Building a Video Calling App Using the Agora SDK on Expo (React Native)

Expo SDK 42 enables customization of native runtime for apps using custom development clients, allowing use of libraries with native code without resorting to bare workflow. This feature is easy to set up and start using. However, it cannot be tested with the Expo Go app and requires setting up Android Studio or XCode. Node.js LTS release, Git, Yarn, and Expo CLI are required for installation. The new SDK allows use of native modules without leaving managed workflow. Custom clients can now leverage power of Expo with flexibility of native modules.
