Guide to Scalable IoT App Design with React Native

This blog looks at IoT app development with React Native that can handle more users and data over time. It starts by explaining how React Native bridges mobile and device communication layers, supports remote sensors, and manages live data streams.

You'll see examples of using efficient state management (like Redux or Context API), background tasks, and WebSockets for real-time updates. The blog also notes best practices for code structure, API handling, and device pairing to keep the app reliable as it grows.
