title: ionic2 Angular2 import/export JSON data
body: <p>What I mean by import/export data and why it needs to be implemented..</p>
  
  <p>1) I want my app to work offline - store data added by user while offline.</p>
  
  <p>2) The data stored in JSON format.</p>
  
  <p>3) I want that JSON data to export in a file and stored in phone memory.</p>
  
  <p>4) Multiple files will be created.</p>
  
  <p>5) When user get internet - the exported file will be imported and that JSON object to be stored in datastore - any server like Firebase.</p>
  
  <hr>
  
  <p>Please suggest how this could be possible in Ionic2, Angular2.</p>
  
  <ul>
  <li><p>The JSON object to be export in file - while offline.</p></li>
  <li><p>Later that file will be imported and the data to be save over server.</p></li>
  </ul>
  
  <p>Yet everything is working while online.
  Due to large collection of data AngularFire2 like offline library wasn't working properly.  </p>
  
  <p>Please suggest possibilities..</p>
