react-native-oauth-demo | React Native Oauth2 demo application

Every login provider will require some setup. For Google, this is what you need to do:.
Create a new project in Google APIs developer console
After you have selected a name, you need to wait a couple of minutes for the project to be created
Go to the API credentials screen
Select "Create credential" > "Oauth client" and select Application type "Web application"
Authorized redirect URIs are the most important. For now, let's just configure localhost. We need the redirect URIs to specify which login provider we're dealing with, so http://localhost:8084/oauth2proxy/google/oauth2callback is a good redirect URI
When you complete the registration, you will get a client id and a client secret. At first we will need to save the client id to a file named env.js: GOOGLE_CLIENT_ID=...
We will use React Native Config to handle the configuration. Run npm install react-native-config --save-dev to install it, and put the line react-native link react-native-config to install the platform modules.
