Cross-platform is slowly becoming a synonym of app development. After all, businesses have started choosing hybrid apps over native apps. Why not? They are high-performing, cost-effective, easy-to-maintain, and faster to launch.
But hybrid app market was never as it is today. It is after the advent of React native cross-platform apps gained momentum. You can develop cost-effective, enterprise-level apps for Android and iOS.
That said, you may face performance issues using a React Native app. However, testing components is not always a reliable solution. Therefore, we have listed essential dos and don’ts for optimizing React Native app performance. When hiring a React Native development company in India, they must be well-versed with performance optimization techniques and tips.
- Dos for React Native app performance optimization
- Use a third-party image caching – React Native comes with an image component. It is a part of a core set of components. As the name suggests, this component allows displaying an image. But it may face issues like low performance, flickering, slow loading, and rendering of multiple images. Unfortunately, React Native does not have any solution to these problems. Therefore, it is advisable to use a third-party image caching library like react-native-fast-image.
- Optimize images – If your React Native app uses plenty of pictures, optimization is necessary. A website with more images requires rendering that leads to memory usage. As a result, your React Native app may crash. For this reason, optimize the size of website photos.
- Utilize Flipper for debugging – Flipper is a new tool released with React Native 0.62.0. It works as a debugging platform for multiple devices, such as iOS, Android, and React Native apps. With Flipper, you can debug your React Native app without the need for remote debugging. It helps you inspect crash reports, cached images, device logs, and more.
- Don’ts for React Native app performance optimization
- Never leave console statements in the source code – One of the common ways to debug React Native apps is using console.log statement. Sometimes, developers may leave console statements in the source code, which leads to extensive bottlenecks. Thus, it makes your Native React app significantly slow. You can resolve this problem using babel-plugin-transform-remove-console. It is a third-party package.
- Avoid using Scrollview for rendering data – Using Scrollview for rendering data of your React Native app is a big no-no, especially if it is massive. Scrollview is one of the components to create a scrollable list in React Native. Since it renders all children at once, it is a good option for a list of data that is quite low. If you use it for massive data, it can affect your app performance.
React Native is a cross-platform development framework that helps you build apps faster and at a reduced price. It ensures high-performing applications for both Android and iOS in 2022. But your React Native developer should consider these dos and don’ts during the development.
