TypeError: __webpack_require__.g.ActiveXObject is not a constructor

I use centrifuge to connect to DonationAlerts server and everything works fine until I get to 3rd step where Centrifuge has to send POST ajax request to DA endpoint in order to get channel subscription token.

This is my code:

centrifuge.subscribe('$alerts:donation_235774', function(message) {
    console.log('new message', message)
});

And I get error:

TypeError: __webpack_require__.g.ActiveXObject is not a constructor

Looks like it only happens when channel name starts with $ character. I tried alerts:donation_235774, news — no errors. But as soon as I add $ before anything — it breaks. Also tried aasd$asdas and no errors thrown.

OS: MacOS Big Sur 11.0.1 Version of Centrifuge-js: 2.7.5 NodeJS version: v15.2.1 NPM version: 7.0.10 I use WebSockets for nodejs, also tried with sockjs and it couldn’t even connect to server

Cool, looks like we need to add explicit option to pass it into Centrifuge like we have with WebSocket and mention in readme.

Hello, try to add https://www.npmjs.com/package/xmlhttprequest to dependencies of your NodeJS project and then:

const Centrifuge = require('centrifuge');

global.WebSocket = require('ws'); 
global.XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;

var centrifuge = new Centrifuge('ws://localhost:8000/connection/websocket')

Thanks! Works perfect
