CI/CD for Monorepos
Explore strategies for optimizing CI/CD pipelines in monorepos, including selective job execution based on changed files.
What's a Monorepo?
A monorepo is a single repository that holds the code for many projects or applications. Instead of having separate repositories for each service or library, everything lives together.
Think of it like a big library with many books (projects) in one building (repository), rather than a separate building for each book. This approach has its pros and cons, especially for CI/CD.
Monorepo CI/CD Challenges
While monorepos offer benefits like easier code sharing, they can pose challenges for Continuous Integration/Continuous Delivery (CI/CD) pipelines:
- Slow Builds: If every change triggers a full build and test suite for *all* projects, pipelines become very slow.
- Resource Waste: Unnecessarily running unrelated jobs consumes build minutes and resources.
- Developer Frustration: Long feedback loops can slow down development velocity.
