Monorepo Management
Build efficient, scalable monorepos that enable code sharing, consistent tooling, and atomic changes across multiple packages and applications.
When to Use This Skill
Setting up new monorepo projects
Migrating from multi-repo to monorepo
Optimizing build and test performance
Managing shared dependencies
Implementing code sharing strategies
Setting up CI/CD for monorepos
Versioning and publishing packages
Debugging monorepo-specific issues
Core Concepts
1. Why Monorepos?
Advantages:
Shared code and dependencies
Atomic commits across projects
Consistent tooling and standards
Easier refactoring
Simplified dependency management
Better code visibility
Challenges:
Build performance at scale
CI/CD complexity
Access control
Large Git repository
2. Monorepo Tools
Package Managers:
pnpm workspaces (recommended)
npm workspaces
Yarn workspaces
Build Systems:
Turborepo (recommended for most)
Nx (feature-rich, complex)
Lerna (older, maintenance mode)
Turborepo Setup
Initial Setup # Create new monorepo
npx create-turbo@latest my-monorepo
cd my-monorepo
# Structure:
# apps/
# web/ - Next.js app
# docs/ - Documentation site
# packages/
# ui/ - Shared UI components
# config/ - Shared configurations
# tsconfig/ - Shared TypeScript configs
# turbo.json - Turborepo configuration
# package.json - Root package.json
Configuration // turbo.json

Detailed patterns and worked examples Detailed pattern documentation lives in references/details.md. Read that file when the navigation tier above is insufficient.
Best Practices
Consistent Versioning : Lock dependency versions across workspace
Shared Configs : Centralize ESLint, TypeScript, Prettier configs
Dependency Graph : Keep it acyclic, avoid circular dependencies
Cache Effectively : Configure inputs/outputs correctly
Type Safety : Share types between frontend/backend
Testing Strategy : Unit tests in packages, E2E in apps
Documentation : README in each package
Release Strategy : Use changesets for versioning
Common Pitfalls
Circular Dependencies : A depends on B, B depends on A
Phantom Dependencies : Using deps not in package.json
Incorrect Cache Inputs : Missing files in Turborepo inputs
Over-Sharing : Sharing code that should be separate
Under-Sharing : Duplicating code across packages
Large Monorepos : Without proper tooling, builds slow down
Publishing Packages # Using Changesets
pnpm add -Dw @changesets/cli
pnpm changeset init
# Create changeset
pnpm changeset
# Version packages
pnpm changeset version
# Publish
pnpm changeset publish
# .github/workflows/release.yml
- name: Create Release Pull Request or Publish
