React Native Can't find variable: window"

Question

Attempting to port a react web project over to native I'm getting the following:

React Native Can't find variable: window"

This is most likely due to me requiring react and attempting to give it global scope with window.React = require('react-native'); .

What's curious is the project runs fine if I enable debugging with chrome.

If the above is incorrect how do I set a global scope with react native ?

Answer 1

React needs to be initialised before the window object can be accessed. Regardless of this in general global is preferred(which is what you would use when developing in node).

Answer 2

downgrade react-native to version 0.55.4 will save your time
