monorepo-management is a Claude Code skill for setting up and optimizing monorepos using Turborepo, Nx, and pnpm workspaces.

About

monorepo-management is a Claude Code skill for building and maintaining monorepos with Turborepo, Nx, and pnpm workspaces. A developer uses it to set up workspace structure, configure build pipelines and caching, manage shared dependencies with workspace filters, and wire CI/CD for multi-package repos. It provides concrete config examples for turbo.json, nx.json, and pnpm-workspace.yaml.

  • Sets up and optimizes monorepos with Turborepo, Nx, and pnpm workspaces
  • Covers turbo.json pipelines, workspace filtering, and shared package structure
  • Includes CI/CD and dependency-management strategies for multi-package repos

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)

Code Sharing Patterns

Pattern 1: Shared UI Components

// packages/ui/src/button.tsx
import * as React from 'react';

export interface ButtonProps {
  variant?: 'primary' | 'secondary';
  children: React.ReactNode;
  onClick?: () => void;
}

export function Button({ variant = 'primary', children, onClick }: ButtonProps) {
  return (
    <button
      className={`btn btn-${variant}`}
      onClick={onClick}
    >
      {children}
    </button>
  );
}

// packages/ui/src/index.ts
export { Button, type ButtonProps } from './button';
export { Input, type InputProps } from './input';

// apps/web/src/app.tsx
import { Button } from '@repo/ui';

export function App() {
  return <Button variant="primary">Click me</Button>;
}

Pattern 2: Shared Utilities

// packages/utils/src/string.ts
export function capitalize(str: string): string {
  return str.charAt(0).toUpperCase() + str.slice(1);
}

export function truncate(str: string, length: number): string {
  return str.length > length ? str.slice(0, length) + '...' : str;
}

// packages/utils/src/index.ts
export * from './string';
export * from './array';
export * from './date';

// Usage in apps
import { capitalize, truncate } from '@repo/utils';

Pattern 3: Shared Types

// packages/types/src/user.ts
export interface User {
  id: string;
  email: string;
  name: string;
  role: 'admin' | 'user';
}

export interface CreateUserInput {
  email: string;
  name: string;
  password: string;
}

// Used in both frontend and backend
import type { User, CreateUserInput } from '@repo/types';

Build Optimization

Turborepo Caching

// turbo.json
{
  "pipeline": {
    "build": {
      // Build depends on dependencies being built first
      "dependsOn": ["^build"],

      // Cache these outputs
      "outputs": ["dist/**", ".next/**"],

      // Cache based on these inputs (default: all files)
      "inputs": ["src/**/*.tsx", "src/**/*.ts", "package.json"]
    },
    "test": {
      // Run tests in parallel, don't depend on build
      "cache": true,
      "outputs": ["coverage/**"]
    }
  }
}

Remote Caching

# Turborepo Remote Cache (Vercel)
npx turbo login
npx turbo link

# Custom remote cache
# turbo.json
{
  "remoteCache": {
    "signature": true,
    "enabled": true
  }
}

CI/CD for Monorepos

GitHub Actions

# .github/workflows/ci.yml
name: CI

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v3
        with:
          fetch-depth: 0  # For Nx affected commands

      - uses: pnpm/action-setup@v2
        with:
          version: 8

      - uses: actions/setup-node@v3
        with:
          node-version: 18
          cache: 'pnpm'

      - name: Install dependencies
        run: pnpm install --frozen-lockfile

      - name: Build
        run: pnpm turbo run build

      - name: Test
        run: pnpm turbo run test

      - name: Lint
        run: pnpm turbo run lint

      - name: Type check
        run: pnpm turbo run type-check

Deploy Affected Only

# Deploy only changed apps
- name: Deploy affected apps
  run: |
    if pnpm nx affected:apps --base=origin/main --head=HEAD | grep -q "web"; then
      echo "Deploying web app"
      pnpm --filter web deploy
    fi

Best Practices

1. Consistent Versioning: Lock dependency versions across workspace 2. Shared Configs: Centralize ESLint, TypeScript, Prettier configs 3. Dependency Graph: Keep it acyclic, avoid circular dependencies 4. Cache Effectively: Configure inputs/outputs correctly 5. Type Safety: Share types between frontend/backend 6. Testing Strategy: Unit tests in packages, E2E in apps 7. Documentation: README in each package 8. 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
  uses: changesets/action@v1
  with:
    publish: pnpm release
  env:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
    NPM_TOKEN: ${{ secrets.NPM_TOKEN }}

FAQ

Which monorepo tools does it cover?

Package managers (pnpm, npm, Yarn workspaces) and build systems (Turborepo recommended for most, Nx, and Lerna in maintenance mode).

Does it help with CI/CD?

Yes, it covers setting up CI/CD for monorepos alongside build and test performance optimization.
