Hello All,

const es = require('../../../style/vendors/EventSource');
es.EventSource(SERVER_URL);

Firstly , i am not able to see that EventSource.protoype getting called which is inside EventSource.js
and secondly, when using es.addEventListener i am getting

TypeError: es.addEventListener is not a function

 es.addEventListener('open', function (event) {
console.log('event source open');
 });
