high-performance toolchain written in Rust that provides sub-millisecond code formatting and linting for JavaScript, TypeScript, and JSON.

When to Use

• Ultra-Fast Rust-Powered Linter & Formatter: Formatting and linting JavaScript, TypeScript, JSX, and JSON 25x faster than Prettier/ESLint.
• Unified Toolchain Setup: Replacing separate ESLint, Prettier, and import-sorter configs with a single biome.json.
• Instant CI Verification: Checking formatting, imports, and syntax in sub-seconds in automated CI pipelines.
• Prettier & ESLint Migration: Automated zero-friction migration using biome migrate.
