react-native login
Blog post about integrating Facebook SDK with react-native here.
Note: To get this project running, you need to install the Facebook SDK for iOS!
Check out the example gif below (sorry it's a bit heavy) to see it in action. Note that it is in the simulator so it uses the browser for Facebook auth; it will use the Facebook app if it is available. Video background is implemented with react-native-video, the gradient for the button with react-native-linear-gradient, and the 'About this project' modal with react-native-modal.
background.mp4 does not belong to me, I borrowed it from airbnb.com
