React Native Mobile App : Is it Worth to use in 2022?

React Native Mobile app, a Facebook-developed open-source JavaScript-based mobile application framework, is available for download. Developers can use React with native platform capabilities to create apps for various platforms. Moreover, it is most commonly used for cross-platform Android and iOS development.

This framework entered the market as any other cross-platform programming platform. And it was criticized for being inferior to React native development. However, it became more popular over time and was praised for its ability to create valuable libraries. Major players are now exploring it.

The StackOverflow Developer Survey 2020 ranks RN 6th overall with 11.5 percent. React Native is fifth with 11.8 percent. RN is, however, still the most widely used framework, library, and tool. React Native’s popularity has increased significantly over the last five years.

What are the Native Mobile Apps?

A programming language that is specific to one operating system such as Objective C or Java for Android. The react Native offers high performance and consistency. You can also use all of the features on the phone, including the camera and address books. It can also use multiple applications without an internet connection. However, this application can be expensive to create as it is tied to one operating system. This forces the developer to make duplicates that work on different platforms.

Companies looking to market themselves on the smartphone market can use native mobile apps.

• Hybrid App: This app can be cross-platform and still allow access to the hardware of your phone. It can be created on PhoneGap and Mosync platforms.
• A dedicated web app is a website that users can use on a mobile device. These apps are only compatible with a particular platform. They will not work on any other phones, even featured phones.
• Generic Mobile App: A generic mobile app development that works with all smartphones.

In the early days of the smartphone industry, most applications were specifically designed for the iPhone. As Android’s market share grows, cross-platform capabilities have become more important.

How to Solve React Native Performance Problems:

Navigation issues:-

Since the launch of React Native, the react Native core team has had to do a lot of experimentation with navigation to get rid of inconsistencies between JS & Native Thread Bridging. React Native page browsing has some speed issues.

Time of launch:-

Slow app launch times can lead to inactive users. This is the biggest factor in user retention. React Native’s default implementations are a major cause of slow app performance and delay in app launch times. It is important to take care of the object. To speed up the app’s start time, finalize elements. Finalizers run on one thread so all objects must wait until the end. The app launches slowly because of many dependencies.

Memory leakage:-

React native app memory leaks can happen for many reasons. Scrolling in an Android music app hybrid is one example. The app slows down your phone’s performance by freezing RAM as you scroll down the music list until the third page. Both processes take place on separate pages (one in native and one in response native js), so information is transferred between them via a bridge. This can be slow.

Large app size:-

The performance of the application will be affected if it is larger. This is a common problem with Android apps. They are sensitive to third-party resources, different displays, libraries, and other factors. The application’s size will increase due to these additional resources. The large apps that have a well-defined structure are slow. Here’s how you can speed them up.

• Keep it simple, like using tools to properly package your apps.
• Make separate application files for different device architectures.
• Compress images and other graphics data-optimized bindings in your local library.

How can you improve React Native performance?

React Native apps can be made faster by following these tips.

1. Reduce the size of your application:-

To improve performance, the application’s file size can be decreased. If necessary, reduce the size of your application. The app is not working properly. Modern users have many choices for mobile apps. They won’t download your app if it is too large or takes up too much space on their devices.

Remember that the size of an application is directly proportional to its performance. To minimize the application’s size, remove unnecessary elements and reduce graphics.

2. Image reduction:-

React Native apps must implement image caching to speed uploading images. Only iPhones and iPads can use the image cache. This feature allows users to quickly access images from their smartphones.

To improve the performance of React Native, it is a good idea to reduce the image size. App performance is also improved by smaller WebP images. 25-30% can increase the iOS download speed, while 25% can increase Android’s download speed.

3. Images cache:-

Developers can improve React Native app performance by caching images. React Native supports only image caching on iOS platforms. Image caching is a way to speed up image loading. Libraries that have pre-installed images can cause an application to crash if it is upgraded. Performance suffers when we implement cache logic on JS.

4. Improve navigation:-

App functionality is dependent on navigation. To improve navigation and efficiency, it would be helpful to think about how JavaScript and native components will interact.

React Native Apps has four key navigation elements.

• Navigator: It doesn’t give you a true application life experience. It’s ideal for prototyping lightweight applications.
• Experiment with navigation: This is a great way to develop for upcoming GitHub projects.
• iOS: The Toolkit for iOS Apps
• ReactNavigation: Make the user experience smoother
• as possible.

5. Animations:-

React Native has a great animation option. It appears to be very clear and efficient. The animation library can be used by React Native programmers to allow their controllers. Animation is a way to provide a relaxing experience while executing the primary flow.

6. Improve the map:-

React Native maps can sometimes slow down when the user navigates through the application. We can fix this problem by wiping the console.log file and not exporting the data to Xcode. Developers using React Native may disable automatic location updates. The card may be made faster by decreasing the load on JavaScript threads.

Artsy has more than 1,000,000 artworks by over 100,000 artists. It is the largest online art marketplace. It allows users to bid and sell artwork from their collection.

Bitesnap:-

To count calories and nutrients, take a picture. Bitesnap will identify the ingredients in your meals. It makes it easy to develop healthy eating habits.

Bunch:-

Bunch allows users to video chat in groups while playing mobile gaming.

Coinbase Pro:-

This app is suitable for experienced crypto traders and provides them with all the tools and information they need to trade while on the move.

Crisp:-

Crisp, the first Dutch app-only grocery, delivers high-quality food direct from the source.

Delivery.com:-

Users can place orders for delivery on-demand from local restaurants or retailers through the platform. An online marketplace has over a million users and around 12,000 businesses.

Instagram:-

Instagram uses React Native to speed up its development.

Office 356 Apps:-

AppFigures says that Microsoft loves React Native and most of its Office apps is based on the React Native framework.

Future of React Native: How will it look?

React Native will continue to be a leader in React Native development services.

React Native will also be focusing on Fabric which is a large-scale, high-energy project. Fabric will help integrate the RN framework and hybrid JavaScript-based architecture. This is the goal of React Native.

Fabric’s developers propose three major changes to ReactNative that will allow it to thrive in the future. These changes are crucial.

• Fabric – A new threading model – This will allow developers to directly call into JavaScript on any thread. Instead of having each UI update execute on three threads, Fabric will allow them to do so. We can improve reliability by reducing the main thread’s load.
• React Native will now render async. This will make it easier to handle asynchronous data and allow for different rendering priorities.
• Developers plan to simplify the bridge. This will allow developers to call native JavaScript code directly from JavaScript. It will also make it easier to use many debugging tools.
