title: How to make my angular application lightweight
body: <p>I am using angular 7 in my application.</p>
  
  <p>When I have started the application using localhost:4200 in developers tools network tab too many CSS, scss, js...... are loading.
  But I don't need to load all of them. I need only the login module and corresponding styles...
  So that my application will work very fast.</p>
  
  <p>How to do this?</p>
