# 🎉 Web UI Implementation Complete!

## What Just Happened?

I've created a **complete, production-ready web application scaffolding** for RDFMap that works exactly like Neo4j - a containerized backend + frontend that you can start with one command.

## 🎯 How to Start RIGHT NOW

### Option 1: Super Simple (Recommended)

```bash
cd /Users/rxcthefirst/Dev/PythonProjects/SemanticModelDataMapper
./start-web-ui.sh
```

**That's it!** The script will:
1. ✅ Check for Docker/Docker Compose
2. ✅ Create `.env` file with secure secrets
3. ✅ Check port availability
4. ✅ Build all containers
5. ✅ Start all services
6. ✅ Wait for API to be ready
7. ✅ Show you all access URLs

Then open: **http://localhost:8080**

### Option 2: Manual

```bash
# Copy environment template
cp .env.example .env

# Start everything
docker-compose up -d

# Watch logs
docker-compose logs -f api

# Open browser
open http://localhost:8080
```

---

## 🌐 What You Can Access

Once started, you'll have:

| Service | URL | Description |
|---------|-----|-------------|
| **Web UI** | http://localhost:8080 | React frontend |
| **API Docs** | http://localhost:8000/api/docs | Swagger UI (interactive!) |
| **API Health** | http://localhost:8000/api/health | Health check |
| **Dev Server** | http://localhost:5173 | Vite (hot reload) |

---

## 🧪 Test It Out

```bash
# Check health
curl http://localhost:8000/api/health

# Create a project
curl -X POST http://localhost:8000/api/projects \
  -H "Content-Type: application/json" \
  -d '{
    "name": "My First Project",
    "description": "Testing the new Web UI"
  }'

# List projects
curl http://localhost:8000/api/projects

# Try the interactive API docs
open http://localhost:8000/api/docs

## 🛠️ Development Workflow

### Make Changes (Hot Reload Enabled!)

**Backend:**
```bash
# Edit backend/app/routers/projects.py
# Save file
# Changes auto-reload! ✨
```

**Frontend:**
```bash
# Edit frontend/src/pages/ProjectList.tsx
# Save file
# Browser auto-refreshes! ✨
```

### View Logs
```bash
# All services
docker-compose logs -f

# Just API
docker-compose logs -f api

# Just UI
docker-compose logs -f ui
```

### Restart a Service
```bash
docker-compose restart api
docker-compose restart ui
```

### Rebuild After Dependency Changes
```bash
# Backend (added package to requirements.txt)
docker-compose build api
docker-compose up -d api

# Frontend (added package to package.json)
docker-compose build ui
docker-compose up -d ui
```

## 🎯 Recommended Next Actions

### This Week (If You Want to Start Immediately)

1. **Start the application:**
   ```bash
   ./start-web-ui.sh
   ```

2. **Explore the API:**
   - Open http://localhost:8000/api/docs
   - Try creating a project
   - Try uploading files

3. **Explore the UI:**
   - Open http://localhost:8080
   - See the project list
   - Check the browser console

4. **Read the architecture doc:**
   - Understand the design decisions
   - Review the implementation plan
   - Familiarize with tech stack

### Next Week (Backend Integration)

1. **Create `backend/app/services/rdfmap_service.py`:**
   ```python
   from rdfmap import MappingGenerator, GeneratorConfig
   from rdfmap.emitter.graph_builder import RDFGraphBuilder
   
   class RDFMapService:
       def generate_mappings(self, ontology_path, data_path):
           # Wrap your MappingGenerator
           pass
       
       def convert_to_rdf(self, mapping_config):
           # Wrap your RDFGraphBuilder
           pass
   ```

2. **Update `backend/app/routers/mappings.py`:**
   ```python
   @router.post("/{project_id}/generate")
   async def generate_mappings(project_id: str):
       service = RDFMapService()
       result = service.generate_mappings(...)
       return result
   ```

3. **Test with your mortgage example:**
   - Upload `examples/mortgage/data/loans.csv`
   - Upload `examples/mortgage/ontology/mortgage.ttl`
   - Call `/generate` endpoint
   - Verify it returns mappings

### Following Weeks (UI Enhancement)

4. **Add React Flow visual editor**
5. **Add file upload components**
6. **Add ontology graph visualization**
7. **Add RDF preview panel**

## 💡 Pro Tips

### 1. Use the Auto-Generated API Docs
The Swagger UI at http://localhost:8000/api/docs is **interactive**:
- Try endpoints directly in the browser
- See request/response schemas
- Download OpenAPI spec

### 2. Hot Reload is Your Friend
Both backend and frontend have hot reload enabled:
- Save file → see changes immediately
- No need to restart containers
- Faster development iteration

### 3. Use Docker Logs for Debugging
```bash
# Real-time logs
docker-compose logs -f api

# Search logs
docker-compose logs api | grep ERROR

# Last 100 lines
docker-compose logs --tail=100 api
```

### 4. Reset Everything When Stuck
```bash
# Nuclear option (deletes all data!)
docker-compose down -v
docker-compose build --no-cache
docker-compose up -d
```

### 5. Develop Locally Without Docker (Faster)
```bash
# Backend
cd backend
python -m venv venv
source venv/bin/activate
pip install -r requirements.txt
uvicorn app.main:app --reload

# Frontend (in another terminal)
cd frontend
npm install
npm run dev
```
