How to Improve Performance of React Native Application?
React Native App Development Services propounds an optimistic solution for the clients looking out for a feasible framework on which to design and develop cross-platform applications. For this fact, some of the world’s largest organizations are making the switch to React Native and proposing to Hire React Native Developers. To reach the absolute accomplishment potential of your React Native app after everything, optimization is a significant step. Let’s take a look at some of the foremost practices for improving the overall performance of a React Native application and making the app work twice as fast and way more efficiently.
l Cache the images locally-
Reactive Native issues an image as a core component that enables developers to exhibit images. Nevertheless, there are a few problems with this image component. To solve these problems, you can cache the image and take the help of the local cache in the successive application. However, React Native presently supports incorporated caching only in iOS and not in Android. These performance issues can efficiently be bent-on acquiring a third-party library called react-native-image. The fast image enables consumers to proffer images rapidly using a cache implementation. Additionally, it also appends authorization headers and several other advanced features.
l Withdraw all console statements–
l Remove needless libraries & features-
Each library in a React Native application imparts some impression on the application. It is the reason why you should only add the libraries and functionalities you require in your app and withdraw all the trivial dependencies and libraries. Different animations, navigations, tabs, and other functions can hand out to the screen load time and so the more overstuffed your screen is, the worse it will perform.
l Utilize useMemo–
You can acquire useMemo hooks to steer clear of re-rendering, and it helps to avoid re-rendering of minor components by remitting memorized values of a function. If by chance any component acquires the same props more than once, useMemo, thereby, will take help of formerly cached props and render the JSX view and directly return the component. Hence, useMemo majorly helps to enhance the performance of RN applications. To be noted, it should be taken into consideration only when performing expensive computations, as we can memorize the calculations to recalculate the outcomes if only the values are in variation.
l Optimization of code-
Good coding exercises and approaches can aid in making your applications one step ahead. Consequently, for better practice, you should prevent unessential render calls and unspecified functions. These numerous render calls can lead to serious performance issues. You can also use PureComponent to operate them without handling them manually. This component does not alter props or the state inside the component, averting multiple render calls.
Several factors influence the performance of a React Native app, such as having large images, heavy calculations, and inessential render calls. On the bright side, one should avoid some common performance issues by ensuing best approaches and using tools considered and suggested in this article.
