title: How to fetch data from a different firebase project?
body: <p><strong>Scenario</strong> I have created two projects in firebase using command line tools. The first site(say A) is a web-app that uses hosting, firestore, cloud functions and auth. The second site(say B) is sort of admin-portal which should be able to show all the data in site-A. Site-B uses different Auth than site-A.</p>
  
  <p><strong>Note</strong> More sites like site-A will be created in future and site-B will remain the admin-portal of all of them.</p>
  
  <p><strong>Question</strong> How to bring the data from one project in firebase to some other project?</p>
  
  <p><strong>PS</strong> I know that SO doesn't allow this but if there is a better way of doing this, I would be very happy to know.</p>
