It’s worth noting that the framework continues to be actively maintained and developed, adapting to the evolving needs of app developers. As long as you consider React Native app development for your next project, let’s check how this technology works at its core.


With the new architecture rolled out in 2022, it’s essential to understand how the framework works and how it might affect React Native app development. Before we proceed with the new architecture description, let’s take a look at the previous one.

During the execution of a React Native app, the JavaScript code is bundled into a package called the JS Bundle, while the Native Code remains separate. The execution of React Native apps involves three threads. 

  • The JS Engine utilizes the JavaScript thread to run the JS Bundle. 
  • The Native/UI thread is responsible for running the Native Modules and managing tasks such as UI rendering and user gesture events. 
  • The third one, called the shadow thread, calculates the layout of elements prior to rendering them on the host screen.

Communication between the JS and Native Threads occurs through a component known as the bridge. When data is transmitted through the bridge, it needs to be optimized and serialized as JSON. It’s important to note that this bridge only supports asynchronous communication.

The introduction of the React Native 0.68 version brought about a new architecture, incorporating two significant components: the Fabric Renderer, which is a new rendering system, and TurboModules, a fresh native modules system. These modules greatly enhance the communication between native code and JavaScript. Furthermore, a new renderer implemented in C++ and a shared core among platforms have been included, facilitating the adoption of React Native on different platforms.

Beginning from React Native 0.70, the default engine is now Hermes, resulting in faster app startup time and a smaller APK file size for Android. Although the IPA file size for iOS may have slightly increased, there is a reduction in memory consumption.

In the new architecture, the concept of the bridge has been replaced by a different communication mechanism known as the JavaScript Interface (JSI). The JSI serves as an interface that enables a JavaScript object to maintain a reference to a C++ object and vice versa.

In essence, these updates enhance the efficiency of your application. With faster loading times and reduced memory consumption, you can expect improved user engagement and satisfaction over time. Besides, it introduced such distinct benefits as synchronous execution, concurrency, lower overhead, code sharing, type safety, etc.
