Anyone looking to build their own desktop application with JavaScript, Node and Electron should take a look at bojzi's tutorial:

I chose node-webkit, came to know about Electron later. It was too late to switch. I am going to release my desktop app made in node-webkit soon. It has got its own quirks. But the app development time was fast and I could leverage the nodejs plugins as well as the jquery for the app. I am sure this applies for Electron too.

Electron looks really solid, especially since GitHub is supporting it as open source.
