Mistakes to Avoid on the Journey of React Native App Development

React Development
Developing React Native Apps

React Native, often said to be the “future of hybrid development”, is known for building robust and product-ready cross-platform mobile applications since it helps developers curb development time, ensuring instant compatibility with Android and iOS platforms.

However, app developers need to know the entire ecosystem like the back of their hands to make the most of this disruptive and versatile framework. 

Since the demand for this framework is increasing faster and is expected to go only far, having exhaustive knowledge is the only way app development companies can avert creating a mess with JavaScript syntax that can negatively reflect on the mobile application’s user experience.

This blog will state down the mistakes to avoid while React Native app development so that app developers be aware of the rookie mistakes and make the most from this versatile framework. Before we dive into the mistakes, let’s look at the advantages and challenges of React Native app development.

Why React Native Is a “Go-to” Choice For Developers?

  • Based on Vintage JavaScript

One of the scripting languages that developers start their careers in is JavaScript. As a result, they are very similar to the subject matter. Since React Native heavily depends on JavaScript, the learning curve is greatly reduced.

  • Ability to Create Native-Like Apps

Apart from the fact that app developers work with JavaScript, React Native doesn’t need WebView to render React Native components. The main reason for adopting React Native is that it renders truly native components. It allows app developers to use platform-specific elements such as activity indicators to give the platform a native-like experience, allowing developers to build responsive React Native apps.

  • Following Installation Instructions Are Easy

The installation process should always be simple, without complicated procedures. By using the Node Package Manager, developers experienced in JavaScript can easily install the React Native framework. Even if you don’t know how to code in JS, let us tell you, React Native app development saves you the hassle of fetching binaries from the source.

  • Greater Productivity

Developer’s productivity is the key to making apps faster. The stability of JavaScript has already made the process easier and includes a live reload feature and the ability to use any text editor or IDE. 


Hurdles in the Way of React Native App Development

  • Dependency on Native Developers

Given the nature of JavaScript, developers sometimes have to depend on native app developers, especially if the app requires a large computational process. These applications require the developers to outsource the computation to the application’s native part, which calls for the hiring of native developers.

  • Limitations in Abstraction Layers

An abstraction layer is injected into the underlying framework to add more functionality to your React Native app. The abstraction layer has some recurring issues that you should avoid when developing React Native applications. 


  • It is very difficult to trace issues that arise in the abstraction layer. 
  • It relies heavily on third-party services and libraries. 
  • Implementation of custom designs is required.
  • No Parallel Threading or Multiprocessing Capabilities

Since there’s only one JavaScript thread in React Native, developers may experience slow and static performance when running several processes in parallel.

  • iOS Deploying Is Highly Challenging

Testing iPhone applications on any testing service other than Apple’s Testflight is particularly awkward because when developing apps in React Native, developers have to deal with the complexities of obtaining appropriate certifications and provisioning profiles. 

However, on Android, the process is not that difficult because testing and deploying applications is a cakewalk.

As mentioned earlier, like any other framework, React Native is not without its specific difficulties. It all comes down to the developer’s prior experience. These issues might look like a deal-breaker for an amateur React Native developer but not for seasoned experts.


Mistakes to Avoid While Developing React Native Applications

React Native is said to be the “future of hybrid application development” since it put forward a plethora of tools and widgets to make mobile app development top-notch. But, if your chosen app development team is prone to making silly mistakes, you can’t use the framework.

Therefore, being the most reliable React Native app development company, we’ve listed the common mistakes to avoid to solve this problem. Avoiding these mistakes will enhance the entire mobile app development process, ensuring top quality and high performance.

  • Wrong Estimations

False estimations in React Native are one of the biggest mistakes. Yes, there are many reusable components that developers can use, but Android and iOS have different layouts. Also, the page structure can be completely different for both Android and iOS. So developers inevitably have to pay attention to details or waste a lot of time.

Developers should also avoid using external modules to save time because you can skip the code extracted from the module. This habit of ignoring the code can ultimately cause serious problems.

Also, adding external modules can interfere with existing code and make it difficult to operate. So, developers should avoid these React Native app development mistakes and pay attention to details. 

