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
