React Native has empowered web developers everywhere to bring their skill set to the mobile environment. But mobile apps have different needs than React-based web apps—most notably, they go offline all the time. For developers that want their users to be able to share and collaborate even while offline, the only options have been endless lines of code dedicated to cache refresh logic and conflict resolution. In this live coding session, Maxime Beugnet, Senior Developer Advocate at MongoDB, will demonstrate how to build a simple mobile application using the Realm’s React Native SDK and synchronize data across different devices with Realm Sync even during extended offline periods!
