Design a detailed implementation plan for Phase 1 of the pnpm migration for the docto-crypt repository.

Context from Exploration

Repository: docto-crypt - A Maven/JVM project (Java/Kotlin) that uses npm as a wrapper for publishing - Current version: 0.9.6 - Node version: 22.16.0 (from .nvmrc) - No npm dependencies (it's a JVM library published to npm) - Maven wrapper used for actual builds

Current package.json scripts:

{
  "build": "./mvnw clean package -Drevision=$npm_package_version",
  "maven:install": "./mvnw install -Drevision=$npm_package_version -Dmaven.build.cache.enabled=false",
  "test": "./mvnw test",
  "clean": "./mvnw clean",
  "prepublishOnly": "npm run build"
}

Current GitHub Workflows: 1. java-test.yml - Runs on PR/merge/push to main - Uses Java 17 with Zulu - Runs ./mvnw spotless:check (code formatting) - Runs ./mvnw clean verify --fail-at-end - Uses doctolib/actions/setup-java with Maven caching

2. publish.yml - Runs on push to main + manual trigger - Uses Java 21 with Zulu - Runs ./mvnw clean package and ./mvnw test - Uses doctolib/actions/setup-node for Node.js - Uses doctolib/actions/publish-npm-codeartifact to publish with npm publish

Doctolib Actions Repository: - NO existing pnpm actions found - setup-node action exists but only supports npm - Pattern for creating new actions: {verb}-{noun} format - Actions use composite action pattern with caching support

Requirements

1. Dual npm/pnpm Support: Both package managers should be able to run the same scripts
2. GitHub Actions: - Check if existing pnpm actions are available (we found NONE) - Suggest new actions if needed
3. Manual Trigger: pnpm workflow should be manually triggered (workflow_dispatch)
4. Phase 1 Goals (from TEP): - Convert to pnpm workspaces (if applicable - not applicable here as it's a single package) - Update CI/CD pipelines - Test build, test, and deployment workflows - Document issues and solutions - Measure performance improvements vs npm baseline - Success criteria: All tests passing, CI/CD functioning, install time reduced >50%, zero production issues

Design Requirements

Please design: 1. package.json modifications to support both npm and pnpm 2. pnpm configuration files needed (.npmrc updates, pnpm-workspace.yaml if needed) 3. New GitHub workflow for pnpm (manually triggered) that parallels the existing npm workflows 4. New GitHub Actions to be created in doctolib/actions for pnpm support 5. Documentation needs (runbook, migration notes) 6. Testing approach to validate pnpm works correctly 7. Performance metrics to capture for comparison

Consider: - This is a Maven project, so pnpm won't manage dependencies (Maven does) - pnpm is primarily for the publishing workflow - Need to maintain backward compatibility with npm - Should follow Doctolib's patterns for GitHub Actions - The workflow should run in parallel with npm initially for validation

Now I have enough information to design a comprehensive implementation plan. Let me create the detailed plan document.

Phase 1 pnpm Migration - Implementation Plan for docto-crypt

Executive Summary

This plan outlines the implementation of Phase 1 pnpm migration for the docto-crypt repository. Since docto-crypt is a Maven/JVM project that uses npm only as a wrapper for publishing (no Node.js dependencies), the migration focus is on:

1. Publishing workflow compatibility with pnpm
2. Parallel validation of pnpm vs npm workflows
3. Performance metrics collection
4. Creating reusable GitHub Actions for future Doctolib projects

Current State Analysis

Repository Characteristics

• Type: Maven/JVM project (Java/Kotlin)
• Package Manager Role: npm used only for versioning and publishing to CodeArtifact
• No Node Dependencies: All dependencies managed by Maven
• Build Tool: Maven wrapper (mvnw)
• Node Version: 22.16.0
• Current Version: 0.9.6

Current Workflows

1. java-test.yml: Runs tests, code formatting checks (Java 17)
2. publish.yml: Builds and publishes to npm CodeArtifact (Java 21)

Key Insight

Since there are no Node.js dependencies to install, the primary pnpm benefit will be: - Faster npm publish command execution - Validation of pnpm compatibility with Maven-based npm packages - Establishing patterns for other Doctolib projects

Design Decisions

1. Dual Package Manager Support Strategy

Decision: Maintain full backward compatibility with npm while adding pnpm support.

Rationale: - Zero risk to existing workflows - Allows gradual validation and rollback if issues arise - Enables performance comparison

Implementation: - Keep existing npm workflows unchanged - Add new pnpm-specific workflow (manually triggered) - Use identical scripts in package.json for both package managers

2. pnpm Configuration

Files to Create:

.npmrc (new file)

# pnpm configuration
# Enable strict peer dependencies (pnpm default, explicit for clarity)
strict-peer-dependencies=true

# Use same registry as npm for consistency
# Note: CodeArtifact registry will be configured via environment variables in CI

# Lockfile settings
lockfile=true

# Store configuration - use default pnpm store for CI caching
# No need to specify store-dir, use pnpm defaults

# Hoisting configuration - not applicable for this project (no node_modules)
# but explicit for documentation
hoist=true

Rationale: - Minimal configuration since there are no dependencies - Explicit settings for future reference - Compatible with CodeArtifact authentication

pnpm-workspace.yaml

Decision: NOT NEEDED for docto-crypt

Rationale: - Single package repository - No workspaces needed - Adding this file would add unnecessary complexity

