7 Mistakes To Avoid When Developing React Native App

Updated on Apr 15th, 2024

One of the most prominent cross-platform app development frameworks which allow programmers to develop top-notch and scalable applications is React Native, created and launched by Facebook. The benefit of using this framework would be that it comes with the potential to reuse the code, allowing programmers to use the same codebase with streamlined User Experience to build both Android and iOS applications. As per many developers, React Native is the most versatile and impressive platform, because it not only improves the pace of development with all its open-source modules, but also lowers the development cost. Which means a single codebase can be utilized across both Android and iOS or any other platforms.

React Native Framework

Why React Native is So Popular Among Developers?

The reason behind the popularity and a big community is their benefits. Below we’ve mentioned some of them.

  • Offers Cross-Platform capabilities.
  • Uses JavaScript.
  • Best memory management.
  • Supports third-party plug-ins.
  • Simple and straightforward installation.
  • Conversion of web app to mobile app made easy.

Even so, while using the React Native framework to practice the process of Android and iOS app development, many programmers also appear to face difficulties and make some obvious errors that can mess up the application’s user engagement and impressions. Many of such mistakes are commonly due to certain attributes being ignored and are totally preventable. In this blog, we have outlined and clarified the 7 most common errors that you should avoid in order to maximize the efficiency and effectiveness of React Native Application.

But, let’s discuss.

Challenges in React Native App Development

Dependency on Native Developers

To grasp how JavaScript works developers almost always have to depend on Native Application Developer. Particularly when you’re about to bring heavy computing operations into the app. Such categories of applications compel developers to import functionality to the native portion of the application that needs a native developer to do it all.

Flaws in Abstraction Matrix 

To offer the React Native Application more functionality, an abstraction layer is installed on the native framework. In the development of React Native Applications, Abstraction layer alone has some persistent challenges and conflicts that need to be managed such as:

  • It is difficult to determine bugs and errors that are found in the abstraction layer.
  • Strong reliance on resources and libraries from third parties.
  • Dependence on custom designs being implemented.

None Multiprocessing Aid or Parallel Threading Support

React Native consists of a single JavaScript chain, which enables programmers to experience low throughput when they choose to run asynchronous processes.

Difficult Deployment in iOS 

Throughout the case of React Native, programmers find it immensely maddening whenever, in response to Apple’s Testflight, they would like to test their iPhone application on just about any testing services, particularly as they’ll have to deal with problems of getting the necessary supply labels and certificates. Nevertheless, the process wasn’t very complex and nuanced on iOS, as it is very straightforward and hassle-free to test and release Android Applications. Knowledge of mistakes that really should be omitted to create a React Native error-free application is the only distinction between a competent and incompetent React Native Developer.

Every framework has its own benefits and challenges. As of now we’ve discussed both top benefits and challenges. In the coming section, we’ll be looking at common mistakes every developer commits inadvertently.

So without taking much of your time, let’s get directly into it.

Top 7 Common Mistakes in React Native App Development

1. Wrong Projections
2. Wrong Preparation for the Redux Store
3. Not Optimizing the Images
4. Leaving Log Statements
5. Not Following Tests
6. Not Reading External Modules Properly
7. Disregarding Project Structure

1.Wrong Projections

Code reusability has been one of the central aims of using React Native. Native developers though, frequently make a common mistake, ignoring that an application page for both Android and iOS platform can differ and vary significantly in its page layout. For Android and iOS platforms, a lack of experience and understanding of design principles and formats standards leads to inaccurate (wrong) estimations. You won’t believe an experienced, professional developer or a development firm should always plan evaluations separately for Android and iOS platforms. Secondly, when developing a web application, to control the logic and setting up the right codes in your web application, it is very important to verify all the database and backend nodes. You also must concentrate on the authentication structure, not just forms, so that later you will not get any sort of authentication problem or mistakes.

2.Wrong Preparation for the Redux Store

Redux is a versatile tool that helps to manage an app effectively. It also lets you accurately store data collected by the application. Redux is commonly used for the handling of bulkier apps. To prevent problems, nevertheless, you must prepare it properly. The amount of workload can also be increased by more use of Redux. While for big applications and ventures, it might seem acceptable, it is not appropriate for small applications and ventures. Why so? That’s because, for the shorter of modifications, Redux needs you to write long, complicated codes. So, it’s better not to use Redux if you are building a React Native Application for small scale.

3.Not Optimizing the Images

This has been the most prevalent mistake made by developers even during development of React Native App. Enhancing the images in a React Native App is an important component and optimum focus must be concerned, as an application’s output relies heavily on image optimization. Unoptimized images not only require huge memory and storage but also significantly decrease the app’s efficiency. For effective image optimization, here’s some advice.

  •  Use images of small size
  •  Use PNG format.
  •  For fast loading, catch your images locally.

4.Leaving Log Statements

A developer could use console log statements while building a React Native Application. This helps them to debug the application during the strategic stage and makes sure it is bug-free. Although, before continuing, you must delete all the log declarations. Developers sometimes fail to delete the log statements for the console. This can contribute to a serious problem. In particular, this arises when both rendering and logics methods are used in application. So then, these log statements can end up being JS thread congestion. In essence, it leads to an app that is stuttering and sluggish to perform.

5.Not Following Tests

A bad decision that one might make when working on a project is not following the coding best practices for React Native. There are several broad and specific React Native coding best practices you can adopt, while developing you application using this framework. For instance, you must adopt the naming conventions, and strive to enhance the code’s readability. This could delay the process of application development if the coding practices are not followed and can also decrease the application’s efficiency and overall quality. So then, you should definitely follow the best practices for coding.

6.Not Reading External Modules Properly

For programmers, it’s not unusual to save time via external modules. In particular, because they come with paperwork, it makes things simpler and quicker. Although modules split, more often than not, or they may not function as planned. This is why programmers are expected to read the code and consider the move as being one of the best practices of React Native. Doing this really helps to understand what’s wrong with the module and also how to fix it.

7.Disregarding Project Structure

The incorrect structure of the project will make it difficult for you to function with and to manage the project. It is possible to organize a project in many ways. Ordered project files and directories are going to make a developer’s life much easier.  Beginners typically don’t really spend much time on the structure of the project, not understanding that in the future it could lead to issues. It is very crucial to have a strong project structure. So, with your React Native App, you can strive to incorporate the greatest project structure.

Bonus Point: Passing Parameters & Binding in the Render Method

In the render process, if you had ever considered binding? Each time, this introduces a new approach instead of only taking up the previous approach or method. The problem with an approach that React Native Developers usually ignore is the multiple callbacks. This can be fixed with the handleWatchList() approach in constructor or in props initializer syntax. In order to get the desired outcome, it is therefore necessary to transfer the values of handleWatchList() as props. For these kinds of modifications, the child component may be a strong benefit.

Lastly, there is not even a solitary developer on the globe who doesn’t make mistakes. You won’t believe even programmers with years of experience make mistakes. In the end of this blog post, your aim should not be to become a programmer who does not make mistakes, it must be that you don’t make mistakes as mentioned in this blog.
