Biome Has a Free Linter and Formatter — Replace ESLint and Prettier with One Tool

#typescript #opensource #javascript #devops

A developer had ESLint (200+ rules), Prettier (formatting), eslint-config-prettier (resolving conflicts between them), and 15 ESLint plugins. Config files totaled 300 lines.

Biome is a single tool that replaces ESLint AND Prettier. Written in Rust, it is 35x faster. One config file. Zero plugin hell.

What Biome Offers for Free

  • Linting - 270+ rules (covers most ESLint rules)
  • Formatting - Prettier-compatible output
  • One Tool - No more ESLint vs Prettier conflicts
  • 35x Faster - Written in Rust
  • Zero Config - Works out of the box
  • Import Sorting - Built-in import organization
  • TypeScript - First-class TS support
  • JSX/TSX - React and framework support
  • CI-Friendly - biome ci for CI pipelines
