Run appropriate package manager (`yarn`, `npm`, or `pnpm`) with single `nn` command

nn.zsh

# run the appropriate package manager
npm-etc() {
  if [[ -f package-lock.json ]]; then
    npm run "$@"
  elif [[ -f yarn.lock ]]; then
    yarn "$@"
  elif [[ -f pnpm-lock.yaml ]]; then
    pnpm "$@"
  else
    echo "Error: Could not detect package manager."
  fi
}

alias nn="npm-etc"

Instead of having to think about which package manager you use per project, append the above gist into your ~/.zshrc and simply use nn command everywhere.

# Example yarn project
> nn install lodash

# Example pnpm project
> nn install lodash