  • Incorrect Setup or Planning of Redux Store

When it comes to React Native app development, developers often emphasise planning the app’s layout and focus less on the data handling segment of the project, which makes managing the application and its data a bit tricky. This is where Redux comes to the rescue.

Redux is a robust tool that helps store your application data correctly and manage effectively. One important thing about Redux is that it is better suited for large-scale applications. Even for minor changes, you need to write lengthy codes. So, it’s better to choose Redux for heavier applications and avoid it for smaller projects.

Moreover, Redux must also be properly planned or configured. Otherwise, it can mess up the debugging, application’s data flow, logic tests, etc. In this regard, you must:

  1. Arrange your files by forming a store hierarchy;
  2. Integrate the first reducer function;
  3. Incorporate more reducers fuse them;
  4. Add middleware;
  5. Set up or configure the store.
  • Unoptimized Images

When developing React Native applications, we’ve often noticed that developers leave the images unoptimized. This is a bigger problem since unoptimized images gobble up a lot of memory and space. Image optimization should be your top priority as it directly impacts the app’s performance. It also frees up memory and storage space. As a leading mobile application development company, we optimize images by:

  1. Resizing the image into a contracted size before uploading the image into React;
  2. Using only the WebP image format to speed up loading time and reduce binary and batch sizes;
  3. Giving priority to PNG format over JPG;
  4. Caching images locally.


  • Usage of Stateless Components

Stateless components used to be a great option for app developers to enhance React Native performance up until version 16.0, but not now. Some developers still use it, but now it’s not very effective. 

Stateless components do not extend any classes and have no local variables. They return what is assigned in the DOM. They offer features that are easy to test and help in rapid deployment, enabling teams to bring products faster to the market. However, they are not considered ideal for this scenario.

React Native’s  replacement with pure components appears to be the best choice to speed up the development process and increase productivity. The reason developers prefer this is mainly because of the superficial comparison. This is useful for applications with complex user interfaces since it reduces the render operations. It uses a lifecycle method that automatically performs shallow comparisons and checks to see if they are re-rendered. 

Unlike stateless components, where re-rendering occurs when the parent component is re-rendered, a pure component is only re-rendered when a change is identified in the property state.

  • Not Paying Attention to Protocols

Strictly not adhering to the basic protocols of React Native application development can result in your app falling into deep waters. Therefore, designers and developers should always follow the best practices. The React Native development framework has many scripting practices that app developers must follow. 

For example, developers should adhere to naming conventions to improve the code’s readability. Furthermore, abandoning standard protocols complicates the entire development process. Thus, designers and developers should always adhere to standard protocols.

  • Left ‘console.org’

Developers should always avoid using log statements in their applications themselves. However, the console log statements that help with the debugging process of applications tend to be very simple. However, problems can arise if developers continue to display out-of-sync logic. 

It’s no exaggeration to say that unsynchronized logic can overload JavaScript streams. All of these overloads accumulate and ultimately degrade the performance of the device. 

Therefore, developers should use log statements wisely when developing React Native apps. The application should not leave any log entries.

  • Not Executing Unit Test

Another major mistake that app developers make when developing React Native applications is not executing unit tests. Most developers ignore this step because they are used to working without unit tests. However, going through the development process without performing unit tests can be risky. 

Resolving the errors and bugs at the last minute post-deployment can be a strenuous job. When a defective product is disclosed, it negatively impacts both the product and the brand. The best way to avoid this is to carry out functional testing to ensure every element works seamlessly before the product launch. This is where unit testing comes to the rescue.

Unit tests allow developers to test individual components or modules of an application to ensure that each component behaves as expected. This is done in the development phase (coding stage) to fix bugs early and save the developer’s time and your money in the end.

  • Bad Coding Practices

One important thing that you must understand is that your app cannot scale if you leverage bad coding techniques. To make matters worse, you have to change your code from time to time (if requirements exceed). And because the code is not extensible, you are bound to pen a huge amount of code. As a leading destination for React Native app development services, we give you the solution to end this issue. 

Don’t plan if you’ve already started coding. Make a plan and start programming. Follow best coding practices to ensure the code is readable. For example, use property restructuring. Divide the rendered components into readable helper functions. Use meaningful names for variables to identify the component’s property types, methods, individual life cycle, etc.
