React Native

General

Prettier, eslint and jest have been removed from the package.json. This roughly halves the number of dependencies that were being installed. There were only a handful of React Native specific eslint rules so the loss might not be a big deal? Also need to see if vitest can be used to replace what jest was doing.

Running npx react-native doctor can find issue in the dev environment.

iOS

MacOS: Ruby needed to be updated to 3.3.0. The following config also added to .zshrc source /opt/homebrew/opt/chruby/share/chruby/chruby.sh source /opt/homebrew/opt/chruby/share/chruby/auto.sh chruby ruby-3.3.0

Ensure cocoapods is installed.

If cloning from scratch or switching to a new git worktree the cocoapods need reinstalling before pnpm start will work.

First cd in the ios folder and then bundle install && bundle exec pod install

Android

Java 17 was needed. SdkMan was used instead of brew.

curl -s "https://get.sdkman.io" | bash

source "/Users/nigelb/.sdkman/bin/sdkman-init.sh"

sdk install java 17.0.9

sdk list java

sdk install java 17.0.9-tem

java -version => 17.0.9

Also ensure the Android SDK Command Line Tools are installed via the Android Studio SDK manager.

After setting up Android Studio and an emulator the following is needed in .zshrc

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

Remember to source ~/.zshrc after, or open a new terminal. Without this pnpm start will fail to first launch the emulator and then fail to launch the react native app, even though it will install it successfully.

NOTE: I didn’t have time to root cause this, but after cloning from scratch the Android project was missing some dependencies. Maybe the original init did some magic? I fixed these manually by

pnpm add -D @react-native-community/cli-platform-android @react-native/gradle-plugin
