Generated biome.json

Why This Tool

Biome is a fast linter and formatter for JavaScript, TypeScript, JSON, and CSS. Configuring biome.json from scratch means reading through many options. This generator lets you visually select rules and outputs a valid config file.

How It Works

Choose your linting rules, formatter preferences (indent style, line width, quote style), and import organization settings. The tool generates a biome.json file you can drop into your project root.
