Architecture

Follow an app from TypeScript source to a native screen. These pages explain implementation choices for contributors and help app authors diagnose behavior that spans the compiler and runtime.

Kuito compiles TSX into native-view descriptions and reactive bindings. App logic runs in Hermes inside the native process. UIKit or Android Views render the result using a shared layout engine.

Live Patch updates a running development app after a source edit. It retains compatible component state and native views so you can continue the interaction you are testing.

Use this page when changing event delivery, the native boundary or frame scheduling. A JavaScript job collects view changes into a typed batch; the UI thread applies committed batches in order.

The renderer applies Kuito's typed mutations to UIKit and Android Views. Use this page when adding a primitive, property, event or child-hosting view.

Kuito automatically omits native objects for containers used only for layout. Their layout nodes remain, so spacing and flex behavior are preserved. Use this page to understand why a layout wrapper is absent from a…

Kuito executes app JavaScript inside the iOS or Android process. The desktop development server compiles and sends updates; it does not run the app's event handlers on behalf of the phone.
