There's a lot of discussion in the comments here about Electron vs. native apps. But last year's Catalyst project, which allows you to ship iOS-based projects on the Mac, opens an important new path. I've been surprised not to see many people discuss it!

In particular, this means that you can use React Native to build native macOS apps. You still get live reloading, hot code push, pleasant abstractions, etc. Most importantly, though, these apps can use straight-up AppKit controls on macOS and straight-up UIKit controls on iOS. Better still, you can use react-native-web to ship such projects on the web too.

You will+should, of course, have many platform-specific branches. But I find that the vast majority of my code is shared, and there's a _world_ of difference in being able to use the same development tools to ship polished software on desktop, mobile, and web.

My most recent project builds to macOS, iOS, Android, and web out of the same Typescript project. There was certainly some toolchain chicanery involved in this, but now that it's set up, it's delightful.

Many of the companies shipping Electron apps on desktop are shipping React Native apps on mobile. I would very much like to see React Native-based desktop apps replace Electron apps.
