Biome (formerly Rome) is a unified toolchain. It replaces Prettier and ESLint. v2.0 (2025) adds a plugin system (GritQL) and multi-file analysis.

When to Use

  • Greenfield Projects: Start with Biome for instant linting/formatting.
  • CI Speed: It lints a monorepo in milliseconds.
  • Simplicity: One config file biome.json.

Core Concepts

Formatter

97% compatibility with Prettier.

Linter

100+ rules. fast, informative diagnostics.

Analyzer

Understands import graphs (unlike ESLint which mostly checks single files).

Best Practices (2025)

Do:

  • Migrate: Use biome migrate to import Prettier/ESLint configs.
  • Use Editor Extension: The VS Code extension is extremely fast.

Don't:

  • Don't mix with Prettier: Pick one.
