# Crypto Monitor ULTIMATE - Deployment Guide

## ✅ Latest Fixes (2025-11-13)

### Dashboard Fixes
- ✅ **Inlined Static Files**: CSS and JS are now embedded in HTML (no more 404 errors)
- ✅ **WebSocket URL**: Fixed to support both HTTP (ws://) and HTTPS (wss://)
- ✅ **Permissions Policy**: Removed problematic meta tags causing warnings
- ✅ **Chart.js**: Added defer attribute to prevent blocking
- ✅ **All Functions**: Properly defined before use (no more "undefined" errors)

### Server Fixes
- ✅ **Dynamic PORT**: Server now reads `$PORT` environment variable
- ✅ **Startup Validation**: Graceful degraded mode for network-restricted environments
- ✅ **Static Files Mounting**: Proper mounting at `/static/` path
- ✅ **Version**: Updated to 3.0.0

## 🚀 Deployment Options

### 1. Hugging Face Spaces (Recommended)

#### Option A: Docker (Easier)

1. Create a new Space on Hugging Face
2. Select **"Docker"** as SDK
3. Push this repository to the Space
4. HF will automatically use the Dockerfile

**Environment Variables in Space Settings:**
```env
PORT=7860
ENABLE_AUTO_DISCOVERY=false
ENABLE_SENTIMENT=true
```

#### Option B: Python

1. Create a new Space on Hugging Face
2. Select **"Gradio"** or **"Static"** as SDK
3. Create `app.py` in root:

```python
import os
os.system("python api_server_extended.py")
```

4. Configure in Space settings:
   - Python version: 3.11
   - Startup command: `python api_server_extended.py`

---

### 2. Local Development

```bash
# Install dependencies
pip install fastapi uvicorn[standard] pydantic aiohttp httpx requests websockets python-dotenv pyyaml

# Run server (default port 8000)
python api_server_extended.py

# OR specify custom port
PORT=7860 python api_server_extended.py

# Access dashboard
http://localhost:8000  # or your custom port
```

---

### 3. Docker Deployment

```bash
# Build image
docker build -t crypto-monitor .

# Run container
docker run -p 8000:8000 crypto-monitor

# OR with custom port
docker run -e PORT=7860 -p 7860:7860 crypto-monitor

# Using docker-compose
docker-compose up -d
```

---

## 🔧 Configuration

### Environment Variables

Create `.env` file (or set in Hugging Face Space settings):

```env
# Server Configuration
PORT=7860  # Default for HF Spaces
HOST=0.0.0.0

# Features
ENABLE_AUTO_DISCOVERY=false  # Set to false for HF Spaces
ENABLE_SENTIMENT=true

# API Keys (Optional - most providers work without keys)
COINMARKETCAP_API_KEY=your_key_here
CRYPTOCOMPARE_API_KEY=your_key_here
ETHERSCAN_KEY_1=your_key_here
NEWSAPI_KEY=your_key_here

# HuggingFace (Optional)
HUGGINGFACE_TOKEN=your_token_here
SENTIMENT_SOCIAL_MODEL=ElKulako/cryptobert
SENTIMENT_NEWS_MODEL=kk08/CryptoBERT
```

## 📋 Verification Checklist

After deployment, verify:

- [ ] Dashboard loads at root URL (`/`)
- [ ] No 404 errors in browser console
- [ ] No JavaScript errors (check browser console)
- [ ] Health endpoint responds: `/health`
- [ ] API endpoints work: `/api/providers`, `/api/pools`, `/api/status`
- [ ] WebSocket connects (check connection status in dashboard)
- [ ] Provider stats display correctly
- [ ] All tabs switchable without errors

---

## 🐛 Troubleshooting

### Dashboard shows 404 errors for CSS/JS
**Fixed in latest version!** Static files are now inline.

### WebSocket connection fails
- Check if HTTPS: WebSocket will use `wss://` automatically
- Verify firewall allows WebSocket connections
- Check browser console for error messages

### Server won't start
```bash
# Check port availability
lsof -i:8000  # or your custom port

# Kill process if needed
pkill -f api_server_extended

# Check logs
tail -f server.log
```

### "Address already in use" error
```bash
# Change port
PORT=7860 python api_server_extended.py
```

## 🎯 Performance Tips

### For Hugging Face Spaces

1. **Disable Auto-Discovery**: Set `ENABLE_AUTO_DISCOVERY=false`
2. **Limit Dependencies**: Comment out heavy packages in `requirements.txt` if not needed:
   - `torch` (~2GB)
   - `transformers` (~1.5GB)
   - `duckduckgo-search`

3. **Use Smaller Docker Image**: Dockerfile already uses `python:3.11-slim`

### For Production

1. **Enable Redis Caching**:
   ```bash
   docker-compose --profile observability up -d
   ```

2. **Add Rate Limiting**: Configure nginx/Cloudflare in front

3. **Monitor Resources**: Use Prometheus/Grafana (included in docker-compose)

## 📊 Resource Requirements

### Minimum
- **RAM**: 512MB
- **CPU**: 1 core
- **Disk**: 2GB

### Recommended
- **RAM**: 2GB
- **CPU**: 2 cores
- **Disk**: 5GB

### With ML Models (torch + transformers)
- **RAM**: 4GB
- **CPU**: 2 cores
- **Disk**: 10GB
