Are there performance trade-offs with DOM components?

Yes, webviews add overhead compared to native components. They should be used for specialized content or web-only features rather than building entire app screens.

How do I communicate between native code and a DOM component?

You can pass data via serializable props (strings, numbers, objects) and expose native functionality by passing async functions as props to the DOM component.

What does the 'use dom' directive do?

The 'use dom' directive tells the Expo bundler to render that specific React component within a webview on native platforms (iOS/Android) while rendering it as a standard component on the web.

Can I use web libraries like Recharts in React Native?

Yes, by using this skill to implement DOM components, you can run web-only libraries like Recharts, Chart.js, and more inside your Expo app without modification.

Mobile Development

Integrates React web code and web-only libraries into Expo and React Native applications using DOM components.

The use-dom skill provides specialized guidance for implementing Expo's DOM components, enabling developers to run web-centric code verbatim within native environments. This is essential for using DOM-dependent libraries such as Recharts, syntax highlighters, or rich text editors that lack native equivalents. The skill covers the 'use dom' directive, managing serializable props, bridging native actions to webview contexts, and ensuring smooth integration with Expo Router, allowing for an incremental migration path from web to native mobile platforms.
