      • Getting Started

      Prerequisites

      • Biome 2.5 or later
      • pnpm 10 or later (or npm / yarn)

      Installation

      pnpm add -D @logue/biome-plugins

      Configuration

      Register the rules you want in your biome.jsonc:

      {
  "$schema": "https://biomejs.dev/schemas/2.5.9/schema.json",
  "plugins": [
    {
      "path": "./node_modules/@logue/biome-plugins/grit/enforce-pure-src.grit",
    },
    {
      "path": "./node_modules/@logue/biome-plugins/grit/prefer-union-over-enum.grit",
    },
    {
      "path": "./node_modules/@logue/biome-plugins/grit/no-null-type.grit",
    },
  ],
}

      Verify

      Run Biome to confirm the rules are active:

      pnpm biome lint .

      Write a deliberate violation and check that a diagnostic appears:

      // should trigger prefer-union-over-enum → error
enum Color {
  Red = "red",
}

      Selective Loading

      You can load only the rules you need. Each .grit file is independent:

      {
  "plugins": [
    // Load only the enum rule
    {
      "path": "./node_modules/@logue/biome-plugins/grit/prefer-union-over-enum.grit",
    },
  ],
}
