# Example app using react-native-config
Just a single app accessing config variables from `.env` and `.env.prod`.
## Running in Android
By default it will read variables from `.env`:
```bash
$ react-native run-android
```
To read from another file just specify it with `ENVFILE`, like:
$ ENVFILE=.env.prod react-native run-android
## Running in iOS
Open the Xcode project file in `Example/ios/Example.xcodeproj`.
Notice there are two schemes setup for the application: "Example" runs the default build, reading vars from `.env` – and "Example (prod)" is configured to read from `.env.prod`.
