React Native Fabric: Weaving a Smoother Future for Mobile Apps

React Native has taken the mobile development world by storm, allowing developers to build cross-platform apps using JavaScript. But beneath the hood, the old rendering system was starting to show its age. Enter Fabric, the new star in the React Native tapestry, promising a smoother, faster, and more powerful future for mobile app development.

What is Fabric?

Fabric is a fundamental overhaul of React Native's rendering architecture. It moves away from the legacy system based on JavaScript bridges and embraces native C++ code. This brings several key benefits:

• Performance: Fabric boasts significant performance improvements, rendering UI changes up to twice as fast as the old system. This translates to smoother animations, quicker responses, and a more delightful user experience.
• Efficiency: Fabric eliminates unnecessary data conversions and validations, streamlining communication between JavaScript and native platforms. This means less processing power waste and less battery drain for your users.
• Unlocking the future: Fabric paves the way for exciting new features like native driverless development, custom native views, and deeper integration with platform-specific capabilities.

What is the Interop layer?

The interop layer plays a crucial role in transitioning existing React Native projects that use legacy components to the new Fabric architecture. It acts as a bridge between the old JavaScript-based components and the new Fabric system.

What about existing apps?

Don't worry, your existing React Native apps aren't left behind. Migrating to Fabric is a gradual process, and the React Native team provides comprehensive migration guides and resources. You can choose to adopt Fabric piecemeal, starting with individual components, or dive in for a complete overhaul. Existing components built with the old React Native architecture are referred to as legacy components. These components like "FastImageView", "LoaderKitView" might not be compatible with the new Fabric system directly. But by adding the below lines to the react-native.config.js we can avoid some fabric compatibility issues.

module.exports = {
    project:{
      ios: {
        unstable_reactLegacyComponentNames: []
      },
      android: {
        unstable_reactLegacyComponentNames: []
      }
   },
};        

Is Fabric the future?

While still in its early stages, Fabric shows immense promise for the future of React Native development. Its focus on performance, efficiency, and unlocking new capabilities makes it a compelling choice for building next-generation mobile apps. With Facebook already using Fabric to power its app, and a growing community of developers embracing it, the future of React Native looks brighter than ever.
