It would be nice if Microsoft would enable a type of language server scheme, like they use for VS Code, to allow Electron apps to use any backside language rather than depending on Node. Would be handy to have a cross-platform app where the UI is HTML/CSS/JS but the core logic was in Go or Ruby or C# or (insert language here).

There are some technologies like this. I'm going to look into Wails: https://github.com/wailsapp/wails
