React Native has become a popular and best choice for mobile application developers. Thanks to this technology, developers may create apps that function on several platforms. And along with this, it also provides higher performance and a native-like feel. Hence, it is very crucial to optimize your React Native application. It will guarantee that you can provide a smoother and more improved user experience.
In this content, we will dive deep into React Native App Development Services and optimize the performance of your apps.
Why is your React Native app slow?
The performance of an application is impacted when you do one task
repeatedly. It might also get affected when the components get too heavy and
must be rendered often. Here are some of the most common reasons that react
native app ios or react native app android is slow:
●
Think of a
scenario where you change the variable and need to re-render the app.Yes, it
may cause your app to operate worse. Hence it enhances the need for frame rates
that retards the speed.
●
Also, it
might be that caching components many times can add to the app's memory. Hence,
this can also impact the performance.
●
You must
use pure components for all the static elements in your application. And if
not, then it can hamper speed.
●
If you are
loading a massive amount of data or uploading significant components, it can
hamper the speed of the page.
●
At last,
when you want to seek a particular page, it can increase loading time and
hamper performance.
Are you worried about React native mobile app performance? Let's see how to optimize it.
Top Ways To Optimize Your React Native App Performance
1) Identify the Root Cause of Performance Issues
The very first step you will have to take care of while you optimize your React Native app is to analyze the main reason behind the issues of the performance. I know why you are experiencing this. There are plenty of tools available to help you with it. Hence, you can employ tools like React Native Debugger. It will let you debug and profile the app.
Ultimately, when you know the reason behind performance issues, you can quickly start working on its improvement.
2) Use FlatList Instead of ScrollView
React Native has a ScrollView element that helps represent lower data. But it might come sluggish when you want to express massive quantities of data. Hence, if you want to optimize the app, using the FlatList element is better than others. This element is made for a better picture of a massive list of data. It can give you good features like horizonless scrolling and data paging.
3) Optimize Your Images
Are you aware that one of the key components of a mobile application is an image? Therefore, if you are experiencing anxiety regarding the performance, this may be the primary cause. Hence make sure that you optimize the React Native app to overcome all the problems in speed. For optimizing this you can make sure that the size of the image is good. Know that displayed images are crucial.
For this, using tools such as ImageResizer and react-native-fast-image is better. Hence, it will help you optimize images for better results. Hire React Native Developers that can optimize these images.
4) Use Pure Components
Although React Native offers a number of methods for optimizing the picture of factors, using pure constituents is one of the best approaches.
Pure factors can drastically lower the amount of work required to induce your application because they only render when their props or state change.
5) Minimize Re-renders
One of the most common issues that hamper React Native app performance is Re-rendering. Hence, it's essential to reduce re-renders to avoid streamlining the app's state.
A way to do so is to use useCallback and useMemo hooks. Hence, this will help you flash back your functions and values. Hence, it can help you exclude all the gratuitous re-renders by only streamlining it when necessary.
6) Use Native Modules
React Native is known to let you use native modules that can help enhance
performance. For instance, one can use modules that provide access to
functionalities just like an accelerometer.
Hence, these modules can enhance the other app's performance, lessening the work amount for performing tasks.
7) Use the VirtualizedList Component
If you want to render massive data in the basic React native app, you can try the VirtualizedList component rather than the FlatList component.
Hence, this VirtualizedList component is made for rendering a massive list of data just by generating the items. Later, these things are currently not available on screen.
8) Use RequestAnimationFrame
One of the functions of JavaScript is RequestAnimationFrame. One can use it to optimize the animations in the React native app iOS. Hence, this ensures that animations move smoothly and don't result in jank or stuttering.
9) Optimize Your Code
In the end, it is crucial to optimize your application's code to ensure
that it runs as effectively as possible. Hence, this might include code
splitting, lazy loading, and tree shaking.
Code splitting is a method that can help cut down code into manageable and small parts. Additionally, lazy loading can help load app features whenever you need them. I suggest using tree shaking can remove unnecessary code from applications.
Conclusion
The tips that you read above are surely going to help you as per us. Hence carefully go through all of the tips mentioned above. It can help you in maximizing the functionality along with great performance. For better performance first you will have to know the cause and then improve it. Doing this will help your app run like smooth butter.
It is a very smart move to adopt certain tools and React native app builders for these tasks. Enhancing the performance app will compel users to come on your website more. Hence these strategies above will help you React Native app that people will love.
