# Deploy and Host Sanic WebSocket Chat on Railway

Hello, this is a real-time multi-user chat application built with Python's Sanic framework and native WebSockets. App's features include color-coded usernames, typing indicators, auto-reconnect, chat history persistence, and a responsive dark-themed UI — all in a single file.

## About Hosting Sanic WebSocket Chat

Hosting a WebSocket chat app requires a platform that supports persistent, long-lived connections rather than just traditional HTTP request-response cycles. Sanic's async architecture handles thousands of concurrent WebSocket connections efficiently on a single process. Railway simplifies deployment by auto-detecting the Python runtime, injecting the `PORT` environment variable, and providing a public HTTPS domain with automatic WSS (secure WebSocket) upgrade support — no reverse proxy or TLS configuration needed. Push your repo, and Railway handles the rest.

## Common Use Cases

- Live group chat rooms for communities, classrooms, or team collaboration
- Learning resource for students exploring WebSocket protocols and async Python
- Foundation for real-time features like notifications, live dashboards, or multiplayer game lobbies

## Dependencies for Sanic WebSocket Chat Hosting

- Python 3.10+
- Sanic 23.12.1
- websockets 12.0

### Deployment Dependencies

- [Sanic Documentation](https://sanic.readthedocs.io/)

### Implementation Details

The entire application is a single `app.py` file with the frontend HTML/CSS/JS embedded inline. The server manages connected clients via an in-memory dictionary and broadcasts messages through `asyncio.gather`. The entry point reads Railway's `PORT` environment variable:

```python
port = int(os.environ.get("PORT", 8080))
app.run(host="0.0.0.0", port=port, auto_reload=False)
```
