ws-multipath

ws-multipath is a wrapper around websockets/ws that provides the ability to attach multiple WebSocket servers to one shared HTTP server to handle multiple paths.

Why?

Have you ever wanted to serve multiple WebSocket endpoints using a single port/server. You might have tried something that looked a little bit like this:

const { Server } = require('ws');
 
const PORT = 1234;
 
const server1 = new Server({ port: PORT, path:'/notifications' });
const server2 = new Server({ port: PORT, path:'/messages' });

Soon after, you realize that it's not possible. Not easily, at least.

Having multiple WebSocket servers on the same port can be a messy process. So I decided to write ws-multipath in hopes of simplifying this task.

How?

In order to have multiple WebSockets server running on the same port, a developer would have to create multiple "serverless" WebSocket.Servers (using the noServer option) and utilize one shared HTTP server that delegates requests to the proper WebSocket server.

Sounds complicated, right? That's all what ws-multipath does!

Example

const MultipathServer = require('ws-multipath');
 
const server = new MultipathServer({ port: 1234 });
 
const foo = server.createHandler({ path: '/foo' });
const bar = server.createHandler({ path: '/bar' });
 
// handle sockets connecting to ws://localhost:1234/foo
foo.on('connection', (ws) => {
  ws.send('hello from /foo!');
});
 
// handle sockets connecting to ws://localhost:1234/bar
bar.on('connection', (ws) => {
  ws.send('hello from /bar!');
});
