Best Guide To Improve React Native Performance in 2021

Best Guide To Improve React Native Performance in 2021
29/09/2021 57

Building a react native app has significant advantages and benefits- reliability, fast, cost-cutting, and attractive UI. While working with the React Native programming language, the developers may frequently deal with issues with the performance of the programming language. The subject is that even after high maintenance and hours of coding, the programmers face great difficulties with this cross-platform app in context to performance. High-performance is a significant factor for every app development.

That is the reason there is a need to focus on the performance and execution upgrades for the React app during its development. This way, the developers can fix these issues and convey a perfect execution of the app to the end clients. There are best practices that boost up react-native performance and do not compromise with the user's experience. The language additionally makes the working patterns of the developers simple and easy, permitting them to keep a robust codebase.

React Native Performance Tips For This Situation: Do's And Don't

In any application, performance plays a significant role which can enhance the user experience drastically. React native framework offers a community-driven environment that helps in providing free components shared by experts and enthusiasts. It maximizes the savings while cutting on extra costs as its code reusability feature makes it cost-effective.

Here we have listed major do's and don't to help you improve the react-native performance. Go through the highlighted points to get into the details.


Start Using Flippers to Debug Several Issues

Flipper is a debugging platform for mobile application development that integrates the native code and native integration to inspect the component tree.

Use Image Caching Solutions

React native offers the set of components used to display images and doesn't offer solutions for issues like; flicking or rendering a lot of pictures on one screen.

Avoid Renders

React native is based on react js library. Hence we suggest you avoid unnecessary rendering and use React.memo().


Do Not Leave The Console Statements In The Code

Keeping the console statements in the source code would minimize your app performance and problems in the Javascript thread.

Do Not Go For Scrollview to Render Data

The scroll view component can be used in react native when the data you wish to render is low; however, if you have a massive list of data to render, it's a big no as giant data rendering can directly impact the performance of the mobile application.

Do Not Use Bulk Reducer

If you wish to keep up with the application performance, we will recommend you not to implement bulk reducers as it can directly impact the application performance.

Best Practises That Developers Can Follow To Improve React Native Performance

Navigation Strategies

The react native app development trends were at their peak, which let the developers work and fix the performance issue of the programming language. The team of developers has been working for a long while to resolve issues identified with navigator animations and have improved a lot of them. Yet, it should fix a few problems by offloading the main thread for most applications to execute the users consistently. When navigating the screens becomes difficult for a user, it may create a problem for your app's engagement. There are typically four methods through which can build navigation:

  • Navigator: This, however, does not work well for high-performance applications, but it can be accessed for lighter and smaller applications to work on prototype development.
  • iOS Navigator: This can be used for iOS app development and is suitable for minimal performance app development.
  • React Navigation: The react native apps are built through this navigation, generally used by every organization, and are light in weight.
  • Navigation Experiment: This can be used in complex applications. However, the complexity it has is not demanded by everyone.

Rendering Issues Settlement

A compelling reason to leverage the react-native development is to solve the rendering issue. Once the issue is resolved, we can boost the react native app performance optimization. When the user scrolls the screen rapidly, the application's User Interface crashes, and the screen is blank. This needs to be fixed by adding a text string component. Slow rendering may result in a false UI, thereby eliminating the need for users to use the app.

Using a flat list for rendering, the array elements in the list would be assumed to provide an accurate result. Giving it a priority, the developers should avoid using scroll view to render huge lists. This approach is not neglectable; it can be used when the list of items is generally small.

Removing Console Statements

Mobile app development consists of console statements that are fundamental for troubleshooting JavaScript codes, yet they are intended only for development purposes. Keeping it in the code may usually cause performance issues. Before bundling the execution, these statements need to be removed- install necessary plugins to eliminate these states from the development phase.

Adjust Image Resolutions

Adjusting image resolutions can contribute essentially to execution issues in React applications. They can likewise represent a few issues in web applications; however, the program can download and, in any event, scale the pictures. At times, it might even reserve them.

However, this is diverse with portable applications. The applications with a resize element can deal with a solitary picture quite well, yet it performs inadequately with a great deal of substantial measured pictures. The ideal approach to take care of this issue is by stacking the specific size of the image you need. All in all, you ought to resize and downsize the picture size before stacking them to your application.

Fast Loading Formats

Along with the picture size, the picture organization may likewise influence the application execution. The mobile app developers coming from the companies would lean toward JPEG and JPG designs since they consider it a significant performance issue. In any case, this isn't valid for portable stages.

Then again, you could diminish the number of distinctive pixel colours in each column of the pixels that make up a PNG picture. It could essentially reduce the picture size. It is adequate to say that the PNG design is superior to the JPG design for versatile stages.

Eliminate Unnecessary Features

One of the crucial react-native performance tips is to remove unnecessary features while developing the app. It can create page loads more slowly and minimize the usage of the application. Removing unwanted information such as data, animators, control tabs- will reduce the page load time, making the app work fast.

Every one of the unnecessary things on your application adds load times and messes up the client experience of your application, so think about diminishing applications' provisions without diminishing the UI/UX. Plan your applications to fit the plans of different devices, which will increase the app's performance.

Launch Time And Screen Orientation

In case an application's launch time is prolonged, it can hinder clients from allowing the application an opportunity in any case. One component that can influence the application's launch time is object finalize. Finalizers run on a string and can cause error messages that say your application has run out of memory when there is an adequate sum left. It can prompt more slow launching time and thereby increase the performance.

In the context of screen orientation, applications quit when the direction of the screen is changed from portrait representation to landscape. It makes gaming, taking pictures, watching recordings, and numerous different capacities troublesome. To take care of this issue, you can utilize responsive local direction. However, this element doesn't work with the iOS platform.

Use Firebase Performance Monitoring

Firebase Performance Monitoring is the assistance given by Google that assists you with acquiring experiences about the exhibition qualities of your application. It is a Google service that gains insight and revenues for mobile app development. It measures the critical capabilities of react native apps and automatically calculates the HTTP network time.

The developers utilize the Firebase SDK for react native app development to customize the execution and monitoring. The custom trace codes are being executed to increase the performance and insights of the application. The performance metrics of Firebase collect data from several processes and captures them in the app.

In the End

Boosting react native app performance is vital in each development company; however, it is likewise a complex subject to solve and make live. A few variables can influence execution, from console to animations to huge estimated pictures and weighty development calculations. Hence it is imperative to select the development company wisely to make the application stand out.

Strangely, both Android app development and iOS development give us an approach to screen memory utilization.