3. package.json Modifications

Decision: No modifications required to package.json

Rationale: - Current scripts use npm_package_version environment variable - pnpm sets the same environment variables as npm - Scripts are already package-manager agnostic: ```json "build": "./mvnw clean package -Drevision=$npm_package_version"

- Maven wrapper is directly executable, no package manager involvement

**Validation Needed**:
- Verify pnpm sets `npm_package_version` environment variable correctly
- Test `prepublishOnly` hook fires with pnpm publish

### 4. GitHub Actions Design

Since no pnpm actions exist in doctolib/actions, we need to create:

#### New Action: setup-pnpm

**Location**: `doctolib/actions/setup-pnpm/action.yml`

**Design**:
```yaml
name: 'Setup pnpm'
description: 'Setup pnpm with caching support'
inputs:
pnpm-version:
  description: 'pnpm version to install'
  required: false
  default: '9'  # Latest stable v9
node-version:
  description: 'Node.js version (if not already installed)'
  required: false
  default: ''
run-install:
  description: 'Whether to run pnpm install'
  required: false
  default: 'false'  # Default false for docto-crypt (no deps)
cache:
  description: 'Enable pnpm store caching'
  required: false
  default: 'true'

runs:
using: 'composite'
steps:
  - name: Setup Node.js
    if: inputs.node-version != ''
    uses: actions/setup-node@v4
    with:
      node-version: ${{ inputs.node-version }}

  - name: Install pnpm
    uses: pnpm/action-setup@v4
    with:
      version: ${{ inputs.pnpm-version }}
      run_install: false  # We control installation separately

  - name: Get pnpm store directory
    if: inputs.cache == 'true'
    shell: bash
    run: |
      echo "STORE_PATH=$(pnpm store path --silent)" >> $GITHUB_ENV

  - name: Setup pnpm cache
    if: inputs.cache == 'true'
    uses: actions/cache@v4
    with:
      path: ${{ env.STORE_PATH }}
      key: ${{ runner.os }}-pnpm-store-${{ hashFiles('**/pnpm-lock.yaml') }}
      restore-keys: |
        ${{ runner.os }}-pnpm-store-

  - name: Install dependencies
    if: inputs.run-install == 'true'
    shell: bash
    run: pnpm install --frozen-lockfile

Features: - Follows Doctolib actions pattern (composite action) - Configurable pnpm version - Optional Node.js setup (can use existing setup-node) - Smart caching of pnpm store - Optional install step (default: false for docto-crypt)

New Action: publish-pnpm-codeartifact

Location: doctolib/actions/publish-pnpm-codeartifact/action.yml

Design:

name: 'Publish to CodeArtifact with pnpm'
description: 'Authenticate and publish npm packages to AWS CodeArtifact using pnpm'
inputs:
  command:
    description: 'pnpm publish command to run'
    required: false
    default: 'pnpm publish --no-git-checks'
  pre-release:
    description: 'Whether this is a pre-release'
    required: false
    default: 'false'
  aws-region:
    description: 'AWS region for CodeArtifact'
    required: false
    default: 'eu-west-3'
  codeartifact-domain:
    description: 'CodeArtifact domain'
    required: false
    default: 'doctolib'
  codeartifact-repository:
    description: 'CodeArtifact repository'
    required: false
    default: 'npm-packages'

runs:
  using: 'composite'
  steps:
    - name: Configure AWS credentials
      uses: aws-actions/configure-aws-credentials@v4
      with:
        role-to-assume: ${{ env.AWS_CODEARTIFACT_ROLE }}
        aws-region: ${{ inputs.aws-region }}

    - name: Get CodeArtifact token
      shell: bash
      run: |
        CODEARTIFACT_TOKEN=$(aws codeartifact get-authorization-token \
          --domain ${{ inputs.codeartifact-domain }} \
          --domain-owner ${{ env.AWS_ACCOUNT_ID }} \
          --query authorizationToken \
          --output text)
        echo "::add-mask::$CODEARTIFACT_TOKEN"
        echo "CODEARTIFACT_TOKEN=$CODEARTIFACT_TOKEN" >> $GITHUB_ENV

    - name: Configure pnpm registry
      shell: bash
      run: |
        REGISTRY_URL=$(aws codeartifact get-repository-endpoint \
          --domain ${{ inputs.codeartifact-domain }} \
          --domain-owner ${{ env.AWS_ACCOUNT_ID }} \
          --repository ${{ inputs.codeartifact-repository }} \
          --format npm \
          --query repositoryEndpoint \
          --output text)

        pnpm config set registry "$REGISTRY_URL"
        pnpm config set "//$REGISTRY_URL:_authToken" "$CODEARTIFACT_TOKEN"

    - name: Publish package
      shell: bash
      run: ${{ inputs.command }}

Features: - Mirror of npm version but using pnpm - CodeArtifact authentication - Configurable command - Supports pre-release flag - Uses environment variables for AWS credentials

5. New GitHub Workflow: publish-pnpm.yml

Location: .github/workflows/publish-pnpm.yml

Design:

name: Publish Package (pnpm)

on:
  workflow_dispatch:  # Manual trigger only for Phase 1
    inputs:
      dry-run:
        description: 'Run in dry-run mode (no actual publish)'
        required: false
