React Native dotenv

Add .env support to your react-native application without including credentials in JavaScript bundle.

Package that loads environment variables from a .env file into process.env. Credentials are not included in the JavaScript bundle, instead credentials that are bundled in the native app are exposed to the Javascript. It's a much more secure way for you application to access credentials, especially when JavaScript bundles are being remotely downloaded. You can easily use .env file and let build process create platform specific configuration files.

NOTE: Android not supported yet, feel free to contribute :)

• In Project navigator right click on project SimpleApp (root item) and choose Add Files to "SimpleApp"
• Add the newly created .env.plist (in MacOS you can show hidden files with ⌘+shift+.)

5. Add Run script in Project Build phases

• It has to be before Copy Bundle resources (see image)

node ../node_modules/react-native-dot-env/cli.js -e ../.env -d $SRCROOT

6. Add to application source code
