Zexcore is a hobby project turned into a professional, useful SDK that I am now using in almost every project. It offers analytics for applications built on the NodeJS framework, including React and ReactNative apps, backend APIs, and so on. The SDK also offers a real-time messaging SDK that lets you connect your frontend with backend using WebSockets and Redis.

With built-in functionality for Pub/Sub (using Redis), Zexcore RTM SDK can be used to build any kind of real-time apps, such as chat applications, streaming, etc.

One of my favorite use cases of Zexcore is the Cashifybot project. Aside from login/signup, the entire front end uses Zexcore RTM SDK to send/receive data from the backend API.
