Electron app with auto-update, do as much of the updating as possible while app is still open

[Jaifroid]

Many Electron apps keep a small window open so that the user can see whether the app has finished updating or not. This is important, because otherwise the user may restart the app while it is installing, which can lead to ugly failures.

There is sample code for this somewhere on the Electron Builder site. I just need to find and apply it.

It seems this isn't easy to implement. A better solution would be to allow the update to initiate while the app is still open, and to complete fully when shut down. Changed title to reflect this.
