Best Practices
Structure:
✓ Separate apps and packages
✓ Share configs as packages
✓ Use workspace protocol
✓ Keep packages focused
Performance:
✓ Enable remote caching
✓ Configure proper outputs
✓ Use incremental builds
✓ Parallelize where possible
Dependencies:
✓ Hoist common dependencies
✓ Version shared packages together
✓ Document breaking changes
✓ Test cross-package changes
Conclusion
Turborepo makes monorepos efficient with intelligent caching and parallel execution. Structure apps and packages clearly, share configurations, and leverage remote caching for CI/CD. The initial setup investment pays off with improved code sharing and build performance.
