A cross-platform UI framework with native performance
About
- Valdi, made by Snap (Snapchat), is a cross-platform UI framework that delivers native performance on iOS, Android, and macOS, compiling UIs written in declarative TypeScript directly into each platform's native views
- Works without web views or a JavaScript bridge, and maintains high performance through automatic view recycling, an optimized layout engine, viewport-based rendering, and more
- Speeds up development with instant hot reload, VSCode debugging, and TSX syntax support, and also flexibly supports integration with existing native apps
- Provides deep native integration through type-safe bindings between TypeScript and native code, protobuf support, and integration with C++, Swift, and Kotlin
- A technology proven in Snap's production apps for 8 years, it is a scalable foundation for UI development that includes advanced features such as large-scale animation, gestures, and multithreaded processing
