In a significant shift for the React Native ecosystem, using frameworks like Expo is now the recommended way to create new React Native apps. This update marks a substantial change, aiming to simplify the development process and enhance the developer experience.

## The Evolution of React Native Development
Historically, setting up a React Native project was a cumbersome task. Developers had to juggle multiple components: setting up a JavaScript project, configuring an iOS and Android project with native tools, and integrating these elements using a somewhat obscure bundler called Metro. This complexity often led to frustration and inefficiencies.

Expo emerged as a solution to these challenges, providing a streamlined setup that alleviated much of the pain associated with traditional React Native development. For many developers, Expo became the go-to tool, significantly simplifying the process and improving productivity.

## The Shift to Frameworks
At React Conf, the official guidelines were updated to recommend using a framework like Expo for new React Native projects. This approach aligns with the broader trend in the React ecosystem, where frameworks have become essential for managing common development challenges such as code splitting, routing, and data fetching.

Frameworks like Next.js and Remix have become popular for web development, offering solutions to these recurring problems. Similarly, Expo provides a comprehensive toolbox for React Native, allowing developers to focus on building features rather than reinventing the wheel.

## Why Use a Framework?
For those deeply embedded in the Expo ecosystem, the benefits are clear. A React Native framework like Expo addresses many of the common issues faced during app development. It provides tools for navigating different screens, fetching data, managing user state, and upgrading native code between React Native versions.

Moreover, frameworks help manage dependencies and build tools, streamlining the entire development process. Xcode and Android Studio, the native development environments for iOS and Android, respectively, are known for their complexity and sluggish performance. By using a framework, much of this headache is alleviated, making development more accessible and efficient.

## The Practical Benefits of Expo
Expo offers a suite of features that enhance the development experience:

- **Easier Upgrades:** Upgrading React Native versions can be a daunting task. Expo simplifies this process, making it more manageable.
- **Developer Experience:** Expo provides a polished developer experience, reducing the time spent on setup and configuration.
- **Build Tools:** Expo’s EAS (Expo Application Services) allows developers to build iOS apps without needing a Mac, further lowering the barriers to entry.

## The Future of React Native Development
For developers already using Expo, this update confirms that they are on the right track. Those who haven't yet adopted Expo can find migration guides on the official Expo [website](https://docs.expo.dev/bare/using-expo-cli/). While it’s possible to continue using React Native without a framework, the benefits of adopting a framework like Expo are compelling.

The move towards frameworks is about more than just easing the development process; it's about enabling developers to build more robust, production-ready applications with less hassle. As the React Native ecosystem continues to evolve, frameworks like Expo will play a crucial role in shaping its future.

## Conclusion
The recommendation to use Expo for new React Native projects reflects a broader shift towards embracing frameworks that simplify and enhance the development process. By providing essential tools and addressing common challenges, Expo enables developers to focus on what matters most: creating great applications.
