Valdi
Valdi is a cross-platform interface roof that compiles directly to local views for iOS, Android and macOS. It offers interfaces written with the declarative TypeScript in local performance without using web view or JavaScript bridge. The roof's toolkits and documents are in beta status since they are in the testing phase in the open source world.

Valdi – A cross-platform UI framework that delivers native performance
“I imagine unpopular opinion, but I don't like the React design or syntax, its adoption was one of the reasons it made me move away from front-end. I'd rather Valdi and other efforts have a different opinionated design and syntax, less over-engineering and more fun.”

“Snapchat also maintains Djinni, used to generate type-safe bindings for C++ code. With Valdi, it seems like they chose to go another route.”
