Application Specific Setup

🤖 Terminal

Run the following in the Terminal to avoid showing the computer name for every prompt. The command will create a .zshrc file in the user root folder. In between the single quotation marks you can add whatever you prefer. Restart the Terminal for the changes to take effect.

echo "export PS1='→ '" >> ~/.zshrc

🤖 npm

[sudo] npm i -g epic-cli epic-cli provides useful everyday commands.

- Prettier

Sourcetree

Ignore connecting during startup and then go to the Remote tab and click connect. Add your GitHub account, which will automatically connect when you're already logged in in the browser. Logging into GitHub in Chrome make sure to remove existing SSH keys from old installations. Back in Sourcetree generate a new SSH key and Save. Checking out won't work until the authenticity of github.com has been confirmed. This can be done in the Terminal and by cloning any repository (install developer tools when prompted)

git clone git@github.com:[username]/[repository].git [destination-folder]

enter yes to add GitHub to known hosts. The following command will ensure the key is available when committing.

ssh-add --apple-use-keychain ~/.ssh/[GitHub-Username]-GitHub

The SSH key generated by Sourcetree will only be valid for the current session. To push or checkout with Sourcetree run the above again in Terminal after every restart or logout. To avoid running it after every restart it's also possible to add it to .zshrc after which the key will be available once the Terminal has opened. Use sudo vim ~/.zshrc to edit this file, which has already been created and appended by the run.sh script.

# Load SSH key.
ssh-add -q --apple-use-keychain ~/.ssh/[GitHub-Username]-GitHub

Usage

Press ⌘⇧. to show hidden files temporarly in Finder.

React Native

Download and open XCode from App Store.
React Native can work with the preinstalled version of gem but upgrading doesn't work well. To avoid this install homebrew and then run brew install rbenv ruby-build to install the Ruby environment manager. Run rbenv install -l to list the newest stable release and install it with rbenv install X.Y.Z and apply it with rbenv global X.Y.Z.
- Add the following lines with sudo vim ~/.zshrc to the file and restart the Terminal.
- Check if the switch was successful with ruby --version.

# Add rbenv Ruby to path.
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
# Add gems to path.
export GEM_HOME="$(ruby -e 'puts Gem.user_dir')"
export PATH="$PATH:$GEM_HOME/bin"

Install Cocoapods gem with gem install cocoapods --user-install and update all gems with gem update. Also, run gem update --system to update gem itself.
Download and install AndroidStudio Android IDE.
- Use Android Studio to open the /android project folder from a React Native installation.
- Update dependencies in the SDK Manager (icon in top-right). When using numic make sure to install the CLI tools.
- Add a new Virtual Device in the Device Manager.
- Add below binaries (includes adb) to path with sudo vim ~/.zshrc.

export ANDROID_HOME=$HOME/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools
# Use Java bundled with Android Studio.
export JAVA_HOME=/Applications/Android\ Studio.app/Contents/jbr/Contents/Home
# Required by flipper debugger.
export ANDROID_SDK_ROOT=$HOME/Library/Android/sdk

Update Native Android Installation

The default gradle version from the react-native installation will only work with very old Java versions.

Update gradle to newest version in Gradle Releases and Google Maven for build.gradle
- File android/build.gradle
- and android/gradle/wrapper/gradle-wrapper.properties
