title: Use Moment.js in extjs project
body: <p>I'm developing an Extjs project using 6.5.2 version and modern toolkit, i want to use <a href="https://momentjs.com/" rel="nofollow noreferrer">https://momentjs.com/</a> package but i couldn't import the node_dependency. 
  The Momentjs page has the downloads or install methods, but if i download the code, where i want to use whatever method, this throw an exception and if i install the package using 'npm install moment --save' command, i don't know how to import and call it.</p>
  
  <p>Someone can help me importing this dependency in extjs.</p>
