@derived-modular/biome-plugin

Best-effort DMA rules for Biome (GritQL). Not a substitute for @derived-modular/cli (dma check).

Same four concerns as ESLint, but pattern-based — no import resolution, no @derived-modular/boundaries. Prefer @derived-modular/eslint-plugin when you can.

Architecture: DMA spec.

Install

npm install -D @derived-modular/biome-plugin

Usage

{
  "extends": ["@derived-modular/biome-plugin"]
}

Limitations

• Plugin paths resolve from the project root (./node_modules/@derived-modular/biome-plugin/...) — works with flat node_modules (npm/bun); fragile in some monorepo / PnP layouts until Biome improves shared-config plugin resolution.
• Heuristics only: @/ and relative path patterns, no full tsconfig alias support.
• No graph rules (no-cycle, inbound predicates).

Coverage

| Concern | Biome | ESLint | dma check | | --- | --- | --- | --- | | layer-direction | heuristic | yes | yes | | feature-to-feature | heuristic | yes | yes | | public-api | heuristic | yes | yes | | no-barrel | heuristic | yes | yes | | no-cycle / inbound | no | no | yes |
