Can I use any web library with this skill?

Yes, DOM components allow you to use libraries that depend on DOM APIs, such as Recharts, Chart.js, or React Syntax Highlighter, which are typically incompatible with standard React Native.

How do DOM components communicate with native code?

Communication is handled by passing asynchronous functions as props to the DOM component, allowing the web code to trigger native actions like alerts or storage updates via a bridge.

What are the limitations of props in DOM components?

Props passed to DOM components must be serializable, meaning you can only pass strings, numbers, booleans, arrays, and plain objects. Functions must be asynchronous.

What is a DOM component in Expo?

A DOM component is a React component that uses the 'use dom' directive to run web code inside a WebView on native platforms while rendering normally on the web.

When should I avoid using DOM components?

Avoid them when native performance is the top priority, for simple UI layouts that React Native can handle efficiently, or for core navigation files like Expo Router _layout.tsx files.

Integrates web-based React components and libraries into native Expo applications using the 'use dom' directive.

This skill enables Claude to implement and manage Expo DOM components, allowing developers to seamlessly bridge the gap between web and native environments. It facilitates the use of web-only libraries—such as complex charting engines, rich text editors, and syntax highlighters—within native apps by rendering them in a controlled WebView on iOS and Android while maintaining standard rendering on the web. This is ideal for incremental migrations, rendering complex CSS layouts, and accessing web-specific APIs like Canvas or WebGL that are not natively available in React Native.
