| description | Configure and operate BiomeJS in JavaScript/TypeScript projects, including installation, `biome.json` setup, formatter/linter/check workflows, VCS integration, and CI usage. Use when users ask to adopt Biome, tune rules/includes, set up monorepo/shared configs, or troubleshoot Biome command behavior. |
BiomeJS
Use this skill to implement and operate BiomeJS with predictable steps and minimal disruption.
For ESLint/Prettier migration, use the dedicated eslint-prettier-migration skill.
Workflow
- Identify intent:
- Fresh setup
- Config tuning
- CI/VCS integration
- Diagnostics troubleshooting
- Apply the matching path:
- Fresh setup: follow
references/getting-started.md
- Config and file-scoping: follow
references/configuration-and-vcs.md
- Advanced config templates: follow
references/advanced-configuration-templates.md
- CLI options/reporters: follow
references/cli-basics.md
- Monorepo and shared config strategy: follow
references/monorepo-and-upgrades.md
- Performance debugging: follow
references/performance-tracing.md
- Pre-commit hooks and CI recipes: follow
references/automation-ci-and-hooks.md
- Verify with a no-write pass before auto-fixing:
- Run
biome check .
- Then run
biome check --write only after confirming scope and intended changes
Operational Defaults
Use these defaults unless user asks otherwise:
- Pin Biome version when installing (
-E with package managers that support it).
- Keep config in project root (
biome.json or biome.jsonc).
- Run
biome check --write for unified format+lint+organize imports.
- Run
biome ci in CI pipelines.
