title: React Native: Make a native library
body: <p>I have made an App and successfully made a bridge and integrated native code.</p>
  
  <p>Now I  want to make a native library in React-Native, which includes ios and android code.
  I tried many websites and there isn't much online resource for it.</p>
  
  <p>Right now, 
  Everything is working. 
  But now I want to make it as an npm module and make the <code>react-native link</code> command or <code>pods</code> work.
  In this process, I already know the npm procedure. But I don't know how the linking works.
  Same with android, I want the <code>react-native link</code> to work as well.</p>
  
  <p>Is there any resource where I can find a good approach to this.</p>
