Polyrepo to Monorepo Migration
Consolidate multiple repositories into a unified monorepo for better code sharing, consistency, and developer experience.
Who This Is For
Ideal for organizations managing multiple related applications or libraries across separate repositories, experiencing difficulties with code sharing, version synchronization, or cross-project refactoring. If you're spending too much time managing dependencies and keeping projects in sync, a monorepo can help.
Typical Problems I Solve
- Duplicated code and utilities across multiple repositories
- Difficult to make atomic changes across multiple projects
- Version management nightmares with interdependent packages
- Inconsistent tooling and development practices across teams
- Complex CI/CD setup for multiple repositories
- Time-consuming code reviews spanning multiple repositories
My Approach
Analyze your current repository structure and identify dependencies
Design monorepo structure with optimal workspace organization
Select and configure monorepo tooling (Nx, Turborepo, or custom)
Migrate codebases incrementally with git history preservation
Establish shared libraries and component patterns
Configure unified CI/CD pipelines with intelligent caching
What You Get
- Comprehensive migration plan with risk assessment
- Configured monorepo with optimized workspace structure
- Migrated applications and libraries with preserved git history
- Shared library architecture and component catalog
- Unified build, test, and deployment pipelines
- Development workflow documentation and best practices
- Performance-optimized CI/CD with task caching
- Team training on monorepo workflows and tooling
How We Work Together
Polyrepo to monorepo migrations typically take 4-8 weeks depending on the number of repositories and complexity. I work collaboratively with your team, ensuring minimal disruption to ongoing development. We can phase the migration or do a complete cutover based on your needs.
Frequently Asked Questions
Which monorepo tool do you recommend?
It depends on your needs. Nx is excellent for Angular projects with powerful caching and generators. Turborepo offers simplicity and speed. I assess your requirements and recommend the best fit.
Can we keep our git history?
Yes, git history preservation is a priority. I use specialized tools and techniques to maintain commit history, blame information, and contributor data during migration.
How do you handle different technology stacks?
Modern monorepo tools support polyglot repositories. I configure appropriate build tools for each technology while maintaining unified developer experience.
What about our CI/CD pipelines?
I redesign CI/CD to be monorepo-aware, implementing intelligent caching and affected-only builds. This often results in faster builds than the original polyrepo setup.
Is a monorepo right for us?
Monorepos work best for related projects with shared code. During assessment, I evaluate if a monorepo fits your organization or if alternatives like better dependency management make more sense.
