What Is React Native?

React Native is an open-source framework developed by Facebook for creating native apps for iOS and Android using a single JavaScript codebase. It enables developers to build mobile applications that are indistinguishable from an app built using Objective-C, Swift, or Java.

Why Migrate to React Native?

The question isn’t why should you, but rather why haven’t you yet? Migrating to React Native means:

  • Reduced Development Time: The “write once, run everywhere” approach ensures compatibility and efficiency across different platforms.
  • Enhanced Performance: React Native compiles directly into native app components, enabling it to achieve the same level of performance as a native application.
  • Hot Reloading: Experience the convenience of viewing changes in real-time, eliminating the need to restart your app.
  • Expansive Community & Ecosystem: Enjoy access to an extensive collection of libraries, UI kits, and tools that empower development and design.
  • Cost Efficiency: Efficiently share code across different platforms, significantly reducing the necessity for having separate development teams for iOS and Android, thereby streamlining the development process.
  • Live Updates: Deploy updates directly to users bypassing the time-consuming app store approval process, ensuring immediate availability of new features and bug fixes.

Common FAQs About Migrating to React Native

Let’s look at React Native Development FAQs related to Migrating to React Native.

1. How does React Native differ from other frameworks like Cordova or Xamarin?

React Native uses a different approach to bridge the gap between web and mobile. Unlike Cordova, which renders through WebView, or Xamarin, which uses C#, React Native allows you to write real, natively rendering mobile applications for both iOS and Android in JavaScript.

2. Can existing components written in a native language be used in React Native?

Absolutely! React Native’s architecture is modular, which means you can integrate it with components written in Swift, Objective-C, or Java. It’s perfect for a gradual migration.

3. What about app performance? Is React Native slower than native apps?

No, React Native performs almost on par with native apps because it compiles to native code. However, complex animations and transitions may require more work to maintain smoothness, akin to native app standards.

4. Is it possible to migrate a large, complex app to React Native?

Yes, it actually can be even more beneficial for such applications. You can migrate in parts, allowing your team to refactor and scale the app effectively.

5. How do we manage state in a large React Native application?

The answer lies within modern state management libraries like Redux, MobX, or the Context API that come with React. Choose based on your project needs and complexity.

6. Are there any design limitations when switching to React Native?

While React Native provides a lot of flexibility, it also requires you to rethink design layouts as it uses Flexbox for positioning. However, this often translates to a more consistent UI/UX across devices.

7. What should be the first step when considering migration to React Native?

Start by evaluating your current app’s architecture, dependencies, and business logic. Then, plan a gradual migration of components to React Native while keeping the existing codebase functional.

8. How does React Native handle security concerns?

React Native follows the same security principles as a traditional native app. It’s imperative to use secure communication channels (like HTTPS), secure storage mechanisms, and proper API authentication.

9. Can React Native handle deep linking?

Yes, with its built-in linking library, React Native simplifies both deep linking and navigation among different screens inside the app.

10. Will we need to learn new programming languages to use React Native?

If you already know JavaScript, you’re ready to jump in! For certain native modules or custom plugins, familiarity with Swift, Objective-C, or Java could be beneficial.


Migrating to React Native is a strategic move that can bring efficiency, performance, and cost-savings to your development process. Hopefully, this FAQ has shone a light on the path ahead.

Remember, the key to a successful migration lies in thorough planning, patience, and an eagerness to engage with the thriving React Native community. Bon Voyage on your journey to the world of React Native!
