In an article detailing the integration of Ditto's resilient mobile database with Expo Development Builds for React Native, the introduction of a new Expo plugin is highlighted as a significant advancement for developers. This plugin automates many manual setup steps typically required by React Native CLI users, such as updating Info.plist and AndroidManifest.xml with necessary permissions and configurations. By utilizing native modules, the plugin facilitates real-time, peer-to-peer synchronization in Expo apps without the need for manual configuration, thus streamlining the development process. The article emphasizes the benefits of this approach in saving developers time and effort while ensuring a clean and idempotent configuration, and it also acknowledges the support from the Expo team in enhancing the flexibility and compatibility of the plugin. Detailed setup instructions and a reference project, the RN Expo Quickstart app, are provided to help developers quickly integrate and test the SDK in a real device environment, allowing them to focus on building rich user experiences.
