Make Node.js websocket client run indefinitely

Question

I'm using ws library to handle Websocket connections client-side.

Here's example from ws docs (https://github.com/websockets/ws#usage-examples):

const WebSocket = require('ws');

const ws = new WebSocket('ws://www.host.com/path');

ws.on('open', function open() {
  ws.send('something');
});

ws.on('message', function incoming(data) {
  console.log(data);
});

The problem is that this program exits after receiving just the first message from server.

How do I make it run and listen for messages indefinitely?
