### Install node locally
To install and manage `node` as a local user we are going to use [Node Version Manager](https://github.com/nvm-sh/nvm) as an established solution to installing and managing multiple versions of node without needing `root` access. We are going to install the `lts` or long term support release of `node` to use with this application.
