React Native 0.75

Introduction:

React Native is one of the most popular frameworks for building mobile apps using a single codebase. With each new release, it gets more stable, powerful, and performance-oriented. React Native 0.75 is no different—it brings meaningful updates aimed at improving developer experience, performance, and compatibility with the latest mobile platforms.

In this article, we will explore what’s new in React Native 0.75, how it impacts developers, and why it’s a good time to consider upgrading your apps.

What is React Native?

Before diving into React native version 0.75, let’s quickly recap what React Native is.

React Native is an open-source mobile app development framework created by Meta (formerly Facebook). It allows developers to build cross-platform apps for iOS and Android using JavaScript and React. Instead of writing two separate codebases, developers can build apps faster while maintaining native-like performance.

Why Version Updates Matter

Each React Native version comes with enhancements like:

  • Bug fixes
  • New features
  • Improved performance
  • Updated dependencies
  • Better support for native modules and APIs

Staying up to date means your apps remain stable, compatible, and secure.

What’s New in React Native 0.75?

Here are the major highlights of React Native 0.75:

  1. Full Support for Fabric and TurboModules

React Native 0.75 continues to strengthen the foundation laid by Fabric and TurboModules. Fabric is the new rendering engine, while TurboModules improve how JavaScript talks to native code.

What this means:

  • Better UI performance
  • Reduced lag and smoother animations
  • Faster communication between JS and native modules
  • More responsive and fluid apps

Fabric and TurboModules are now more stable and enabled by default, bringing React Native closer to native-level performance.

  1. Upgraded Hermes Engine

Hermes, the JavaScript engine optimized for React Native, gets a major update in version 0.75. The new version is faster, lighter, and more memory-efficient.

Benefits of Hermes in 0.75:

  • Faster app startup times
  • Smaller bundle size
  • Reduced memory usage
  • Better performance on low-end devices

If you’re not using Hermes yet, this is the perfect time to enable it in your project.

  1. Improved Metro Bundler

Metro, the JavaScript bundler used in React Native, has been enhanced in this release. It now offers better caching, faster rebuild times, and fewer issues with large codebases.

Developer benefit:

  • Faster builds and reloads during development
  • More efficient production bundles
  • Easier debugging with clearer error messages
  1. Updated Dependencies and Platform Support

React Native 0.75 updates several core dependencies to align with the latest versions of iOS and Android SDKs. This ensures better compatibility with new devices and system features.

Key updates include:

  • Support for Android API Level 34
  • Improved iOS 17 compatibility
  • Updated React to 18.2
  • Modernized Gradle and CocoaPods support

Staying up to date with these ensures your app works smoothly on new devices and app store guidelines.

  1. New Dev Tools and Debugging Improvements

React Native 0.75 introduces improvements to developer tooling. This includes better error messages, warnings, and debugging support for modern tools.

Notable improvements:

  • Enhanced support for Flipper (debugging tool)
  • Improved source maps for easier bug tracking
  • Clearer stack traces and console output

These updates help developers find and fix issues faster, boosting productivity.

How to Upgrade to React Native 0.75

Upgrading is easier than ever using the React Native Upgrade Helper: https://react-native-community.github.io/upgrade-helper

Steps to upgrade:

  1. Backup your project.

  2. Follow the diff on the Upgrade Helper for 0.75.

  3. Run:

				
					npx react-native upgrade

				
			

Test thoroughly and fix any breaking changes.

Should You Upgrade?

Yes, especially if:

  • You want better performance with Fabric and Hermes.
  • You’re building for the latest versions of iOS and Android.
  • You want smoother development with improved bundling and tooling.

If you’re starting a new project, starting with React Native 0.75 is a no-brainer. If you already have an app, consider upgrading during your next development cycle to avoid technical debt.

Real-World Use Cases

Here’s how React Native 0.75 can help in real projects:

  1. Faster Time to Market

Thanks to improved bundling and better support for native modules, you can deliver features faster without sacrificing performance.

  1. Better User Experience

With Fabric and TurboModules, UIs are smoother, animations are less laggy, and load times are shorter—key factors in user satisfaction.

  1. Lower Development Costs

By hiring a single team to write shared code using React Native, businesses can cut costs compared to maintaining separate iOS and Android teams. You can even choose to hire React Native developers remotely or from agencies that specialize in cross-platform development.

Conclusion

React Native 0.75 brings the framework another step closer to native app performance, while keeping the speed and flexibility developers love. With updates to Hermes, Fabric, Metro, and dependency alignment, this release is built for the future.

If you’re looking to build high-performing, cost-effective mobile apps in 2025 and beyond, React Native 0.75 is your go-to choice. Whether you’re upgrading or starting fresh, the improvements in this version make it easier than ever to deliver modern, scalable apps. To get the most out of these new features, it’s a smart move to hire React Native developers who are experienced with the latest version and can build fast, reliable, and user-friendly apps.
