# simple-websocket-chat

Simple websocket chat demo that uses Redis Pub/Sub for horizontal scaling.

## Requirements

- A running Redis instance.

## Usage

Install the dependences (`npm install`) and then just run the server process as follows:

`$ node src/server.js 8080`

The server will prompt you to connect to a specific URL that will provide the client HTML

interface. By modifying the URL you can authenticate as different users.

Try to spin up multiple instances of the chat server and look how all clients will still

be able to communicate even if connected to different processes.

## Redis Pub/Sub Multiplexing

This example uses [RedisMPX](https://github.com/RedisMPX/) to orchestrate efficiently multiple listeners on top a single Redis Pub/Sub connection.
