While doing my normal googling to figure out how other people were managing their config in their react native projects, I came across two seemingly popular methods that I unfortunately just did not click with. So I ended up creating my own workflow for managing and changing between environments.
Firstly I discovered react-native-config, it seemed great and boasted a 12-factor approach, however it just seemed a bit complex for what I was looking for (called me lazy) I didn't want configure something in 2 different way for both iOS and Android.
