Minimal express-ws broadcast to all clients

app.js

var express = require('express');
var expressWs = require('express-ws');
var expressWs = expressWs(express());
var app = expressWs.app;

app.use(express.static('public'));

var aWss = expressWs.getWss('/');

app.ws('/', function(ws, req) {
  console.log('Socket Connected');

  ws.onmessage = function(msg) {
    console.log(msg.data);
    aWss.clients.forEach(function (client) {
      client.send(msg.data);
    });
  };
});

app.listen(3444);

V0 uses the syntax in the OP's gist. V1 does not support this, so you'll have to use another approach, such as @freebeans'.

Reason being, V0 used a separate WSS for each route, and V1 does not. The parameter used to specify which WSS to return.

This change actually contributed to the major version change.

GJ!

I create a fork to enable fetching clients from a route like old getWss(route)
