What to cache for CI using the PnP linker?

[jmariller]

The question was already asked for the node_modules linker here, but I am wondering what would be the proper setup when using the Plug'n'Play linker?

Right now I have one job to compile my assets, and another job to run tests with Jest. I have committed my .yarn/.cache folder, and tried to cache the full .yarn folder. Now when running the tests job I have to first run anyhow yarn install, otherwise jest cannot be found. Any ideas/suggestions?

Given that you are using pnp and zero installs, you would also need to commit yarn.lock, .pnp.cjs, and .pnp.loader.mjs (I think that is what it’s called)
