When it comes to avoiding unnecessary renders on the main thread of React Native apps, there is an effective optimization technique. This library works like magic for both iOS app development and Android. Using third-party libraries like react-native-fast-image is definitely one way. However, there are still ways to deal with these issues. This component is used for displaying images, but it does not provide an out-of-the-box solution for resolving several issues, like rendering a large number of images on a single screen, cache loading performance issues, low overall app performance, image flickering, etc. Images are the core component of React Native. You may also utilize WEBP format for reducing the binary size of your images on iOS and Android by almost a third of the original size. Some best React Native app image practices include using PNG format instead of JPG format and smaller-resolution images. If not properly done, your app is likely to crash due to memory overload. Here comes the importance of optimizing images appropriately in terms of resolution and size. When you render multiple images in your React Native app, it may lead to high memory usage on a device. Make sure you focus on optimizing images, including graphical content, when improving the performance of your React Native app. In this way, you can remove any possibility of removing references across re-renders. Best practices recommend you declare the function as a class method or as a function inside a functional component. Simply put, the child component re-renders even when the props did not change at all. At times when the parent re-renders a new reference, which creates another function. When it comes to passing a function as a property to a component, it is better to avoid passing that function inline. To fix this issue, experts recommend listing the items with FlatList. This is especially true when there are a large number of items in the list. Displaying a scrollable list by using ScrollView is simple, but on the other hand, it can directly affect the overall performance of the React Native app. When it comes to displaying items in React Native with scrollable lists, there are two ways to do it using ScrollView and FlatList components. Avoid Using Scroll View to Render Huge Lists iOS Navigator is only used for iOS navigation development and can only be used to fix navigation issues with small applications and prototype development. React Navigation is preferred by developers for a wide number of apps regardless of size. Fortunately, there are a number of solutions to these problems, including React Navigation, iOS Navigator, Navigator and Navigation Experiment. However, you may run into some problems that you still need to resolve on your own. Thanks to an active and large React Native developer community, many navigational problems have already been resolved. ![]() Navigation issues occasionally prevent apps from giving users a flawless experience. There are occasions when developers have trouble navigating React Native apps. Let’s take a dive deep into some of the best practices for effectively improving the performance of a React Native app. Tips for Improving Performance in a React Native App In this blog, we will discuss some best practices for improving the performance of React Native apps. Therefore, it’s important to pay attention to best practices and performance enhancements for your React Native app while it’s being developed. Or, you can learn and implement best practices on your own.Įven though React Native is one of the top app development technologies, performance issues with your app may arise occasionally. You may opt for professional React Native Development Services for improving the performance of your app. But, there are occasions when you may feel the need to optimize your app. React Native tries to provide everything that is needed to develop a high performing application. After all, in the age of the Internet, every business needs a high-performing app that squarely satisfies customer needs. No wonder so many successful companies rely on React Native for building their applications. It offers scalability, flexibility, speed, agility, cost-efficiency and excellent performance. There is no denying the fact that React Native is the future of developing hybrid apps.
