@repobuddy/biome

@repobuddy/biome ships two Biome configs as JSONC files. Each one sets the formatter and the linter, so your biome.json only has to extend it.

Install

Section titled “Install”
Terminal window
# npm
npm install -D @repobuddy/biome @biomejs/biome


# yarn
yarn add -D @repobuddy/biome @biomejs/biome


# pnpm
pnpm add -D @repobuddy/biome @biomejs/biome

The package declares @biomejs/biome >= 2 as a peer dependency. Install Biome alongside it.

biome.json
{
  "extends": ["@repobuddy/biome"]
}

Biome @biomejs/biome >= 2 (peer dependency). Tested in this repository with 2.5.15. packages/biome/package.json
Config format JSONC files, exported as ., ./recommended, and ./performant. packages/biome/package.json
Module format Not applicable. The package contains no JavaScript. packages/biome/package.json (files)
File types Every file Biome processes, except **/.vscode/**/*.txt and **/*.md. recommended.jsonc, performant.jsonc
Formatter Tabs, lf, line width 120, single quotes, semicolons as needed. both configs

With the presets applied, Biome 2.5.15 picked up JavaScript, TypeScript, JSX/TSX, JSON, JSONC, CSS, GraphQL, Svelte, Vue, Astro, and HTML files in a scratch project. It ignored .yaml and .md files. What Biome supports is Biome’s decision; see the Biome documentation.

Not supported

Section titled “Not supported”
  • Biome 1.x. The peer range is >= 2, and the configs use Biome 2 keys (assist, files.includes).
  • Markdown. Both configs exclude **/*.md. Biome 2.5 does not process Markdown anyway, and the exclusion stays as a guard (see the comment in recommended.jsonc).
  • YAML linting. Biome does not process .yaml files, and the presets add nothing for them. This repository lints YAML with ESLint and eslint-plugin-yml (eslint.config.mjs).
  • Tuning for other tools. The presets do not configure ESLint, Prettier, or an editor.
