Couchbase Lite is an embedded NoSQL database designed for iOS, Android, and .Net platforms, providing native platform bindings for Android (Java), iOS (Swift, ObjC), and UWP/Xamarin (C#). For React Native apps, developers must use React Native Modules to access Couchbase Lite’s native APIs from the Javascript environment. The architecture involves a Javascript UI layer common across platforms and a data persistence layer in a native language to interact with Couchbase Lite. The article offers tutorials for both Android and iOS, using a simple app called "Hotel-Finder" to demonstrate accessing and managing data, such as searching for hotel documents and bookmarking them in a local database. Future tutorials are hinted at, including using Cordova plugins for hybrid apps, and the article invites feedback and questions via Twitter, email, or the Couchbase Forums.
