Alias in React Native

There is a point where you will have multiple files and folder in  your project. And we need to get the reference of one file from another in any random possibilities.  If we are following the relative path such as

Your App Root Directory
 |-- app
      |-- component 
      |    |-- login
      |    |   |-- login.js
      +-- resources
      |    |-- icon
      |    |    |-- userupload.png
