Steps to Optimizing the Performance of the React Native Applications

Leave a Comment / Uncategorized /

React Native developed by Facebook has indeed become one of the most preferred JavaScript library code frameworks for creating cross-platform applications. Although the initial launch was just five years ago in 2013 on GitHub but it has created more buzz in comparison to Xamarin and Ionic. The one aspect that literally goes into the favor of the React Native is that it allows the developers to develop mobile and web applications at a much faster pace. Moreover, you can build both the Android and iOS apps by sharing and reusing the codes easily. Another advantage that React Native offers is that there is not much of a difference between completed apps created using Objective-C or Java and React Native. React Native also enjoys the support of a great network of experienced developers. However, it also has a few drawbacks as well. One of the major pitfalls of React Native is that it has got its limitations and as such it is still on the way to improvement. You won’t find some of the custom modules, which means you have to invest some more time to create your own module. Therefore, we would be readily discussing some of the vital ways using which you can improve the performance of your React Native apps. Before we can shed some light on how to fix the performance based issues related to React Native, you need to understand well that the performance of this JavaScript library depends on the architecture to much extent. The increase in the number of navigation controls, the animation and tabs slows down the speed of the user interface in the application. In addition, during the upgrading the application, the version tends to get changed and it can also become a key bottleneck in the application’s performance. The React Native basically communicates with native thread with the help of a bridge. And the architecture of the React Native can be categorized into two categories namely; the React Native developed on Java, Swift or Objective-C and the native created on JavaScript. So, we can focus on these vital parameters to improve the performance. Reducing the Size of the Application The JavaScript framework apps depend largely on the native components and third-party libraries. The more use of the components enhance the size of the application. Therefore, if you have to reduce the size of the application, you have to use ProGuard and also develop apps of variant sizes for an array of device architecture. In addition, please do focus also on the graphic elements and images. You can also take some other steps to curtail the size such as shifting the components from native to react native, reduce the size of the bridge that JavaScript uses to interact with native. You can also go through the open-source libraries to check its stability before using it. Do not use the main thread to pass the components relying on heavy message queues. Reducing the Size of the Image If you want to optimize the performance of your React Native applications, you also need to necessarily reduce the size of the image apart from lowering the size of the application. You should note that the images tend to consume a large part of the memory. There are many ways to achieve your ends. The first is using the smaller size photos. Secondly, you should give preference to the PNG file format for image uploading in comparison to the widely-used JPG or JPEG format. However, it would be best to convert your image version to WebP format. This is because WebP offers a number of benefits such as increasing the loading speed up to 28% and reducing the binary sizes of iOS and Android by 25%. Apart from that, it also cuts down the CodePush bundle by 66% and makes the transition of the navigator smooth. Image Caching The image caching is regarded as an important step when you are planning to improve the performance of React Native applications. It helps in swifter loading of the images. However, the React Native supports the image caching only for the iOS platform. As far as the Android OS is concerned, you get the assistance of the npm libraries for the image caching, but they do not offer optimum performance. Besides you can also face a few other issues such as failure of libraries for not being able to bring the preloaded images when the page of the app gets refreshed. This is known as cache miss. Another problem that might prop up is performance draining when the cache logic is operating towards the JS side of the application. Bettering the App Release Time Bettering the release time of your React Native application should also be a prime target of the developer. However, this can be a daunting task as you need to check each of the components to improve the performance of the libraries. So, if you want a desirable result here you should focus on the Object.Finalize element, which has been regarded as a key obstructer in decreasing the app performance. Thus, even if you are employing a subtle use of the finalizers, you will have to face the problems related to memory crash or errors, even after having sufficient memory space. The main reason why finalizers become barriers is because they operate on a single thread. So, if there are several finalizers that need to be run, you can simply image how much time they would eat up in this entire process. The Improvement in JSON Data The mobile applications are in search for a load resource getting it from the service or a remote URL with the intention of obtaining the requests to pull the data from the server. The data which they receive from the private or the public API are usually accessed in the form of JSON having some compound nested objects. The performance tends to slow down because the programmers store the same data to get an access to the local

