If you're an aesthetic developer who keeps all projects in a single developer like I do at ~/Developer, this script will help you to clean cached dependencies of your projects and clean some space~

clean.sh

cleaner() {
  # my DEVSPACE is ~/Developer, set your own DEVSPACE and add it to
  # your ~/.zshrc or ~/.bashrc file to let this script detect it
  # check if DEVSPACE is set, if not, set it to the current directory
  if [ -z "$DEVSPACE" ]; then
    DEVSPACE="$(pwd)";
  fi
  # change current directory to DEVSPACE
  cd $DEVSPACE;
  # loop through project folders in current path and ...
  for folder in $(/usr/bin/find . -type d -maxdepth 1); do
    # if package.json exists, delete node_momodules folder
    if [ -f "$folder/package.json" ]; then
      echo "Deleting node_modules folder in $folder"
      rm -rf "$folder/node_modules"
    # if cargo.toml exists, delete target folder
    elif [ -f "$folder/Cargo.toml" ]; then
      echo "Deleting target folder in $folder"
      rm -rf "$folder/target"
    fi
  done
}
