Monorepo vs Multiple Repos: Which is Better for My Project?

What are the main differences between using a monorepo and multiple repos?

A monorepo is a single repository that contains multiple projects, while multiple repos have each project in its own repository. Monorepos can simplify dependency management and code sharing, but may become unwieldy as projects grow. Multiple repos offer better isolation but can complicate dependency management.

What are the advantages of using a monorepo?

Some advantages of a monorepo include easier code sharing, consistent tooling across projects, and simplified dependency management. It also allows for atomic commits across projects, making it easier to maintain compatibility.

Are there any downsides to using a monorepo?

Yes, downsides include potential performance issues with large repositories, complex build processes, and challenges in managing access control for different teams.

When should I consider using multiple repos instead?

Consider using multiple repos if your projects are highly independent, require different lifecycles, or if you need strict access control for different teams.

Can you give examples of companies that use monorepos?

Sure! Companies like Google, Facebook, and Twitter use monorepos to manage their large codebases effectively.
