How to install NodeJS on Debian/Ubuntu systems using Ansible

Since I’ve had to figure out how to do this twice now, and the NodeSource instructions make this more confusing than it ought to be. Make sure you replace node_6.x with the appropriate version from the installation instructions and xenial with the results of lsb_release -s -c.

- name: NodeSource package key
  apt_key:
    state: present
    url: https://deb.nodesource.com/gpgkey/nodesource.gpg.key
- name: NodeSource repository
  apt_repository:
    repo: 'deb https://deb.nodesource.com/node_6.x xenial main'
- name: Install NodeJS
  apt:
    state: present
    name: nodejs
