pnpm/action-setup Cache Migration

1. Inspect Workflow Files

1. Open the target .github/workflows/*.yml or .yaml files.
2. Locate steps using pnpm/action-setup.
3. Record the current uses: pnpm/action-setup@... version.
4. Check whether caching is configured with either:
   • actions/setup-node using cache: pnpm, or
   • actions/cache targeting pnpm store directories.

2. Upgrade pnpm/action-setup and Enable Built-in Cache

1. If pnpm/action-setup is older than v4.3.0, update it to a modern tag (v4.3.0 or newer).
2. Ensure the action input enables built-in caching:

- uses: pnpm/[email protected]
  with:
    cache: true

3. Keep existing version (pnpm CLI version) or other unrelated inputs unless the user explicitly asks to change them.

3. Remove Legacy pnpm Cache Configuration

1. Remove pnpm cache wiring from actions/setup-node steps:
   • delete cache: pnpm
   • delete cache-dependency-path values that were only used for pnpm caching
2. Remove dedicated actions/cache steps that cache pnpm store directories (for example paths from pnpm store path or ~/.pnpm-store).
3. Preserve non-pnpm caches and unrelated setup-node behavior (Node version selection, registry config, auth).

4. Validate Final Workflow Shape

1. Confirm each pnpm workflow now has exactly one cache strategy for pnpm: pnpm/action-setup with cache: true.
2. Confirm no leftover pnpm-specific cache keys or paths remain in actions/setup-node or actions/cache steps.
3. Keep edits minimal and avoid unrelated workflow churn.

Example Migration

Before:

- uses: pnpm/[email protected]
- uses: actions/setup-node@v4
  with:
    node-version-file: .nvmrc
    cache: pnpm

After:

- uses: pnpm/[email protected]
  with:
    cache: true
- uses: actions/setup-node@v4
  with:
    node-version-file: .nvmrc
