Cracking the Python Monorepo

3 days ago

A monorepo is a single repository containing multiple projects, used by large companies like Google and Facebook.
Monorepos solve the problem of local dependencies between projects, ensuring compatibility and reducing technical debt.
Challenges of monorepos include slow CI/CD pipelines and complex dependency management.
Modern tooling like `uv` and `Dagger` simplifies Python monorepo setup and maintenance.
`uv` provides workspace support for managing dependencies in monorepos efficiently.
`Dagger` enables modular and cached build pipelines, improving performance.
The approach outlined allows for granular copying of source code and efficient caching.
Downstream steps like testing (`pytest`) and type checking (`pyright`) can be integrated seamlessly.
Combining `uv` and `Dagger` results in a flexible, high-performance build process for Python monorepos.
