Phase 7-8: Final Monorepo Polish and Documentation

[justin808]

Summary

Complete the final phases (7-8) of the monorepo migration with CI/CD polish and comprehensive documentation updates.

Status: Most CI work done, documentation updates needed

Background

• Phase 5 ✅ Complete (PR Phase 5: Add Pro Node Renderer Package to workspace #2069 - Node renderer package extraction)
• Phase 6 🚧 Next (Issue Phase 6: Restructure Ruby Gems to Final Monorepo Layout #2103 - Ruby gem restructuring)
• Phase 7-8 📋 Final polish (this issue)

Phase 7: CI/CD Polish

✅ Already Completed

• CircleCI to GitHub Actions migration
• Unified workflows for both packages
• Matrix builds for Ruby/Node versions

Remaining Tasks

7.1: Add Automated License Compliance Check

• Create .github/workflows/license-check.yml
• Verify Pro files have license headers (Ruby + JS/TS)
• Verify no Pro code in MIT directories
• Verify LICENSE.md lists all Pro directories
• Run on every PR

Example workflow:

name: License Compliance
on: [push, pull_request]
jobs:
  license-check:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Check Pro license headers
        run: |
          # Check Ruby files
          find lib/react_on_rails_pro packages/react-on-rails-pro* -name "*.rb" | \
          while read file; do
            if ! head -20 "$file" | grep -q "Pro License\|UNLICENSED"; then
              echo "❌ Missing license header: $file"
              exit 1
            fi
          done
      - name: Verify no Pro code in MIT dirs
        run: |
          if find lib/react_on_rails packages/react-on-rails -type f \
            -exec grep -l "ReactOnRailsPro" {} \; | grep .; then
            exit 1
          fi

7.2: License Verification Scripts

• Create bin/verify-licenses script
• Add to pre-commit hook
• Add to release checklist

7.3: CI Status Badges

• Update README.md status badges if needed
• Ensure badges reflect new workflow names

Phase 8: Documentation & Polish

8.1: Update Main README.md

• Add clear licensing section showing package breakdown
• Update installation instructions for monorepo structure
• Add section on monorepo development workflow
• Update architecture diagram (if exists)
• Clarify which packages are MIT vs Pro

Example:

## Packages

This monorepo contains:

### MIT Licensed
- `react-on-rails` (Ruby gem) - Rails integration
- `react-on-rails` (NPM package) - Client-side React integration

### Pro Licensed
- `react-on-rails-pro` (Ruby gem) - Pro Rails features
- `react-on-rails-pro` (NPM package) - Pro client features
- `react-on-rails-pro-node-renderer` (NPM package) - Node.js server rendering

8.2: Create Package READMEs

• packages/react-on-rails/README.md (MIT package)
  • What it does
  • How to install
  • License: MIT
  • Link to main docs
• packages/react-on-rails-pro/README.md (Pro package)
  • What it does
  • How to get Pro license
  • License: UNLICENSED
  • Link to Pro docs
• packages/react-on-rails-pro-node-renderer/README.md
  • What it does
  • Dependencies
  • License: UNLICENSED

8.3: Create Migration Guide

• Create docs/monorepo-migration-guide.md for existing contributors
• Document what changed and what didn't
• Provide step-by-step local setup instructions
• Add troubleshooting section
• Common migration issues and solutions

Topics to cover:

• Directory structure changes
• How to update local clones
• New build commands
• Workspace commands
• YALC publishing workflow

8.4: Update Examples

• Verify all example apps work with new structure
• Update example app documentation
• Ensure examples respect license boundaries
• Update generator templates if needed

8.5: Update CHANGELOG

• Create comprehensive changelog entry for monorepo migration
• Document structural changes (not breaking changes for users)
• List new package structure
• Add migration guide link
• Note for contributors about path changes

Example:

## [Unreleased]

### Changed (Internal - Contributors Only)
- Restructured repository to monorepo layout
- Ruby gems now at `lib/react_on_rails/` and `lib/react_on_rails_pro/`
- NPM packages now in `packages/` workspace
- See docs/monorepo-migration-guide.md for contributor migration guide

**Note:** This is an internal restructuring. No API changes for users.

8.6: Update Contributing Guide

• Update CONTRIBUTING.md for monorepo workflow
• Document workspace commands
• Update local development setup
• Document YALC workflow
• Add monorepo-specific troubleshooting

8.7: Update CLAUDE.md

• Update file paths in examples
• Add monorepo-specific development notes
• Update test commands for workspace
• Add workspace management guidance

Testing Checklist

Before marking complete:

• All CI workflows pass
• License compliance check works
• Both gems build from root
• All 3 NPM packages build
• YALC publish works (after Fix TypeScript Build Errors in Node-Renderer Package #2104 fixed)
• Example apps work
• Documentation is accurate and complete
• No broken links in docs

---

Success Criteria

Phase 7 (CI/CD)

• Automated license compliance check in CI
• License verification script available
• No manual license checking needed

Phase 8 (Documentation)

• Main README reflects monorepo structure
• All packages have READMEs
• Migration guide exists and is comprehensive
• CHANGELOG documents the migration
• All example apps documented and working
• Contributing guide updated

Related Issues

• Phase 6: Restructure Ruby Gems to Final Monorepo Layout #2103 - Phase 6: Restructure Ruby Gems (prerequisite)
• Fix TypeScript Build Errors in Node-Renderer Package #2104 - Fix TypeScript build errors (enables full YALC workflow)
• Consolidate and Reorganize Monorepo Documentation #2105 - Consolidate documentation (cleanup task)

Estimated Effort

Phase 7: 4-6 hours (CI workflows and scripts)
Phase 8: 8-12 hours (comprehensive documentation)
Total: 2-3 days

Priority

Medium - Important for long-term maintainability, but not blocking current work

Can be done in parallel with or after Phase 6 (#2103)
