Communicating with Client WebSockets

In some rare situations, you may have the need to communicate with the attached WebSockets in the browser. To accomplish this, open a new WebSocket to the server, and send a broadcast message. eg.

const stringify = require('json-stringify-safe');
const { WebSocket } = require('ws');

const socket = new WebSocket('ws://localhost:8081'); // this should match the server settings
const data = {
  type: 'broadcast',
  data: { // the message you want to broadcast
    type: '<something fun>', // the message type you want to broadcast
    data: { ... } // the message data you want to broadcast
  }
};

socket.send(stringify(data));

Note: The data property of the message should contain the enveloped message you wish to broadcast to all other client WebSockets.
