Summary

Expo has introduced a new set of development tools plugins for the Expo CLI, marking a shift away from Flipper, which no longer has first-party support in React Native. These plugins, available with Expo SDK 50, are designed to be easy to use and develop, and are housed in the expo/dev-plugins repository. By adapting existing Flipper plugins and third-party tools, Expo has streamlined the migration process, avoiding the need for complete rewrites. The core structure of these dev tools includes an App Adapter, a Web UI, and a Communication Message Bus using WebSocket for interaction between components. A significant challenge was transitioning the Web UI from Flipper's sophisticated React-based components to a broader web technology environment, allowing developers to leverage any web technology for dev tool UI creation. The initiative encourages community participation, offering tools to create custom plugins and inviting feedback to enhance the developer experience, with special recognition given to the foundational work of Flipper plugin creators.
