There is an old thread with some examples but they haven't been updated to the new launcher.
In general Electron adds an overhead and isn't as fast as a native compiler if you mean that. Using Hype shouldn't add that much performance downside specially in the scope of Electron but certainly much value in animations and maybe even interface stuff. Hype isn't that good out of the box with dynamic content and that requires some programming. Using VUE is also a popular choice but that requires also some coding knowledge.
