# Python Backend Rewrite Complete
|
|
|
|
## Summary
|
|
Successfully rewrote the Node.js/TypeScript backend to Python with VK Music integration.
|
|
|
|
## New Python Backend Structure
|
|
```
|
|
├── main.py # Entry point - FastAPI app with uvicorn
|
|
├── requirements.txt # Python dependencies
|
|
├── setup.py # Environment setup script
|
|
├── backend/
|
|
│ ├── __init__.py
|
|
│ ├── database.py # SQLAlchemy models and database connection
|
|
│ ├── vkmusic.py # VK Music API integration (replaced SoundCloud)
|
|
│ ├── api.py # FastAPI routes and endpoints
|
|
│ └── bot.py # Telegram bot functionality
|
|
├── Dockerfile # Updated for Python
|
|
└── .env # Environment variables (created by setup.py)
|
|
```
|
|
|
|
## Key Changes Made
|
|
1. **Framework**: Express.js → FastAPI
|
|
2. **Music Service**: SoundCloud → VK Music (vk-api library)
|
|
3. **Database**: Direct PostgreSQL → SQLAlchemy ORM
|
|
4. **Bot**: node-telegram-bot-api → python-telegram-bot
|
|
5. **Audio Processing**: fluent-ffmpeg → subprocess + FFmpeg
|
|
|
|
## API Endpoints (Preserved)
|
|
- `GET /` - Serve main HTML with cache-busting
|
|
- `POST /api/search` - Search VK Music tracks
|
|
- `POST /api/convert` - Convert audio to MP3
|
|
- `POST /api/telegram-send` - Send audio via Telegram
|
|
- `GET /health` - Health check
|
|
- `GET /downloads/{filename}` - Serve MP3 files
|
|
|
|
## Environment Variables Required
|
|
- `DATABASE_URL` - PostgreSQL connection string
|
|
- `VK_LOGIN` - VK account login
|
|
- `VK_PASSWORD` - VK account password
|
|
- `TELEGRAM_BOT_TOKEN` - Telegram bot token
|
|
- `WEB_APP_URL` - Web app URL for bot
|
|
- `PORT` - Server port (default: 8000)
|
|
- `HOST` - Server host (default: 0.0.0.0)
|
|
|
|
## Setup Instructions
|
|
1. Run `python setup.py` to initialize environment
|
|
2. Update `.env` file with actual credentials
|
|
3. Install dependencies: `pip install -r requirements.txt`
|
|
4. Start server: `python main.py`
|
|
5. Access API at: http://localhost:8000
|
|
|
|
## Docker Support
|
|
Updated Dockerfile uses Python 3.11-slim with ffmpeg support. Ready for containerized deployment.
|
|
|
|
## Next Steps
|
|
- Test VK Music integration with actual credentials
|
|
- Update frontend if needed to work with new Python API
|
|
- Deploy and test in production environment |
