react-native-quick-start

if macOS 13 and npm 9, please use Node 18 nvm do to realm issues :/

Running

If first time running app, run npm run build:ios or npm run build:android to initially install and build dependencies.

ios

npm run start opens emulator, installs and opens app automatically.

Android

Open desired android emulator and device and enter npm run android. This will begin installation and opening of app.

Included packages

• redux for state management
• realm for persistent data
• ui-kitten for design
• jest for all the testing
• @react-navigation/native for navigation

Prerequisites

machine used for setup was an Intel macOS 13.

ios

1. xcode
   • xcode builds via the xcodebuild command. If command is not found, run xcode-select --install to install xcode-cli.
2. rbenv for managing ruby versions. React-native's default target is 2.7.6
   • rbenv requires additions to PATH for rbenv global [VERSION] to take affect. If necessary add these two lines to the cli profile in use and restart. i.e. .zshrc or .bash_profile.

     export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"

3. cocoapods
   • Use brew install cocoapods to install if not already.
   • cocoapods are used to manage dependencies and packages imported by react-native. pods can be built either by changing directory to ios/ and running pod install or using the build:ios script.

Android

1. Android Studio

   • emulators and devices can also be deployed with the Device Manager of Android Studio.

2. Android Tools

   • Add the following lines to the necessary cli profile (i.e. .zshrc) to export required variables to PATH.

     export ANDROID_SDK_ROOT=$HOME/Library/Android/sdk
export PATH=$PATH:$ANDROID_SDK_ROOT/emulator
export PATH=$PATH:$ANDROID_SDK_ROOT/platform-tools

3. JDK

   • A java development source is required to build for android. You'll need to select the SE Development Kit appropriate for your machine.

4. Gradle

   • If using android studio Gradle plugin will be installed automatically. Gradle is used to build the source code for android. This can be done manually from within android studio, gradlew command, or build:android script.
   • note that in order for Gradle and other plugins to build properly, android studio should be opened at the android folder level of the project, not the src/ level

Debugging

The best tactic for debugging is opening the ios/ and android/ workspaces in their respective editors. This allows to manage SDK versions, build scripts, and more hidden config.

building

Includied are 2 scripts build:ios and build:android. These can be used to manually build either targets without using caches.

ruby

ruby is used to compile the ios version of the app, and has a defined version inside the project that comes default from react-native at 2.7.6. Fixing mismatched ruby versions can be done two ways:

• (Not Recommended) update .ruby-version to local version.
• Use a ruby version manager to install and use a specified ruby version.

Does not use expo!!!
