Rules for enforcing import boundaries between packages and architectural layers.

Rules

Rule	Purpose
layer(target)	Enforce which imports a package or path-based layer may use

Usage

import { layer, Pure } from '@maat-tools/coupling-rules';

export default defineConfig({
	rules: [
		layer('@maat-tools/contracts').is(Pure).build(),
		layer('@maat-tools/kernel').allows('@maat-tools/contracts').build(),
		layer('src/domain/**').allows('src/shared/**', 'react').build(),
	],
});

Use package targets when your boundaries map to package names. Use path targets when your project is a single package with internal architectural layers.
