KatyRosli / ReactNative-LemonApp

Little Lemon App

• An Mobile App that enables Users to navigate between screens and enter valid email address to subscribe to the newsletter.

Built with 🛠️:

• React Native
• JavaScript

Prerequisites

• Node.js > 12 and npm (Recommended: Use nvm)
• Watchman
• Xcode 12
• Cocoapods 1.10.1
• JDK > 11
• Android Studio and Android SDK

Using React-Native

Keep in mind that this library can cause trouble if you are renaming a project that uses Pods on the iOS side.

After that you should proceed as with any javascript project:

• Go to your project's root folder and run npm install.
• If you are using Xcode 12.5 or higher got to /ios and execute pod install --repo-update`
• Run npm run ios or npm run android to start your application!

(Using yarn: yarn ios or yarn android)

Note: Please read the Setup environments section that is below in this file for more information about the execution scripts.

Using scripts from console

The template already has scripts to execute the project calling a specific environment defined into the package.json file. Keep in mind that if you are going to create new envs you have to define the script to build the project properly.

To define which env you want to use, just keep the structure yarn [platform]: [environment]

DEV: yarn ios or yarn android

STG: yarn ios:staging or yarn android:staging

PROD: yarn ios:prod o yarn android:prod

Also, you can use npm following the same rule as before: npm run ios:staging

Modify the environment variables files in root folder (.env.development, .env.production and .env.staging)

Android

A map associating builds with env files is already defined in app/build.gradle you can modify or add environments if needed.

For multiple enviroments to work you would need to change -keep class [YOUR_PACKAGE_NAME].BuildConfig { *; } on proguard-rules.pro file.

iOS

The basic idea in iOS is to have one scheme per environment file, so you can easily alternate between them.

To create a new scheme:

• In the Xcode menu, go to Product > Scheme > Edit Scheme

• Click Duplicate Scheme on the bottom

• Give it a proper name on the top left. For instance: "qa"

• Then edit the newly created scheme to make it use a different env file. From the same "manage scheme" window:

  Expand the "Build" tab on the left menu

  • Click "Pre-actions", and under the plus sign select "New Run Script Action"
  • Where it says "Type a script or drag a script file", type: echo ".env.qa" > /tmp/envfile replacing .env.qa with your file.

• Also, you will need to select the executable for the new schema:

  Expand the "Run" tab on the left menu

  • Under the "Executable" dropdown select the ".app" you would like to use for that schema

Generate production version

These are the steps to generate .apk, .aab and .ipa files

Android

1. Generate an upload key
2. Setting up gradle variables
3. Go to the android folder
4. Execute ./gradlew assemble[Env][BuildType]

Note: You have three options to execute the project assemble: Generates an apk that you can share with others. install: When you want to test a release build on a connected device. bundle: When you are uploading the app to the Play Store.