You thought thinking up a killer idea was challenging. And then, developing a functional app was tough. But now, it’s up and running. So that means you can sit back and relax, right? Think again! The app market is competitive. Statista.com has the numbers. As of the third quarter of 2019, there are nearly 2,470,000 apps on Google Play and 1,798,000 apps on the Apple App Store. So you’re going to have to keep fighting to get noticed- that too, in a good way. You want billions of people across the world to use- and continue using- your app. Well, then you’ve got to keep pushing at making your app excel, boosting visibility, and retaining customer attention. You know that apps are beneficial to online businesses. Setting ambitious goals for delivering an unforgettable experience for your customers is part of your job description. So this means that you must quickly and efficiently investigate any issues to keep the responsiveness and performance of your app topnotch. And that can only be achieved through monitoring. Utilizing the appropriate tools to gain accurate and up to date insights is an ideal way to get ahead of the competition. How Can You Track Your App’s Performance? This is where app analytics comes into the picture. It captures data from mobile apps by identifying unique users, following their journeys, recording their behaviors, and providing reports on an app’s performance. Mobile analytics can be used to improve conversions by using data to create a better mobile experience. There are three uses for mobile analytics: Performance analytics- helps monitor an app’s efficiency Marketing analytics- tracks marketing campaigns In-app analytics- helps understand the mobile app user Why Should I Track the Performance of My App? Just last year, only 0.01% of all consumer mobile apps became financially successful, stated startupgrind.com. Scary, right? Well, that only enforces the fact that you cannot afford to let your app fail after all the hard work you put into launching it. There are several ways to keep tabs on your app. But before we get into that, here are the essential reasons why every developer needs to invest in keeping track of their app. Remain relevant to your customers Smartphones are a necessity, and brands are ignoring their importance. Through mobile apps, businesses are engaging with customers and empowering brands with extensive amounts of data. Tracking an app’s performance helps provide in-depth analytics on its adoption and usage as well as the user’s demographics. Using mobile analytics ensures that a brand remains relevant to its business goals and customers. If an individual doesn’t derive real value from an app, it will either be deleted or abandoned. Therefore, having the correct real-time data about customers is crucial for success. Do you know, 43% abandon the app a week after install, and 71% churn within 90 days? By monitoring changes in trends and preferences, a brand can maximize its efforts and continue to provide an app that is unique and valuable. There is always room for improvement Mobile analytics helps you assess consumer engagement and app performance. It is an integral part of the software development life cycle (SDLC). By gathering feedback and metrics, any brand will have the knowledge required to improve their current app. Developers have the power to make data-driven judgments about UX/UI, design, and content. This should be a continuous process so that the app can improve user engagement, increase user retention, and enhance the overall UX. Satisfy customer demands It’s always been- and will always be- about pleasing the customers. People are busier than ever. They want apps that can provide solutions to their problems while on the go- not get entangled with an app that keeps crashing. Apteligent stated that one in four users abandon an app after a single poor experience. Striving to achieve a 100% retention rate is unrealistic. But aiming to increase engagement and downloads is plausible. This will, in turn, gain more customers and attain growth. Therefore maintaining mobile app intelligence can help you highlight issues and rectify them as soon as possible. Apps need to optimize user experience and meet their expectations. Knowing what they are will keep you ahead of the curve. Gartner revealed that by 2018, 75% of organizations had redirected their investments to customer experience innovations. Get better than the competition There is a cutthroat in the digital world. Others in the same niche are ready to take as many customers as they can. Analytical tools can help you measure the performance of your business as well as others. So, depending upon the category that your app is designed for, consider monitoring the metrics of your competitors. From building brand awareness to communicating with your customers to getting viewers to take action, you now have the adequate tools to get ahead of the competition. You’ll know how the audience is engaging with your app and how they are interacting with it. Collecting the results daily, weekly, monthly, and annually will help you analyze trends and implement the right campaign for your business. In addition to app performance and behavioral metrics, you must also analyze industry data. Knowing how your app performs relative to others with respect to key app performance measures is vital for success. Utilizing reliable benchmarks for crash rate, app launch time, network latency, etc. can help analyze how your app compares with industry peers. The statistical analysis and insights can promote proper resource allocation, thereby improving your business. Allows brands to remain profitable Whether it’s through reviews, feedback, or analyzing data, determine what is making customers unsatisfied. By tracking the right metrics, you’ll be able to identify issues quickly and stay profitable. Engaging users and attracting new ones will help generate revenues. That’s why focusing on what’s driving ROI is essential. Buildfire claimed that 71% of app users churn within the first 90 days of downloading an app. By measuring metrics such as retention and churn, you can find out what’s causing these users to uninstall.
