Over the last few years, React Native has escalated the mobile app development to an unprecedented level. It turned into a boon for businesses by enabling them to rationalize costs, facilitate market penetration, and develop highly responsive user experience. These advantages have been impactful enough to steer big brands like Facebook, Instagram, Walmart, Tesla, Uber, and more towards React Native app development. Furthermore, this framework has also stimulated SMEs to hire React Native app developers and yield these benefits.
Since building an app, testing it, optimizing it and launching it are the keys to creating a consistent user experience, below are some of the powerful ways to improve the performance of your app and get the most out of it.
A long feature list may cause your application to suffer slow display times. If you want your app to perform swiftly, eliminate all the unnecessary data, animations, controls, tabs, and navigations. Make sure to display the required features only as they have the potential to expand the display times of your app and result in cluttered user experience. A lean architecture will help your app fly.
If your app’s launch time is too slow, users won’t give your app a single chance. The key reason for this issue is object.finalize. Finalizers run on the main thread and can lead to error messages that show your app is running out of memory, even when there is enough RAM available. This is one of the primary reasons for the high launch times of your React Native app. To avert these issues, avoid using Object Finalizers and running essential components on the main thread.
Memory leaks have always been a critical issue in Android devices, which often happen when too many unwanted processes run in the background. In these issues, the application is closed while the memory isn’t released, and hence, in the next launch, additional memory allocates.
One of the best ways to overcome memory leakage is to use scrolling lists like SectionList, FlatList, or VirtualList, instead of ListView. These listing components will prevent memory leakage, provide smooth scrolling, and optimize the overall performance of your React Native mobile application.
Images consume a significant part of your app memory. To enhance the app performance, optimize the size of the images using services like TinyPNG before using them in the app. Besides, we recommend using webP format for JPG and PNG files to improve app loading speed up to 28% and reduce iOS and Android binary sizes by 25%.
React Native is a complex platform in terms of its architecture and different libraries, components, and Native Modules. But, ever since its inception, a plethora of organizations have trusted this framework to develop their apps as it is rewarding in many aspects. If you’re also devising to hire React Native app developers to give a mobile presence to your business, take these issues and their countermeasures into account before embarking on your cross-platform app development journey.
