title: Firefox, Safari, Edge not loading JS file using require()
body: <p>I have a React app and have installed <code>annyang</code>.</p>
  
  <p>I am calling this at the top of my file using 
  <code>const annyang = require('annyang');</code></p>
  
  <p>In Chrome if I <code>console.log(annyang)</code> it returns an object but in all other browsers it returns null.</p>
  
  <p>Why is this happening in all browsers except Chrome and how can I fix it?</p>
