What is Fabric in React Native?

Fabric is the new modernized architecture introduced by React Native to enhance application functionality and make it run faster. It is specifically designed to overcome the challenges of the older system. Moreover, React Native fabric aims to re-render the layer system and make it future-proof and responsive.

Additionally, the fabric architecture of React Native’s core principles unifies more render logic in C++ and unleashes new abilities of React Native development. It also introduced the new render and its concepts. The fabric React Native does not include the platform specification, code snippets, and pointers.

Features of React Native Fabric

The fabric in React Native is here to transform your app faster and more upgraded. Following are its core features, which will help you to re-render the new system and enhance the overall developer experience.

1. JavaScript Interface (JSI)
This feature enables you to communicate with native code. In the earlier version, React Native was handled differently. Now, the JavaScript Interface (JSI) has replaced the bridge, allowing you to communicate directly, decreasing latency, and improving app performance.

Moreover, JSI enhances the efficiency and speed of operations, such as with device cameras, sensors, or GPS. It allows your developer more flexibility to integrate third-party and native modules seamlessly.

2. Concurrent Mode
The concurrent system is one of the robust features of React Native fabric. It optimizes the rendering process to ensure that the app remains responsive, manages complex UI updates, and handles multiple tasks simultaneously.

With this concurrent mode, you can highlight user interactions such as scrolling, clicks, and buttons. Moreover, by breaking the render tasks into smaller chunks, the system will eliminate the blocking operations that cause your app to lag or become unresponsive. This is quite beneficial for apps with complex UI interactions and performance.

3. Asynchronous Rendering
Asynchronous rendering works well with concurrent mode to break down rendering tasks into smaller units that can efficiently execute differently. It ensures that UI is updated in a non-blocking way and makes the app rapid and responsive. It also indicates that it can respond to user input while processing heavy updates and background tasks.

Moreover, it allows your system to run in the background without affecting UI responsiveness. For instance, an app with a product image or video can quickly be loaded into the environment. Also, reduce the UI of unnecessary complex tasks.

4. TurboModule System
This feature stands out for optimizing React Native modules. The TurboModules system addresses memory usage and enables on-demand loading of native modules whenever required. Moreover, it improves the interaction between Native code and JavaScript using JSI.

As a result, it loads the app faster and more efficiently without depending on several native modules. For instance, an app might include numerous native modules like camera and Bluetooth access, but turbo modules ensure that the loading time and memory consumption are decreased.

5. Custom Native Components
With React Native fabric flexibility, you can create custom native components. These components can directly integrate into your React Native app and offer control over how native views and functions are rendered. They also allow you to develop highly customized performance views for React Native apps.

The React Native fabric architecture efficiently bridges the gap between native platforms and JavaScript. It also helps manage a consistent and responsive user experience across Android and iOS. The custom native components features are advantageous for creating advanced UI elements or functionalities.

A Technical Overview of React Native Fabric Pipeline

Fabric render is part of React Native’s modern architecture, which provides enhanced performance, extensibility, and consistency. It has three phases: The rendering phase, the commit phase, and the mount phase.

1. The Rendering Phase
It is the first stage in which you can create a React element tree and convert it into a more efficient React shadow tree. In the render phase, React executes product logic into element trees. The React Element is the plain JavaScript object that defines what should appear on the app screen.

The react element tree is used to render the react shadow tree in C++. The react shadow tree created by the fabric renderer consists of react shadow nodes, representing the react host components to be mounted and containing props that originate from Javascript.

Each React element is summoned in the Render phase, and the renderer synchronously creates a React shadow node.

Note: The above code would glimpse the summarized into a ViewShadowNode object when translated into a React Shadow Block.

2. The Commit Phase
The Yoga layout cross-platform layout engine is significant for handling tree and layout calculation operations. It occurred in the commit phase, where operations handling is essential.

Moreover, the layout calculation calculates the positions and sizes of each React shadow node, such as where and how it should be. As the Yoga engine summons, it helps to calculate the layout of each React shadow node element.

And once it is calculated, the Tree promotion operation promotes the new React shadow tree as the next one to be mounted. This promotion also conveys the latest state of the React element tree.

3. The Mount Phase
The final phase involves the native views mounting to the screen, making the user interface more visible. In this phase, the React shadow tree (data to calculate layout) is shifted into a host view tree by rendering pixels on the screen.

The mounting phase ensures that each component is correctly positioned and styled according to the React Element Tree’s defined layout. It has been updated in the pipeline and includes three steps: tree diffing, tree promotions, and view mounting.

What are the Benefits of Fabric React Native?

The new Fabric in React Native offers developers several advantages, such as eliminating errors and saving effort, instead of using the traditional communication render method. Here’s how React Native fabric makes it better into your app-

1. Interoperability Host Platform
One significant benefit of React Native Fabric is that it improves interoperability with host platforms like Android and iOS. The fabric assists in eliminating the bottlenecks associated with the older bridge architecture. It also enables you to more efficiently access platform-specific features like geolocation or camera. Another benefit is that it maintains the React Native codebase.

The enhanced interoperability makes it easier to build apps that maximize the full potential of native device abilities. Moreover, it simplifies the integration process with third-party native libraries and direct communication among modules.

2. Enhance Performance
React Native has introduced Fabric, keeping improved performance as its core significance. It is designed to deliver enhancement and replace the traditional bridge model using JSI. With the improved performance, it reduces the latency between Native code and JavaScript.

Additionally, the fabric renderer React Native includes asynchronous rendering and concurrent mode, which ensure prioritized tasks and smooth the UI process. The optimized architecture allows your app to manage complex animations and data processing without any lag.

3. Type Safety
Fabric in React Native provides better type safety for error-free and robust code. The React Native fabric performance utilizes a modern type system to decrease the runtime error and testing overhead. Type safety enhances the reliability of the app and speeds up development.

It is ideal for large and complex applications where you do not have to worry about the type mismatch lead crashes or subtle bugs. As a result, it corrects unexpected data types and catches error issues during the early development process. Moreover, type safety utilizes JS components to generate C++ structure.

4. Rapid Startup Time
React Native enables Fabric to contain host components, which are lazy initialized by default. It improves app startup times by implementing the TurboModules system into the applications, which loads the necessary native modules. It ensures rapid runtime with operating required modules and can function during many dependencies or large codebases.

Rapid startup time also improves the user experience and makes the app more responsive right from the beginning. It is crucial for apps with heavy functionality and allows you to create apps with quick runtime.

5. C++ Compatibility
React Native fabric architecture is built with C++ compatibility, making your app highly flexible and modular. It allows your developer to write custom native components and integrate them with low-level libraries. With C++ and Fabric, you can optimize the communication layer between the modules.

The React Native fabric and C++ compatibility enable you to develop performance-driven feature apps, including complex data, custom animations, and modern graphics rendering. It also allows you to share among different platforms, increasing consistency and adopting React Native on new platforms with C++ core.

6. Cross-Platform Consistency
The fabric React Native emphasizes cross-platform consistency and ensures that renders act the same way on iOS and Android. It also eliminates the requirement of writing native code twice, which results in fewer bugs and more time addressing critical issues.
