In no time, React Native became a popular tool for creating apps that work on both iPhones and Android phones. Its single code base feature lets it run on multiple platforms, which saves efforts, time, and money for businesses.
But, just like any other tool, it is important to use React Native correctly to gain the most value out of it. If your app is doing everything right but not getting the desired recognition, maybe you have to check the performance optimization.
Performance Optimization Tips
These tips are mostly beneficial for app development companies. But if you are an entrepreneur from a tech background, you can also understand them and consult your React Native app development partner to check if they have worked on them or not.
Reduce Rendering And Optimize Component Updates
Take this as an example, you are drawing a picture and every time you change a tiny detail in it, you draw the whole picture again. This will take a lot of time and effort.
The same thing happens in React Native components because if you do not manage them well, they have to re-render, which makes the app slow.
To avoid this, use tools like
- React. memo
- PureComponent
- useCallback
- useMemo
Use Native Modules For Heavy Tasks And Optimize Network Requests
Sometimes, apps perform demanding tasks like playing an animation or processing lots of images at once. Although the React Native code is good for everything, you can opt for writing native code for heavy tasks like in Swift or Kotlin.
Also, use caching to save data that the user has already downloaded so the app does not have to ask for the information again and again.
Optimize Image Handling And List Views
Focusing on images, they are a big part of every app, as high resolution images may slow down the app if not optimized. For your app, use image formats like WebP, which is smaller in size but looks high quality.
You can also resize your images to the exact size of the screen shown on the app instead of going with an unnecessary resolution size. If your app has a long list of items like a feed or product list, use FlatList and Section List. They will only load currently visible items instead of loading everything at once.
Profile and Debug Performance Issues & Keep Dependencies Up-to-Date
If you still run into performance problems, it is a great idea to use profiling tools. React Native has tools that will help you to see what elements are causing performance issues or using too much memory, which you can fix. Also, keep everything up to date as they include performance improvements and bug fixes.
Partner With Experienced React Native Developers
All of these elements might sound complicated if you are an entrepreneur and not from a tech background. You do not have to do it all alone, as you can hire an experienced React Native app development services provider who will take care of the performance optimization needs.
This way you will be able to save a lot of time and headaches instead of hiring a couple of freelancers or doing it yourself.
Wrapping Up
There is no doubt that React Native is one of the most popular tools when it comes to developing cross-platform apps. But if its features and capabilities are not used wisely, the end product will run into performance issues.
The above 5 tips will help you to achieve a fast, smooth, and retaining user experience for your React Native-based app.
