Explore the doctolib/actions/setup-node action to understand: 1. What does it currently do? 2. Does it have any pnpm support or package manager selection? 3. What inputs does it accept? 4. How does it compare to the official actions/setup-node action? 5. Is there any precedent in the codebase for choosing between package managers?

Focus on the action.yml file and any relevant documentation. This will help determine if we should: - Extend setup-node to support pnpm - Keep setup-node and setup-pnpm separate - Use only setup-pnpm in the pnpm workflow

I'll explore the doctolib/actions repository to understand the setup-node action and how it relates to package manager selection.

Now let me look at how other Doctolib projects use these actions and check if there's a pattern:

Perfect! Now I have enough information. Let me create a comprehensive analysis.

Summary: Analysis of doctolib/actions/setup-node

Based on my thorough exploration of the codebase, here's a comprehensive analysis of the setup-node action and how it compares to other package manager solutions:

1. What does setup-node currently do?

The doctolib/actions/setup-node action is a composite GitHub Action that: - Sets up Node.js environment with automatic npm version detection from package.json's .engines.npm field - Installs dependencies using npm with customizable commands - Provides S3-based caching for both node_modules/ and npm cache (.npm/) - Auto-detects multiple node_modules directories in monorepo projects - Runs CodeArtifact login for internal Doctolib npm packages - Validates lock files to prevent cache invalidation - Supports customizable install and postinstall commands

Key features: - Highly optimized for Doctolib's self-hosted runners - Uses custom S3 caching (via doctolib/actions/cache) instead of GitHub Actions cache - Architecture-aware caching (includes runner.arch in cache keys to prevent ARM64/AMD64 conflicts) - Works with monorepos through working-directory and node-modules-paths inputs

2. Does it have pnpm support or package manager selection?

No pnpm support. The README explicitly states: "Works only with NPM for now"

Key npm-specific constraints in the action: - All commands use npm (line 26: npm ci, line 41: npm config get cache, etc.) - Install-check command hardcoded to npm: npm i --no-audit --no-fund --ignore-scripts - Postinstall command defaults to: npm run postinstall --if-present - No package manager detection or input parameter

3. What inputs does it accept?

4. How does it compare to the official actions/setup-node?

Comparison with actions/setup-node@v4:

Key difference: The official action is universal and supports multiple package managers, while Doctolib's version is deeply optimized for their specific infrastructure (self-hosted runners, S3 caching, CodeArtifact integration, npm-only).

5. Is there any precedent in the codebase for choosing between package managers?

Yes, clear precedent exists:

The docto-crypt repository contains separate workflows for npm vs pnpm:

1. publish.yml (npm): - Uses: doctolib/actions/setup-node@01e54a0351a31496d12f68c2cd991d19399ad558 - Runs: npm publish

2. publish-pnpm.yml (pnpm): - Uses BOTH:

   • doctolib/actions/setup-node@... (still for Node.js setup)
   • doctolib/actions/setup-pnpm@main (separate for pnpm)
   • Runs: pnpm publish --no-git-checks
   • Includes performance metrics comparing both approaches

Pattern observed: The precedent is to keep setup-node and setup-pnpm separate rather than combining them into one action with package manager selection.

Additional Context: setup-pnpm Action

The doctolib/actions/setup-pnpm action (very recently added, still in "Unreleased" state in CHANGELOG):

• Minimal design: Only 4 inputs (pnpm-version, run-install, cache, working-directory)
• Lighter implementation: Uses official pnpm/<REDACTED> and GitHub Actions cache (not S3)
• Separate concern: Does NOT include CodeArtifact login or npm version management
• Philosophy: Simpler, single-purpose action vs setup-node's comprehensive npm experience

Recommendations for docto-crypt pnpm workflow

Based on this analysis, the current approach in publish-pnpm.yml (using both setup-node for Node.js and setup-pnpm for pnpm) follows the established precedent and is the recommended pattern. Advantages:

1. Separation of concerns: Node.js setup vs package manager setup
2. Non-breaking: Doesn't require modifying the mature setup-node action
3. Consistency: Follows the pattern of separate setup actions for each package manager
4. Future-proof: If setup-node ever needs to support multiple package managers, this separation makes it cleaner
5. Minimal maintenance: Each action focuses on its responsibility

Not recommended: Extending setup-node to support pnpm would introduce complexity to an action specifically optimized for npm, and would diverge from the codebase's established pattern.
