  • Stores: client/src/stores/ (all pattern implementations)

4. Add Endpoints

  • Copy Auth controller pattern
  • Update DTOs
  • Implement service logic
  • Test with Postman

5. Add UI

  • Use existing dashboard components
  • Create forms with React Hook Form
  • Use shadcn/ui components
  • Connect to stores

  • Integration points specified
  • Ready for production features

Next Steps

  1. Implement core modules (Auth, Users, Mess, Months)

    • Use auth module as reference
    • Follow same patterns
    • Add tests for each

  2. Build feature pages

    • Use dashboard as reference
    • Create forms with React Hook Form
    • Connect to stores
    • Use shadcn/ui

  3. Integration testing

    • Test full data flows
    • Test pagination
    • Test error handling
    • Test cache invalidation

  4. Deployment

    • Docker setup
    • Environment configuration
    • Database migrations
    • CI/CD pipeline
