What Top 8 Mistakes to Avoid While Working With React Native Apps

What is React Native? The React JavaScript library, the popular React Native framework, creates native mobile apps. It allows programmers to create cross-platform apps for iOS and Android using one code base, potentially saving them time and money. React Native development does, however, present a unique set of difficulties, much like any other technology.

Let’s begin! Did you know that Statista estimates there will be more than 3.8 billion smartphone users worldwide by 2021? In 2023, this figure is projected to increase to almost 4.3 billion. Given the rising demand for mobile apps, developers must avoid common blunders when using React Native so that their applications are highly calibrated and function effectively across various devices. In this article, we’ll discuss some typical errors programmers make when creating React Native apps.

What Mistakes Should Be Avoided While Working With React Native Apps?

The performance, functionality, and user experience of developers’ projects can be negatively impacted by mistakes when using React Native, just like with any other framework. Here are the top five pitfalls to avoid when developing React Native apps.

Not Optimizing the Application for Performance

Not optimizing the apps for performance is one of the most frequent errors developers make when using React Native. React Native offers incredible freedom, occasionally leading to poorly performance-optimized code. Keep your code organized and spotless to avoid making this error. Employ tools like the React Profiler to locate performance bottlenecks and address them before they negatively affect the user experience.

Utilizing the appropriate components is another way to improve the performance of your React Native app. Selecting the proper component for the job is critical because using the incorrect one can lead to delayed performance. For instance, the ScrollView component should only be used for small lists, while the FlatList component is a beautiful way to present extensive data lists quickly.

Neglecting Platform-Specific Rules

Although React Native is a cross-platform framework, it’s crucial to remember that the UI/UX standards for iOS and Android are different. Make sure your app looks and feels native on both platforms by using platform-specific elements and styles. Ignoring these recommendations could lead to an app that doesn’t fit its operating platform and looks and feels unnatural. Make sure to adhere to the platform-specific UI/UX design requirements to prevent making this error.

Too Many Libraries Used

You can extend the functionality of your project by using one of the many third-party libraries and components available for React Native. However, if you use too many libraries, your app will run more slowly. Eliminate unused libraries and utilize only those required for your project to avoid making this error—Utilize libraries with a solid performance history and good maintenance.

Not Thoroughly Testing Your Application

Testing is a crucial step in the creation of apps. Problems and errors may detract from the user experience if your software isn’t fully tested. Ensure to thoroughly test your software before making this error to avoid it. Write unit tests for your components using Jest and Enzyme, then end-to-end tests for your application using Appium and Detox.

Not Adhering to Recommended State Management Practices.

The creation of React Native apps requires careful attention to state management. Code that is difficult to maintain and prone to errors might result from not adhering to best practices for state management. Utilize a state management library like Redux or MobX to prevent making this error.

Improper Image Optimization  

Developers can increase the speed and storage effectiveness of their React Native apps by optimizing their pictures. The error of improperly optimizing photos in React Native apps causes sluggish app performance and extensive storage utilization. It is referred to as a “lack of native image optimization.” Developers should adhere to recommended practices, such as selecting the appropriate image format, resizing and compressing images, slow-loading images, caching images, and utilizing SVGs whenever available to prevent making this error.

Bad Coding Techniques

Bugs, subpar performance, and trouble growing and maintaining React Native codebases can all result from lousy development practices. Avoid everyday bad coding habits, including excessive use of state, poor component design, a lack of code comments, wasteful resource usage, and poor error handling. Developers should divide components into smaller portions, add comments to their code, utilize best practices and libraries to manage resources efficiently, and handle errors correctly to increase the quality of their code and the performance of their apps.

Missing Document Unit Tests

When developing React Native apps, it’s common to overlook document unit tests, resulting in bugs and subpar code. Document unit tests are crucial for detecting defects early in development and ensuring that code changes do not damage current functionality.

Writing and running unit tests for React Native apps should be a top priority for developers to prevent this error. All facets of the software, such as business logic, user interface components, and database interactions, should be covered in these tests. When making changes to the codebase, developers should also update the existing tests to guarantee that all functionality continues to function as intended.

Summing Up 

Building a mobile app using React Native can effectively reach a large audience on both iOS and Android platforms. However, it’s essential to avoid common mistakes while developing the app to ensure that it meets the high standards of quality, functionality, and user experience that customers expect.

By following best practices, optimizing images, avoiding poor coding practices, and prioritizing document unit testing, developers can build powerful, high-performing apps that deliver value to their users.
