Biome Linter & Formatter

Set up Biome as a unified linter and formatter — 56x faster than ESLint + Prettier. Configures rules, migrates from existing setups, integrates with CI/CD, and handles project-wide code quality enforcement.

This skill helps you adopt Biome, the Rust-powered linter and formatter that replaces ESLint and Prettier in a single tool. It migrates existing configs, sets up custom rule configurations, configures IDE integration, adds pre-commit hooks, and integrates with CI pipelines.

When to use

Use when setting up code quality for a new project, migrating from ESLint/Prettier for faster CI, standardizing formatting across a team, or reducing toolchain complexity.

Examples

Migrate from ESLint + Prettier

Replace ESLint and Prettier with Biome

Migrate our project from ESLint + Prettier to Biome — convert existing rules, update CI, and set up VS Code integration

Custom rule configuration

Configure Biome rules for team standards

Set up Biome with our team's coding standards — enforce no-any, require explicit return types, ban console.log in production
