Define caching research

[BioPhoton]

What can be cached

• setup-env
  • npm workspace folder (.npmrc, package-lock.json, node_modules)
• npm-publish
  • inputs
  • build output, using dependent task output? careful though, it is known to struggle with Nx cloud agents
  • outputs
  • list of packages in registry under .../storage/.verdaccio-db.json e.g.: `{"list":[""],"secret":"esKM34zA53wetObgi5f0Uu1e7iObmm+f"}``
  • tarball of package under .../storage/@push-based/<package-name>-<version>.tgz e.g.: {workspaceRoot}/${environmentsDir}/{args.environmentProject}/storage/@push-based/${packageName},
  • package.json of package under .../storage/@push-based/<package-name>/package.json
• npm-install
  • outputs
  • list of installed packages under .../package.json
  • list of installed packages under .../package-lock.json
  • source of package under .../node_modules/@push-based/<package-name>/*
    mehh, we know the node_modules reputation
  • inputs:
  • output of npm-publish(?), package.json
  • concerns: chicken-egg problem.
  • when only caching package-lock.json, we still need to run <packageManager> install, separate install in 2 steps?
  • when caching node_modules, obviously cache takes lot of room!
  • to install dependencies and generate lock file, we need the Verdaccio server running

Caching scenarios

1. what can be cached?
2. is more small caches better
3. how to visualize scenarios

• what is a worse/best case for e2e tests
