Undoubtedly, React Native is the future of hybrid app development. The way people are opting for this technology, it is not hard to believe that all apps will be developed on React Native in the coming years.
And why not? Will it be true? React Native gives us all reasons to use it for Hire App Developer. From scalability to flexibility and speedier development to cost-efficiency, this technology excels at every level of mobile app development.
Now, developing an app on React Native is easier than ever, as the top React Native app development company helps you build your dream app.
But the most important thing that we must notice is the app performance of a React Native app. So, how to boost the performance of a React Native app?
Well, there is nothing complicated in enhancing your app performance. React Native professionals are there to assist you in boosting the app’s performance. But before contacting them, you must know the best practices to enhance app performance. Therefore, this post is a must to read to get all the required information. So, don’t miss out on anything, and start reading!
Best Practices for Improving Performance in a React Native App
Navigation Strategies
It has been observed that apps developed on React Natives show some navigation problems. However, these issues can be fixed with appropriate navigation strategies. Given are the four different navigators that you can use in React Native:
Navigator: It is best to use for small applications and prototype development. However, it won’t work fine for complex or high-performance applications.
iOS Navigator: This navigator is used only for iOS and doesn’t work with Android navigation development.
React Navigation: Many apps often recommend this navigator for app development. Also, it is lightweight and accessible for both small- and large-scale apps.
Navigation Experiment: For any complex application, it is the optimum option. But due to the implementation complexity, not everyone prefers it.
Scroll View to Render Huge Lists
There are two ways to use the ScrollView and FlatList components in React Native to display items in scrollable lists. Although using ScrollView to display a scrollable list is straightforward, the speed of the React Native app as a whole may be negatively impacted. This is particularly true if the list has a lot of entries. In addition, experts advise using FlatList to list the items to resolve this problem. So, avoid using scroll view to render a huge list to improve React Native app performance.
Resizing & Scaling Images
When optimizing the performance of your React Native app, make sure to prioritize image optimization, including graphical content. When you render multiple images in your React Native application, your device’s memory usage may increase. Here comes the significance of appropriately optimizing images in terms of resolution and size. If not done correctly, your app will most likely crash due to memory overload. Using PNG format instead of JPG format and smaller-resolution images are two of the best React Native app image practices.
Moreover, the WEBP format reduces the binary size of your images on iOS and Android. And it reduces nearly a third of the original size of the image. Thus, resizing and scaling images is essential to optimize the app’s performance. Always discuss it with the app development company that handles your project to do so.
Use Hermes
Hermes is a free and open-source JavaScript engine designed primarily for mobile applications. Hermes’ primary function is to reduce the APK download size, memory footprint, and consumption, as well as the time required for the app to become interactive. Choosing a professional React Native app development company will enable Hermes for iOS and Android.
Cache Images
Among other practices, caching images is another aspect to consider. React Native provides a core component. And this component plays a role in displaying an image, but it doesn’t have an extraordinary solution for problems such as:
- Low performance in general
- Image flickering
- Low performance in cache loading
- Rendering a vast number of images on a single screen
Conclusion
Though the list of best practices to optimize React Native app performance is never-ending. Depending upon the challenges, one should choose how to eliminate them. The tips mentioned above will surely help you to enhance your app’s performance. However, you must communicate with a top mobile app development company to improve performance. An experienced app development company can provide high-end performing applications that meet your business needs.
