JS UI

JS UI lets you render native mobile interfaces from JavaScript. There are two supported authoring levels:

• React with @napps/nodes is the recommended approach for application components.
• Direct JSI nodes are available when you need to control the native tree yourself or integrate another renderer.

​

Recommended path

Start with React UI. It provides JSX, component composition, hooks, styling helpers, animations, gesture handling, Fast Refresh, and React DevTools support. Use the React subpages to learn about:

• Hooks
• Styling
• Animations
• Gestures
• Nodes

For a runnable set of patterns, see UI examples.

Direct integration

Direct JSI nodes documents RootNode, UIContainer, UINode, node operations, and the native tree lifecycle.
