#monorepo

Manage codebase in monorepo. Tools: 1. Turborepo (fast task execution, caching). 2. Nx (powerful CLI, generators). 3. Lerna (package management, versioning). 4. pnpm workspaces (efficient dependencies). 5. Rush (large-scale enterprise). Benefits: Shared code, atomic changes, consistent versioning. Challenges: Build times, tooling complexity. Use build caching and affected commands. Implement code ownership.

Set up a Turborepo monorepo with shared components. Structure: 1. apps/ folder for Next.js and React apps. 2. packages/ui for shared component library. 3. packages/config for shared configs (ESLint, TS). 4. Parallel task execution with turbo run. 5. Remote caching for CI/CD speed. 6. Versioning with changesets. 7. Storybook for component documentation. 8. Testing with Vitest across packages. Use pnpm workspaces and implement proper dependency graphs.
