Build web apps that scale across platforms

This article explains how the Super App Showcase structures a React Native super app around a Host Shell, federated mini apps, and a Shared SDK. It covers how Re.Pack and Module Federation load feature bundles at runtime while the host keeps native code and shared singletons consistent. The cold-start sequence shows how these parts work together, while the sections that follow cover module setup, shared state, real-time data, and UI performance. The final section focuses on production requirements for remote bundle discovery and version compatibility.
