react-native-env

Guide on how to set up env for react native

Used for set up:

• Android productFlavors
• IOS scheme
• react-native-config

Warning

• use only "dev" scheme/productFlavor for development, "staging"/"prod" are going to be used while QA/Production
• For iOS only "dev" scheme is debuggable, "stage"/"production" are signed via release configs

How to use

Android

Run on device/emulator (debug mode)

1. npm run react-native run-android --variant=devDebug (uses config from .env.dev)
2. npm run react-native run-android --variant=stagingDebug (uses config from .env.staging)
3. npm run react-native run-android --variant=prodDebug (uses config from .env.prod)

After success build you can see error: Intent { cmp=com.app/.MainActivity } Error type 3 Error: Activity class {com.app/com.app.MainActivity} does not exist

• but it's ok, just launch application on device/emulator**

Assembling build (release mode)

1. npm run react-native run-android --variant=assembleDevRelease (uses config from .env.dev)
2. npm run react-native run-android --variant=assembleStagingRelease (uses config from .env.staging)
3. npm run react-native run-android --variant=assembleProdRelease (uses config from .env.prod)

IOS

NOT use react-native run-ios Running on simulator/real device:

1. Choose schema
2. Run on device/simulator

Assembling build (release mode):

1. Choose schema
2. Run "Product/Archive";

Make changes

Android

• react-native-config - basic link changes (MainApplication.java, settings.gradle, android/app/build.gradle);
• android/app/build.gradle
• proguard-rules.pro

• added app/src/dev/res/values/strings.xml for "dev" productFlavor - for bundle name DEV-app;
• added app/src/stage/res/values/strings.xml for "stage" productFlavor - for bundle name STAGING-app;
• added app/src/production/res/values/strings.xml for "production" productFlavor - for bundle name app;

IOS

• react-native-config - basic link changes (Libraries, Build Setting, Linked Frameworks and Libraries, Build Phases);

• Added new configuration (Staging)

• Added new User-Defined Settings (APP_BUNDLE_ID_SUFFIX, APP_ENVIRONMENT, APP_PRODUCT_NAME)

• Updated Product Bundle Identifier for each configuration (Debug, Staging, Release)

• Added Library Search Paths fix for new configuration (Staging)

• Added Per-configuration build products path fix for new configuration (for "App Target" on tab "Build Settings") (Staging)

• Updated Product Name (Added Prefix)

• Duplicated "production" scheme - called "stage" scheme

• Edited ALL schemes ("dev", "stage", "production"); For each scheme - setting up Pre-actions

• Set up Pre-action script for ALL schemes (Build, Run, Archive):

1. "dev" - ".env.dev"
2. "stage" - ".env.stage"
3. "production" - ".env.production"

• Set up Build Configuration script for ALL schemes (Run, Archive):

1. "dev" - "Debug"
2. "stage" - "Staging"
3. "production" - "Release"
