title: Running Ionic 2 App
body: <p>I am new to Ionic 2. I cloned one project from github for learning purpose and I am trying to run it locally. Following are the steps that I have used to run the app.</p>
  
  <pre><code>1)npm install 
  2)ionic serve
  </code></pre>
  
  <p>The original repo was 9MB. After running "npm intall", it creates node_module directory which is more than 200mb. Is there any way to not to have node_module and run app without it? </p>
  
  <p>By running this command it also creates www folder which was not in original repo. Is www required for ionic 2 app?</p>
  
  <p>My second question is how to generate apk file in ionic2? Will my apk file will also have node_module and will it be really large file?</p>
