Unlock the Power of React Native 0.64
The wait is finally over! After months of anticipation, React Native 0.64 has arrived, bringing with it a slew of exciting new features that will revolutionize the way developers build mobile apps.
Hermes Takes Center Stage on iOS
Hermes, the open-source JavaScript engine, has finally made its way to iOS, marking a significant milestone in the evolution of React Native. This lightweight solution tackles the common issues of large bundle size, excessive phone memory usage, and increased interaction time, resulting in a seamless user experience.
What Does Hermes Mean for iOS Developers?
With Hermes, iOS developers can now enjoy improved app performance, reduced memory utilization, and faster interaction times. This game-changing technology is poised to take the React Native community by storm, encouraging developers to contribute to its growth and development.
Getting Started with Hermes on iOS
To harness the power of Hermes on iOS, simply upgrade your project to React Native 0.64, set hermes_enabled to true in your podfile, and run pod install. Note that Hermes support on iOS is still in its early stages, with further improvements and support expected in the coming days.
Unleash the Power of Hermes Tracing
Facebook’s collaboration with Major League Hacking has led to the development of a feature that allows developers to visualize Hermes tracing profiles using Chrome DevTools. This powerful tool enables you to optimize your app’s performance like never before.
Hermes Gains Proxy Support
React Native 0.64 also introduces proxy support for Hermes, ensuring compatibility with popular community projects like React Native Firebase and MobX. If you’re already using these packages, you can now seamlessly migrate your project to Hermes.
Inline Requires: The Key to Faster App Startup
Inline requires, a Metro configuration option, is now enabled by default in React Native 0.64. This feature accelerates app startup by delaying the execution of JavaScript modules until they’re needed, resulting in faster-performing mobile apps without any extra configuration.
What’s New in React 17?
React 17 may not bring any revolutionary new features, but it’s an essential “stepping stone” release that paves the way for future innovations. This update makes it safer to embed React trees inside other frameworks and eliminates the need to import React to use JSX.
Dependency Changes: What You Need to Know
React Native 0.64 comes with several key dependency changes, including:
- Dropped support for Android API levels 16–20
- Required Xcode 12 and CocoaPods 1.10
- Minimum Node.js support bumped to version 12
- Flipper updated to 0.75.1
