What is Biome Config Generator?
The Biome Config Generator builds a valid Biome v2 biome.json through a visual form: formatter options (indent, line width, quotes, semicolons), linter recommended rules, assist actions, and git VCS integration - with the JSON regenerated live and one-click copy.
Key Benefits
- No schema memorization - pick options and copy the file
- Sections stay minimal because disabled parts are omitted
- VCS and assist integration covered, not just formatting
- Great starting point for migrating from ESLint + Prettier
Common Use Cases
- •Setting up Biome in a new JavaScript or TypeScript project
- •Standardizing one shared biome.json across repositories
- •Migrating teams from separate ESLint and Prettier configs
- •Onboarding contributors with a documented team style
- •Trying different formatter settings before committing one
Generate a Biome Config
- Set formatter options: Choose indent style and width, line width, quote style, and semicolon behavior - or disable the formatter if another tool owns formatting.
- Tune the linter: Keep the linter enabled with recommended rules, or disable it if ESLint remains the linter of record.
- Wire up assist and VCS: Enable assist actions and, if you use git, turn on VCS integration so Biome can respect your .gitignore.
- Copy biome.json: Copy the generated JSON into biome.json at your project root and run npx @biomejs/biome check to verify.
