What is the Expo Modules API?

It is a modern framework for writing native code in Swift and Kotlin for Expo and React Native apps, utilizing a high-performance JSI (JavaScript Interface) instead of the traditional bridge.

What are Shared Objects in Expo?

Shared Objects are native class instances that can be shared directly with JavaScript, allowing you to maintain complex native state across component lifecycles.

Can I use this skill to build UI components?

Yes, it includes specific standards for building native Views with APIs inspired by modern web libraries like Radix UI and Base UI.

Does this skill support legacy React Native architecture?

No, this skill is strictly focused on the New Architecture and the Expo Modules API to ensure modules are future-proof and performant.

Mobile Development

Guides the development of high-performance Expo native modules using modern JSI-based architecture and web-standard API patterns.

This skill provides specialized guidance for building robust native modules within the Expo ecosystem for iOS and Android. It emphasizes the use of the modern Expo Modules API, Swift, and Kotlin, moving away from legacy React Native bridges. By following patterns for Shared Objects, Marshalling-style APIs, and W3C-inspired interface design, developers can create native extensions that are highly performant, type-safe, and seamlessly integrated with the Expo router and configuration plugins.
