Hi,

In the Azure Devops guide, the cache operation includes pnpm-lock.yaml:

steps:
  - task: Cache@2
    inputs:
      key: 'pnpm | "$(Agent.OS)" | pnpm-lock.yaml'
      path: $(pnpm_config_cache)
    displayName: Cache pnpm

As far as I understand, the cache will be invalidated everytime the lock file changes.

That means the whole store will be redownloaded again if a single package in the whole tree changes. Which is very frequent.

Because pnpm is smart enough to download only missing packages, shouldn't pnpm-lock.yaml be removed from the input keys of the cache operation ?

If wasting space is a concern, maybe a simple call to pnpm store prune after the pnpm install command may be enough?
