If you want to run commands periodically (say, more than once every few minutes), you should consider running the HTTP server, which opens a connection to the backend at startup and reuses it for all commands sent to it. The HTTP server will (eventually) support all the commands that the CLI tool supports.
This will install the easy-server CLI tool in the /usr/local directory (npm config get prefix will show you where). This library requires Node.js 6.0.0 or later!
