## 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:

```json
{
  "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
