In React Native 0.80, we're introducing two significant changes to React Native's JavaScript API — the deprecation of deep imports, and our new Strict TypeScript API. These are part of an ongoing effort to accurately define our API and offer dependable type safety to users and frameworks.

The React Native Blog offers insights, updates, and tutorials on React Native development, a popular framework for building cross-platform mobile applications using JavaScript and React. Developers can learn about React Native best practices, new features, and community announcements, as well as discover tips for optimizing performance and debugging mobile apps. Additionally, the blog covers topics such as navigation, state management, and integrating native modules, providing resources for mobile app developers.

React Native 0.80 introduces two major API changes: deprecation of deep imports from the react-native package and an opt-in Strict TypeScript API. Deep imports will show warnings and be removed in version 0.82, requiring developers to use root imports instead. The new Strict TypeScript API generates types directly from source code, providing better accuracy and type safety. Developers can opt in via tsconfig.json configuration, though some breaking changes in type names and shapes are expected. These changes aim to stabilize React Native's JavaScript API for future releases.
