What does it use for Node.js installation? (actions/setup-node or custom logic?)\n2. What Node.js-specific configurations does it apply?\n3. What Doctolib-specific infrastructure does it set up (S3, CodeArtifact, etc.)?\n4. Could those Doctolib-specific parts benefit pnpm workflows even without npm?\n\nAlso check:\n- Does setup-node do anything besides Node.js + npm setup that would benefit all Node-based workflows?\n- Are there any environment variables, registry configs, or authentication setups that pnpm would need?\n\nThis will help determine if extending setup-pnpm to include Node.js installation (but skip npm) is viable and beneficial.\n\nFile to focus on: /Users/USER/workspace/doctolib/actions/setup-node/action.yml\n\nTurn 1 — Assistant\n\nI'll help you explore how doctolib/actions/setup-node installs Node.js and its configurations.

Now I have a comprehensive view. Let me create a detailed analysis report.\n\nAnalysis Report: doctolib/actions/setup-node Installation and Configuration\n\n1. Node.js Installation Method\n\nUses: actions/setup-node (GitHub's official action, v4)\n- Step at line 110-117 of action.yml\n- Implementation: uses: actions/setup-node@49933ea5288caeca8642d1e84afbd3f7d6820020 # v4\n- Accepts: node-version, node-version-file, architecture, check-latest inputs\n- No custom Node.js installation logic—delegates to the official GitHub action\n\n---\n\n2. Node.js-Specific Configurations Applied\n\nA. Node Version Management\n- Reads version from .nvmrc (default) or custom version file\n- Supports version specs: 12.x, 10.15.1, >=10.15.0, etc.\n- Can be overridden via node-version input\n\nB. npm Version Management (Lines 119-132)\n- Installs specific npm version if provided via npm-version input\n- Falls back to version in package.json's .engines.npm field\n- Converts open-majors (e.g., >=X.X.X) to latest (see COREFRONT-728 issue comment)\n- Defaults to npm version shipped with Node.js if none specified\n- Command: npm install -g npm@<version>\n\nC. Architecture Support\n- Includes runner.arch in cache keys (line 95) to prevent ARM64/AMD64 conflicts\n- Native binaries (esbuild, swc, etc.) in node_modules are architecture-specific\n\n---\n\n3. Doctolib-Specific Infrastructure Setup\n\nA. CodeArtifact Authentication (Lines 99-108)\nPurpose: Access private Doctolib npm packages\n\nSteps:\n1. CodeArtifact Login (Line 99-100)\n   - Calls doctolib/actions/codeartifact-login action\n   - Uses AWS IAM role for authentication\n   - Generates temporary CodeArtifact token (expires in 3600 seconds by default)\n   - Sets environment variable: CODEARTIFACT_AUTH_TOKEN\n\n2. Setup .npmrc (Lines 102-108)\n   - Configures npm registry for @doctolib scoped packages\n   - Registry URL: https://doctolib-580698825394.d.codeartifact.eu-west-1.amazonaws.com/npm/meta/\n   - Injects CodeArtifact auth token into .npmrc\n\nKey Details:\n- AWS Account ID: 580698825394\n- Region: eu-west-1\n- Scope: @doctolib packages only\n- Auth method: Token-based (generated from AWS credentials)\n\nB. S3-Based Caching (Lines 134-202)\nUses: Custom doctolib/actions/cache/* actions, NOT GitHub's native caching\n\nCache Strategy:\n1. node_modules cache (Lines 140-147, 197-202)\n   - Key: node-modules-${{ runner.arch }}-${{ node-version }}-${{ lockfile-hash }}\n   - Paths: Auto-detected or manually specified\n   - Saves build time by avoiding re-installation\n\n2. npm cache (Lines 149-158, 189-194)\n   - Key: setup-node-npm-${{ runner.arch }}-${{ node-version }}-${{ lockfile-hash }}\n   - Restore keys support partial matches for flexibility\n   - Fallback chain: primary key → partial match → fresh cache\n\nCache Behavior:\n- Restored from custom S3 backend via doctolib/actions/cache/restore and doctolib/actions/cache/save\n- Architecture-aware to prevent cross-platform incompatibilities\n- Conditional logic to skip saving if cache already hit (optimization)\n\nC. Lock File Validation (Lines 173-186)\nOptional lock file drift detection:\n- Runs npm i with --no-audit, --no-fund, --ignore-scripts flags\n- Compares git diff to detect if lock file changed\n- Fails CI if lock file is stale (via enable-lock-check input)\n- Helps prevent silent dependency mismatches\n\n---\n\n4. What Benefits pnpm Workflows?