title: Firebase for react and react native
body: <p>I'm planning to write a cross platform app using react native using Firebase for backend. I did some research and found the library called React-Native-Firebase. But this library seems to use native part of firebase(android and ios), and my concern is:</p>
  
  <p>If I use React-Native-Firebase to do backend jobs, will I need to write those logics AGAIN using normal Firebase(web version) for building web app with react?</p>
  
  <p>I thought this way because using firebase seems basically like calling Firebase API's in react native or react code.</p>
