Biome shared configuration

Shared Biome formatter and linter settings.

Usage

Add a biome.json (or biome.jsonc) that extends the default preset:

{
  "$schema": "https://biomejs.dev/schemas/2.3.10/schema.json",
  "extends": ["@kcconfigs/biome"]
}

The default preset extends the base rules and excludes generated artifacts such as dist, coverage, and test reports. See biome.default.json for the full list.

Variants

• @kcconfigs/biome: extends the base preset and adds sensible file includes/excludes plus editorconfig awareness.
• @kcconfigs/biome/base: bare preset containing formatter, linter, and assist rules without workspace-specific file filters; useful if you want custom include/exclude patterns.

Example using the base preset with custom overrides:

{
  "$schema": "https://biomejs.dev/schemas/2.3.10/schema.json",
  "extends": ["@kcconfigs/biome/base"],
  "files": { "includes": ["src/**/*.ts", "tests/**/*.ts"] },
  "linter": {
    "rules": {
      "complexity": {
        "noUselessSwitchCase": "warn"
      }
    }
  }
}
