Shell function to initialize a Node.js project: creates a folder under ~/projects, generates an index.js file, initializes npm and Git, creates a .gitignore, makes an initial commit, and opens the file in VS Code.

initnpm.sh

initnpm() {
  if [ -z "$1" ]; then
    echo "Usage: initnpm <project_name>"
    return 1
  fi

  mkdir -p ~/projects/"$1" && cd ~/projects/"$1" || return 1

  echo "// entry point" > index.js
  npm init -y > /dev/null
  echo "node_modules/" > .gitignore

  git init > /dev/null
  git add .
  git commit -m "initial commit" > /dev/null
  git branch -M main 2>/dev/null || git branch -m main 2>/dev/null

  code -g index.js

  echo "Project '$1' successfully created and index.js opened in VS Code."
}
