# Django Real-Time Sync with WebSocket

> A Django demo of real-time sync: a message sent in one browser tab appears in every other tab, over WebSocket and Redis.

- Category: websocket-sync
- Status: Completed
- Started: October 12, 2025
- Built with: Django, Python, Redis, Whitenoise

## About

### The problem

Most Django tutorials stop at request and response, so developers adding live features often fall back to polling, which is slow, wasteful and hard to scale.

### The approach

I built a focused reference project with Django Channels: the browser opens a WebSocket, joins a channel group, and Redis acts as the channel layer so messages broadcast across processes, not just inside one.

- Instant synchronisation: a message sent in one tab appears in every other tab without a reload.
- Redis-backed channel groups that scale beyond a single worker.
- ASGI configuration ready for Daphne or Uvicorn, with Docker for local setup.

### The result

The repository is a working, minimal template for real-time Django that a developer can read in one sitting and adapt for chat, notifications or live dashboards.

## Features

- **Real-time Messaging**: Synchronizes messages across multiple tabs instantly using WebSocket.
- **WebSocket Communication**: Establishes persistent WebSocket connections for bidirectional data flow.
- **Redis Channel Layer**: Uses Redis to manage channel groups and broadcast messages efficiently.
- **Responsive UI**: Provides a clean and interactive interface for sending and viewing messages.
- **ASGI Deployment Ready**: Configured for production deployment with ASGI servers like Daphne or Uvicorn.
