## 🔧 CONFIGURATION

### Environment Variables (Frontend)

Create `frontend/.env.local`:
```
VITE_API_URL=http://localhost:3005
VITE_OAUTH_REDIRECT_URI=http://localhost:5173/#/callback
```

### Environment Variables (Backend)

Create `Mode3Test/.env`:
```
OAUTH_CLIENT_ID=your-microsoft-client-id
OAUTH_CLIENT_SECRET=your-microsoft-client-secret
OAUTH_REDIRECT_URI=http://localhost:5173/#/callback
CORS_ORIGIN=http://localhost:5173
NODE_ENV=production
PORT=3005
```

### OAuth2 Setup

1. Register app at [Azure Portal](https://portal.azure.com)
2. Get Client ID and Client Secret
3. Set redirect URI: `http://localhost:5173/#/callback`
4. Add credentials to `.env` files

## ✅ VERIFICATION CHECKLIST

After starting the application, verify:

- [ ] Frontend loads at http://localhost:5173
- [ ] Sign in button visible
- [ ] Can sign in with Microsoft OAuth
- [ ] User profile shows in header
- [ ] Jobs load automatically
- [ ] Search filters jobs
- [ ] Can sign out
- [ ] Service Worker active (DevTools → Application)
- [ ] IndexedDB populated (DevTools → Storage)
- [ ] No console errors (DevTools → Console)
- [ ] No TypeScript errors (build verified)

All should be ✅ for successful deployment.

## 🐛 TROUBLESHOOTING

### Port 3005 or 5173 Already In Use

```bash
# Find process using port
lsof -i :3005
lsof -i :5173

# Kill process
kill -9 <PID>

# Or use alternative ports
PORT=3006 bun run dev    # Backend
npm run dev -- --port 5174  # Frontend
```

### OAuth Not Working

1. Check `.env` has correct credentials
2. Verify redirect URI in OAuth app settings
3. Redirect URI must be: `http://localhost:5173/#/callback`
4. Restart backend after changing `.env`

### Service Worker Not Registering

1. Check browser is using HTTPS or localhost
2. Clear browser cache (Ctrl+Shift+Delete)
3. Check DevTools → Application → Service Workers
4. May need to restart frontend dev server

### Docker Build Fails

```bash
# Clear Docker cache
docker system prune -a

# Rebuild
docker-compose build --no-cache

# Start
docker-compose up -d
```
