aj-geddes Monorepo Management
Table of Contents
Overview
Establish scalable monorepo structures that support multiple interdependent packages while maintaining build efficiency, dependency management, and deployment coordination.
When to Use
- Multi-package projects
- Shared libraries across services
- Microservices architecture
- Plugin-based systems
- Multi-app platforms (web + mobile)
- Workspace dependency management
- Scaled team development
Quick Start
Minimal working example:
{
"name": "monorepo-root",
"version": "1.0.0",
"private": true,
"workspaces": ["packages/*", "apps/*"],
"devDependencies": {
"lerna": "^7.0.0",
"turbo": "^1.10.0"
},
"scripts": {
"lint": "npm run lint -r",
"test": "npm run test -r",
"build": "npm run build -r",
"clean": "npm run clean -r"
}
}

Best Practices
✅ DO
- Use workspace protocols for dependencies
- Implement shared tsconfig for consistency
- Cache build outputs in CI/CD
- Filter packages in CI to avoid unnecessary builds
- Hoist common dependencies
- Document workspace structure
- Use consistent versioning strategy
- Implement pre-commit hooks across workspace
- Test cross-package dependencies
- Version packages independently when appropriate
❌ DON'T
- Create circular dependencies
- Use hardcoded versions for workspace packages
- Build all packages when only one changed
- Forget to update lock files
- Ignore workspace boundaries
- Create tightly coupled packages
- Skip dependency management
- Use different tooling per package
