Monorepo Structure

One repo, multiple packages, shared types, parallel builds.

When to Use This Skill

• Sharing code between frontend and backend
• Multiple apps need common types/utilities
• Want atomic commits across packages
• Tired of version hell with separate repos
• Need parallel builds with caching

Core Concepts

1. Workspaces - pnpm manages multiple packages in one repo
2. Turborepo - Orchestrates builds with caching and parallelization
3. Shared types - Single source of truth for TypeScript types
4. Build order - Dependencies build before dependents
