# 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
```bash
npm run build
```
### Start Command
```bash
npm run start
```
### Next.js Version
- v14.2.33 (production)
---
## Known Working Features
- ✅ Homepage with welcome message and navigation
- ✅ API documentation links (/docs, /redoc)
- ✅ Health endpoint access
- ✅ Tailwind CSS styling (responsive layout)
- ✅ All TypeScript components compile without errors
- ✅ Production-optimized build
---
## Testing Checklist
- [x] Frontend builds without errors
- [x] Production Docker image created
- [x] Nginx reverse proxy routing works
- [x] HTTPS/SSL connections work
- [x] No redirect loops
- [x] 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

## 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
