Biome Has a Free API — One Tool to Lint, Format, and Fix JavaScript and TypeScript

#javascript #typescript #devtools #webdev

What if one tool replaced ESLint AND Prettier — running 35x faster because it is written in Rust?

Biome is a toolchain for JavaScript, TypeScript, JSON, CSS, and GraphQL. It handles linting, formatting, and import sorting in one pass.

Why Biome

  • 35x faster than ESLint + Prettier combined
  • One tool — no more ESLint + Prettier + eslint-config-prettier conflicts
  • Zero config — sensible defaults, works immediately
  • Import sorting — built in, no extra plugin
  • CSS and JSON — not just JS/TS
  • Editor integration — VS Code, JetBrains, Neovim

Quick Start 

npx @biomejs/biome init
Enter fullscreen mode Exit fullscreen mode 
# Format
npx biome format --write .

# Lint
npx biome lint .

# Both at once
npx biome check --write .
Enter fullscreen mode Exit fullscreen mode

biome.json 

{
  "formatter": {
    "indentStyle": "space",
    "indentWidth": 2
  },
  "linter": {
    "rules": {
      "complexity": { "noForEach": "warn" },
      "suspicious": { "noExplicitAny": "error" }
    }
  },
  "organizeImports": { "enabled": true }
}
Enter fullscreen mode Exit fullscreen mode

Migration from ESLint + Prettier 

npx @biomejs/biome migrate eslint --write
npx @biomejs/biome migrate prettier --write
Enter fullscreen mode Exit fullscreen mode

Biome reads your existing ESLint and Prettier configs and converts them.

Real Use Case

A monorepo had ESLint taking 45 seconds in CI — with 15 plugins, each adding startup time. After migrating to Biome, the same lint + format ran in 1.2 seconds. CI pipeline time dropped by 2 minutes per commit. Developers stopped disabling lint checks because they were no longer slow.

When to Use Biome

  • Any JavaScript/TypeScript project
  • Replacing ESLint + Prettier setup
  • Monorepos where lint speed matters
  • Teams wanting simpler tooling config
