Adds migration strategy docs outlining PR plan, repo options, next steps, and RSC recommendations. Seeds conversion candidate lists plus scripts and README templates for organizing demo conversions. Provides shadcn starter conversion plan materials so future React on Rails demos have a clear roadmap.

Add comprehensive research on converting Inertia.js apps to React on Rails:

1. VITE_RAILS_REACT_SSR_EXAMPLES.md
   - Top 10 React-only examples (Vue excluded)
   - Evil Martians inertia-rails/react-starter-kit highlighted
   - Detailed analysis of each project's conversion value
   - Updated to reflect Nov 2025 maintenance status

2. INERTIA_TO_REACT_ON_RAILS_CONVERSION_PLAN.md
   - Complete conversion plan from Inertia to React on Rails
   - Dependency migration (Inertia → React on Rails, Vite → Shakapacker+Rspack)
   - File-by-file conversion mappings
   - Component migration patterns
   - SSR configuration differences
   - Deployment updates for reactrails.com

Key findings:
- inertia-rails/react-starter-kit is most modern (Nov 2025)
- ElMassimo/inertia-rails-ssr-template is outdated (July 2022)
- Shakapacker 9.x supports Rspack for faster builds
- Full conversion plan ready for new workspace

PR Review: SSR Conversion Documentation and Demo Scaffolds

Summary

This PR adds comprehensive planning documentation and scaffolding for SSR conversion demos. The materials provide detailed strategies for converting Inertia.js applications to React on Rails with Rspack. Overall, this is excellent strategic documentation that will guide future implementation work.

✅ Strengths

1. Comprehensive Planning ⭐⭐⭐⭐⭐

  • Extremely detailed conversion plans with step-by-step instructions
  • Multiple strategy documents (PR-based migration vs. new repo)
  • Well-organized phased approach with clear milestones
  • Realistic time estimates and priority classifications

2. Documentation Quality ⭐⭐⭐⭐⭐

  • INERTIA_TO_REACT_ON_RAILS_CONVERSION_PLAN.md: 799 lines of detailed migration guidance
  • MIGRATION_PR_STRATEGY.md: Thoughtful incremental migration approach
  • NEW_REPO_STRATEGY.md: Clear repository setup alternatives
  • Excellent use of before/after code examples
  • Helpful tables comparing approaches

3. Practical Scripts ⭐⭐⭐⭐

  • create_new_repo.sh: Automates new repo creation
  • setup_demo_directories.sh & setup_2024_demos.sh: Generate consistent demo scaffolds
  • Good use of color output for user feedback
  • Proper error handling (e.g., 2>/dev/null || true)

4. Strategic Thinking ⭐⭐⭐⭐⭐

  • NEW_REPO_STRATEGY.md correctly identifies why a new repo is better than a fork
  • RECOMMENDATION_RSC.md provides forward-looking guidance on React Server Components
  • Multiple conversion candidate lists show thorough research
  • Clear success criteria and verification checklists

🔍 Issues & Recommendations

Critical: Hardcoded Paths in Scripts 🚨

Issue: create_new_repo.sh:9-10 contains hardcoded paths specific to your machine:

SOURCE_DIR="/Users/justin/conductor/react-starter-kit"
TARGET_DIR="/Users/justin/conductor/$REPO_NAME"

Impact: Script will fail for any other user

Recommendation: Make paths configurable with environment variables or prompts

Medium: Script Safety Improvements

Issue 1: create_new_repo.sh does not validate SOURCE_DIR exists before copying files

Recommendation: Add validation checks before operations

Issue 2: create_new_repo.sh:28 has dangerous rm -rf .git without confirmation

Recommendation: Add user confirmation before destructive operations

Minor: Documentation Consistency

  • demos/shadcn-ui-ssr-modern/CONVERSION_PLAN.md:40 mentions shakapacker ~> 8.0
  • Should be ~> 9.0 per CLAUDE.md guidelines
  • Shell scripts missing executable permissions (need chmod +x *.sh)
  • Demo READMEs contain unfilled placeholders like [GitHub URL] and [Original technology stack]

📊 Code Quality Assessment

Category Rating Notes
Documentation Quality ⭐⭐⭐⭐⭐ Exceptional detail and clarity
Code Examples ⭐⭐⭐⭐⭐ Accurate before/after comparisons
Script Safety ⭐⭐⭐ Works but needs validation
Portability ⭐⭐ Hardcoded paths limit reuse
Completeness ⭐⭐⭐⭐⭐ Covers all aspects thoroughly

🔒 Security Considerations

No security issues identified

  • Scripts do not execute remote code
  • No credential handling
  • No unsafe eval or injection points
  • Appropriate use of heredocs
  • .gitignore additions follow good security practices

🎯 Performance Considerations

Excellent performance focus:

  • Detailed benchmarks in conversion plans (build time, TTI, bundle size)
  • Rspack chosen specifically for faster builds than Webpack
  • SSR implementation guidance includes performance notes

Suggestion: Add actual benchmark baseline data once conversions begin

🧪 Testing

⚠️ No automated tests for scripts

  • Shell scripts should have basic validation tests
  • Consider adding shellcheck to CI
  • Test demo scaffold generation in CI pipeline

📝 Alignment with CLAUDE.md

Follows upgrade guidelines:

  • Correctly emphasizes version-only updates
  • Warns against running install commands that overwrite configs
  • Documents proper upgrade workflow

⚠️ One minor inconsistency:

  • Some docs mention Shakapacker 8.x instead of 9.x
  • Update to match latest version recommended

🎓 Best Practices Adherence

Excellent:

✅ Attribution to original authors (Evil Martians credit)
✅ Clear migration paths for users
✅ Comprehensive before/after examples
✅ Phased implementation approach
✅ Success criteria and verification checklists

Could Improve:

⚠️ Script portability (hardcoded paths)
⚠️ Error handling in shell scripts
⚠️ Placeholder cleanup in templates

💡 Suggestions for Future Work

High Priority:

  1. Fix hardcoded paths in create_new_repo.sh
  2. Add validation to all shell scripts
  3. Update version references to Shakapacker 9.x throughout docs

Medium Priority:

  1. Add shellcheck to CI pipeline for script validation
  2. Create actual demo implementations (current PR is scaffolding only)
  3. Fill in or remove placeholder content in demo READMEs

Low Priority:

  1. Add performance benchmarking tooling
  2. Create conversion progress tracking (GitHub Projects?)
  3. Add community contribution guidelines

🎉 Final Verdict

Recommendation: ✅ APPROVE with minor fixes

This PR provides excellent strategic foundation for the SSR conversion work. The documentation is comprehensive, well-organized, and demonstrates deep understanding of both Inertia.js and React on Rails architectures.

Before Merging:

  1. Fix hardcoded paths in create_new_repo.sh
  2. Add error handling to scripts
  3. Update Shakapacker version references to 9.x
  4. Make scripts executable: chmod +x *.sh

Post-Merge:

  • Begin actual implementation using these guides
  • Update docs with real-world learnings from conversions
  • Add automated testing for scripts

Great work on the planning! This will be very helpful for the conversion projects. 🚀
