Nx: Gitlab CI build:affected caching

[florianeichin]

Description

We use Gitlab CI to build our applications and we evaluate nx for monorepo management.
Locally we had some promising results already.
Now we want to increase our buildtimes on the CI with the build affected.

Our setup is like the following:

• Lib A (Dependencies: None)
• Lib B (Dependencies: Lib A)
• Lib C (Dependencies: Lib A)
• App (Dependencies: Lib B, Lib C)

Locally we have to build every library once and can use nx affected:build afterwards. On the CI of course there are not all built libraries available. For this reason we get the following error: Some of the project lib-b's dependencies have not been built yet. Please build these libraries before: lib a
Of course this is logical as lib a was never built.

My question is how to handle that in gitlab ci, where to pull the dependencies from? Would it be a strategy to use Gitlabs cache for that?

Thanks in advance

There's a flag called --with-deps that will also build dependencies of the affected projects :smile:.

Hope that answers your question!

Thanks for the Reply, but no that doesn't really solves my problem. When building --with-deps I always build all the unerlying libs as well. So the lib A in this example would always run a build. As we have some base libs, that are almost never changed, we would build them a lot without need.
