turborepo-boundaries

Purpose

Enforces architectural boundaries between packages. Validates that import relationships respect configured rules about which packages can depend on which others.

Architecture

turborepo-boundaries
    ├── config/ - Boundary rules from turbo.json
    ├── tags/ - Package tag system for grouping
    ├── imports/ - Import location tracking
    └── Validation engine
        ├── Parse source files (swc)
        ├── Trace imports (turbo-trace)
        └── Check against rules

Rules can specify:

• Allowed/denied dependencies between tagged packages
• Per-package import restrictions

Notes

Uses swc for fast TypeScript/JavaScript parsing and turbo-trace for import resolution. Produces actionable error messages with source locations via miette.
