title: Why my Polymer2 build size is large as compared to Angular5 build?
body: <p>To choose <code>polymer2</code> over <code>angular</code> framework, because I read from some blogs that polymer contribute less build size for prod as compared to angular2/5 build,</p>
  <p>I have created two demo projects one for angular5 and second for polymer2.</p>
  <p>For angular5 I run</p>
  <blockquote>
  <p><code>npm new angular5-demo --service-worker --routing</code></p>
  </blockquote>
  <p>and for polymer2</p>
  <blockquote>
  <p><code>polymer init</code></p>
  <p>Press the down arrow until polymer-2-starter-kit is highlighted and press the enter / return key to select.</p>
  </blockquote>
  <p>and when i'm running projects by</p>
  <p><code>ng serve --prod</code> and
  <code>polymer serve --open</code></p>
  <p>and it's showing large size of polymer project as compared to angular</p>
  <blockquote>
  <p>transfered data:</p>
  <p>angular : 60-70kb</p>
  <p>polymer : 50-204kb</p>
  </blockquote>
  <p>rencenty i went though a many blogs for polymer and they are claiming that polymer build size is 4-5 times less as compared to angular</p>
  <p>one blog link is mentioned <a href="https://medium.com/@realabhijeet4u/angular-2-0-vs-polymer-f45a4f539238" rel="nofollow noreferrer">here</a></p>
  <p>So, is there something i'm missing to build for prod in polymer project from polymer site.</p>
  <p>please help me to find out the issue.</p>
