Expo Hot Reloading
Expo Hot Reloading is a development feature in the Expo framework that automatically reloads a React Native app in real-time when code changes are detected, without requiring a full app restart. It preserves the app's state, such as navigation and form inputs, allowing developers to see immediate feedback on their modifications. This tool is integrated into the Expo CLI and works with the Expo Go app or development builds to streamline the React Native development workflow.
Developers should use Expo Hot Reloading when building React Native apps with Expo to accelerate development by reducing the time spent on manual reloads and debugging. It is particularly useful during UI development, styling adjustments, and iterative testing, as it provides instant visual feedback without losing app state. This enhances productivity in scenarios like prototyping, feature implementation, and bug fixes in React Native projects.
