This might be what you need? https://github.com/AverageMarcus/pusher-websocket-espruino

I'm not sure if Marcus is on the forum or not, but he comes to JSOxford stuff I could probably prod him if you're having problems?

I tried downloading the Pusher.js from GitHub and put it in the sandbox directory, then I uploaded the code from right-hand side of the IDE, but still getting following error,

Uncaught ReferenceError: "Pusher" is not defined
at line 1 col 5
new Pusher(PUSHER_KEY, {}, function(pusher) {

Can anyone help?

require("Pusher");
var PUSHER_KEY = 'XXXXXXXXXXXXX';
new Pusher(PUSHER_KEY, {}, function(pusher) {
  var testChannel = pusher.subscribe('test_channel');
  testChannel.bind('my_event', function(data) {
    console.log('Got a message:', data);
  });
});

Try var Pusher = require("Pusher"); at the top?

I think you might have to ask Marcus who wrote it - maybe file an issue on the Github page?

Looks to me like it's failing here: https://github.com/AverageMarcus/pusher-websocket-espruino/blob/master/pusher.js#L89

It's expecting data from the WebSocket 'open' handler, but the handler will never supply any data. I guess it's possible that he modified the websocket code and never committed his changes.

However: you could try just deleting these 3 lines? https://github.com/AverageMarcus/pusher-websocket-espruino/blob/master/pusher.js#L88-90

Thst might fix it
