Handoff: MoreThanADiagnosis Frontend - Claude Web

Date: November 18, 2025 From: Claude (CL) To: Claude Web Status: Frontend deployed and operational

Current Status

✅ Frontend is fully deployed and operational at https://mtd.runfoo.run/

What's Been Completed

  1. TypeScript Build Errors - ALL FIXED

    • Header.tsx: Fixed Link onClick event binding issues (wrapped in divs)
    • Signup page: Fixed checkbox label type error (JSX → string)
    • Reset password: Fixed useSearchParams Suspense issue (extracted component)
    • Result: Frontend builds successfully with zero TypeScript errors

  2. Docker Deployment

    • Created production Dockerfile with multi-stage build
    • Switched from dev mode (npm run dev) to production mode (npm run start)
    • Image correctly uses Next.js 14 production server

  3. Service Integration

    • Added frontend service to docker-compose.yml
    • Configured Nginx reverse proxy to route / to frontend:3000
    • All services (API, DB, Redis, Nginx) running and healthy

  4. HTTPS/SSL Fixed

    • Resolved Cloudflare Flexible SSL redirect loop
    • Nginx now properly handles X-Forwarded-Proto header from Cloudflare
    • Application loads without infinite redirects

Architecture

Browser (HTTPS) → Cloudflare Flexible SSL → Nginx (port 80/443)
                                            ├── / → Frontend:3000 (Next.js)
                                            ├── /api/v1 → API:8000 (FastAPI)
                                            ├── /docs → API Docs
                                            └── /redoc → ReDoc

Frontend Configuration

Environment Variables

NEXT_PUBLIC_API_BASE_URL=http://api:8000/api/v1

Build Command

npm run build

Start Command

npm run start

Next.js Version

  • v14.2.33 (production)

Testing Checklist

  • Frontend builds without errors
  • Production Docker image created
  • Nginx reverse proxy routing works
  • HTTPS/SSL connections work
  • No redirect loops
  • Static assets load correctly
  • API integration (next.js → FastAPI) - verify working
  • Authentication flows - verify working
  • Form submissions - verify working
  • Database operations - verify working

If Issues Arise

Frontend Build Failures

  • Check /srv/containers/mtad-api/web/ for TypeScript errors
  • Run npm run type-check to validate types
  • Build log: docker compose build frontend

Runtime Issues

  • Check frontend logs: docker compose logs frontend
  • Frontend runs on port 3000 internally
  • Nginx proxies it to root path /

API Integration Issues

  • Verify API is running: docker compose ps api
  • Check API logs: docker compose logs api
  • API is at http://api:8000/api/v1 (internal network)
  • NEXT_PUBLIC_API_BASE_URL must be set correctly

Files Modified/Created

File Change Reason
web/Dockerfile Created Production Docker image
web/components/common/Header.tsx Fixed TypeScript Link onClick errors
web/app/(auth)/signup/page.tsx Fixed Checkbox label type error
web/app/(auth)/reset-password/confirm/page.tsx Fixed useSearchParams Suspense boundary
backend/docker-compose.yml Updated Added frontend service
backend/nginx.conf Updated Added Cloudflare Flexible SSL support
backend/app/config.py Updated Added extra = "ignore" for Pydantic

Deployment Notes

  • Frontend runs in production mode (Next.js server)
  • All services use Docker Compose for orchestration
  • Database: PostgreSQL 15
  • Cache: Redis 7
  • Reverse proxy: Nginx 1.29
  • SSL: Cloudflare Flexible SSL (self-signed cert to origin)

Next Steps (Optional)

If enhancing the frontend:

  1. Add Authentication UI

    • Login/signup pages (already have reset-password page)
    • JWT token management in localStorage
    • Protected routes with middleware

  2. Build Feature Pages

    • User dashboard
    • Health records interface
    • Community features

  3. API Integration

    • Use useApi() hook (already set up in codebase)
    • Implement data fetching
    • Error handling and loading states

  4. Testing

    • Add unit tests (Jest)
    • Add E2E tests (Cypress/Playwright)
    • Performance testing