\n\nCould Be Reused:\n1. CodeArtifact Authentication\n   - pnpm can use .npmrc configuration (same as npm)\n   - The CodeArtifact token setup is package-manager agnostic\n   - pnpm respects .npmrc registry settings for scoped packages\n\n2. S3-Based Caching Infrastructure\n   - Doctolib's cache actions likely support caching any path\n   - Could cache pnpm store directory instead of node_modules\n   - Current setup-pnpm uses GitHub's actions/cache instead\n\n3. Lock File Validation Logic\n   - pnpm equivalent: pnpm-lock.yaml drift detection\n   - Same principle applies: run install with strict flags, check git diff\n   - Could be adapted for pnpm\n\n4. Architecture-Aware Cache Keys\n   - Already implemented in setup-node\n   - setup-pnpm also uses runner.arch (line 52)\n\nNOT Reusable:\n1. npm-Specific Version Management (lines 119-132)\n   - pnpm version is specified separately (not tied to Node.js version)\n   - Different .engines handling\n\n2. npm Postinstall Command (line 171)\n   - Only relevant for npm projects\n\n---\n\n5. Environment Variables & Configuration for pnpm\n\n| Variable/Config | setup-node | pnpm Needs? | Notes |\n|---|---|---|---|\n| CODEARTIFACT_AUTH_TOKEN | Sets (line 55) | ✅ YES | pnpm reads .npmrc for auth |\n| .npmrc registry config | Sets (lines 105-108) | ✅ YES | Scoped package registry |\n| Node.js version | Installs (line 110) | ✅ YES | pnpm requires Node.js runtime |\n| npm version | Installs (line 124-130) | ❌ NO | pnpm doesn't need npm |\n| node_modules cache | Manages | ⚠️ OPTIONAL | pnpm uses store cache, not node_modules |\n| Architecture in cache key | Included (line 95) | ✅ YES | Native binaries architecture-sensitive |\n\n---\n\n6. What setup-node Does Beyond npm\n\n1. Node.js Installation ✅ Needed by all Node-based workflows\n2. CodeArtifact Registry Setup ✅ Needed by Doctolib projects (regardless of package manager)\n3. S3 Caching Infrastructure ✅ Beneficial for any Node-based build (not npm-specific)\n4. Lock File Validation ✅ Applicable to pnpm (different file, same concept)\n5. Architecture-Aware Cache Keys ✅ Critical for both npm and pnpm\n\n---\n\n7. Viability of Extending setup-pnpm to Include Node.js\n\nRecommendation: YES, with caveats\n\nBenefits:\n- Single action for Node.js + pnpm setup with Doctolib infrastructure\n- Consistent CodeArtifact authentication across package managers\n- Unified caching strategy (though pnpm uses different cache paths)\n- Centralized lock file validation\n\nImplementation Considerations:\n- Add pnpm-version input to setup-node OR\n- Create setup-node-and-pnpm composite action that:\n  1. Calls actions/setup-node (skip npm version management)\n  2. Installs pnpm via pnpm/action-setup\n  3. Shares CodeArtifact login + .npmrc setup\n  4. Uses appropriate cache paths for pnpm store\n\nWhat to Skip for pnpm:\n- postinstall-command (npm-specific)\n- install-command (could adapt, but pnpm defaults to pnpm install)\n- npm-version management\n\nShared Across Both:\n- codeartifact-login\n- .npmrc scoped package registry configuration\n- S3 caching (with different paths)\n- Working directory support\n- Lock file validation (adapt to pnpm-lock.yaml)\n\n---\n\nKey Files Referenced\n\n- Primary: /Users/USER/workspace/doctolib/actions/setup-node/action.yml (203 lines)\n- Comparison: /Users/USER/workspace/doctolib/actions/setup-pnpm/action.yml (62 lines)\n- Dependencies: /Users/USER/workspace/doctolib/actions/codeartifact-login/action.yml` (72 lines)",
