There are many situations where you want to connect to a Node.js instance running on a remote server. Currently, I have a RaspberryPi running with input from a light sensor. It’s very helpful when debugging, to be able to step through the code running on the hardware directly.
The RaspberryPi is already on my local network. I connect to the device over ssh and start the app, then step through the code on my local machine using DevTools.
