title: Angular Import/Export modules in shared Module or Import in Multiple Modules
body: <p>I am restructuring Angular application and I need to clarify some stuff.</p>
  
  <p>I am using modular structure (Core, Shared, etc). There are some common modules which used almost everywhere for ex CommonModule, FormsModule and many others. Practically I need to understand which approach would be more... native options are:</p>
  
  <ol>
  <li><p>To include these modules into the Shared module import, exports arrays (thus they can be used everywhere where I import shared module.</p></li>
  <li><p>To import common modules in all submodules.</p></li>
  </ol>
  
  <p>Which approach to use?</p>
