React native changing variable in release build [duplicate]

Question

In my app I have to use different API endpoints depending on the type of build. Up till now I was always changing the api variable manually before each build, but now I wan't to see if this can be automated. Has anyone come up with a simple solution to this? I imagine this to be a check when the app is bundling, and if say the build is 'release', the api variable should be X.

There are very nice libraries that solve this problem, such as github.com/luggit/react-native-config — nbokmans

Not sure if it's a good idea but you can use __DEV__ global variable in JavaScript to determine if you're using React Native packager or not

const randomVar = __DEV__ ? 'devValue' : 'releaseVal';
