AH HA! So turns out you need to install as root - the regular pi user doesn’t have enough permissions to install socket.io which is a dependency of electron…

The manual install instructions should be updated to state

sudo npm install
npm start

That is actually one of the use case i am covering with my app and BLE module:

One of the features is, that you can connect a MagicMirror to a wifi network over bluetooth.
Only downside is, that there is currently only an app for Android and not for IOS or Windows Phone (i currently have neither, so can’t develop one in the near future).
