The Mistakes to Avoid When Creating a React Native Application

There are more than 1.6k active developers who continue to use React Native and make value additions for the code repository of the platform. Naturally, you can always count React Native as one of the most developer-friendly libraries used for building cross-platform apps. The library rose into so much popularity that we are already on the verge of comparing the native and React Native development. Continuous updates and value additions helped to advance the library further. 

But many React Native apps suffer from several crucial shortcomings in terms of performance and output. This is why we are here to explain the key mistakes that make the apps suffer.  But before getting into these challenges, let us explain the reasons that make React Native a loved solution for the developers. 

 

The Key Reasons for The Developers to Prefer React Native

Since React Native was unleashed by Facebook back in 2014, the library continued to become popular as a solution for building highly powerful native apps across the niches. 

Here are the key reasons that make developers prefer to React Native for building apps. 

  • React Native uses JavaScript which is a common and widely used language and is considered among the basic skills. 
  • Since Native apps are always popular over hybrid apps, React Native as a solution for building powerful native apps for multiple OS platforms always enjoys popularity. 
  • React Native also allows a direct and straightforward installation process through the Node Package Manager and this makes it easier for all developers to have a JavaScript background. 
  • React Native is a truly cross-platform library for building native apps for multiple platforms. With reusability of code and component-based architecture, it helps developing better cross-platform apps. 
  • JavaScript is a common language and the flexibility of using any IDE and live to reload features helps boost developer productivity to a great extent. 
  • Being in the app development scene since 2015, the library boasts of a large developer community with stronger support. 

Most important mistakes for developing React Native apps 

In spite of so many outstanding advantages that React Native offers for the developers, it has its own set of development challenges as well. Let us explain the key mistakes that developers commit while building React Native apps.  

 

Failing to Estimate the Development Tasks 

React Native will definitely offer you a comprehensive layout that you can use in building both iOS and Android apps. But at the same time, both these platforms may require different layouts. Moreover, the app page structure for both of these platforms is likely to be totally different on iOS and Android. 

In certain cases for creating the platform-specific layout for your app, you actually may need to write more code in comparison to building hybrid apps with tools such as Cordova. So, creating different layouts for two platforms for the same app you need to have a correct estimate. 

Similarly, for developing web apps you should evaluate the challenges involving the various endpoints from the app backend. As a web app requires handling the app logic right within the app, you need to code the business logic correctly in the app. 

 

Erroneous Planning For The Redux Store 

For most developers, it is common to plan more on the app layout while spending far less time and energy on handling the data. This is common particularly for app projects with a degree of uniqueness and innovative attributes. 

Redux is a key React Native feature that helps developers with respect to storing the data accurately besides taking care of app states and managing them. To utilize the full potential of the feature you should plan for using Redux storage to manage the app data correctly.  

In case your app project is a very basic and small one involving a very limited volume of data, you may not use the Redux feature that requires writing long lines of code even for small changes in the apps. 

 

Making Use of Uncertified External Modules

Many developers do not know how using external modules pull down the performance of their React Native apps. Most developers just use external modules without evaluating the code of these modules. All the developers who lack sufficient experience and knowledge make this common mistake. 

The coding errors and non-optimization of the code in these external modules can just result in underperforming apps and shortcomings in meeting the user expectations. This is why it is extremely important to verify the external modules before using them in an app project. 

 

Left of Console.log Statements

Console.log is another important inbuilt feature of the javascript which is widely used for detecting the bugs in a mobile application. The function works for both android and iOS applications. When developers use these statements, they can easily know the reasons behind performance dropout and it can also reveal the error in the code responsible for the performance glitches. 

Using this statement is quite ok for the developers for the express purpose of debugging. But many developers just leave the statement within the app code that slows down the app performance significantly. This is why developers after the debugging process is complete, should remove the statement. 

 

Making Use of Stateless Components 

There are many developers who just can’t see how after the coming of React Native the use of stateless components lost its appeal. We all know those stateless components by not extending any class allows easier testing and faster implementation. But these benefits of stateless components lost their meaning after React Native came. Let’s explain why developers don’t need stateless components. 

  • For building complex user interfaces React Native offers a shallow comparison feature that significantly reduces the render operations. It is simply possible because it comes with a robust life cycle method referred to as shouldComponentUpdate that on its own does a shallow comparison and evaluates the need for re-rendering.  
  • With React Native developers are also able to send AJAX request inside componentDidmount or can carry out other DOM operations. This is only possible if they refrain from using stateless components. 

 

Using Under-optimised Images

This is a very common and widely committed mistake of the app developers using React Native for developing apps. Under optimised images can significantly slow down the app performance and can create bottlenecks. Developers should use only optimised images for the projects.

 

Using Underperforming Project Structure

You also need to give extreme importance to project structure for building a great native app. Using a good structure will help you get the most out of a project. When you put filters and files in a simple and usable structure, it becomes easier for the developers to access the project ingredients. A good project structure also simplifies React Native development by allowing easier accessibility.  

 

Conclusion 

With a worldwide popularity React Native is likely to remain as one of the most preferred solutions for building powerful native apps for multiple mobile platforms. By keeping these mistakes in mind and preventing these errors the developers can actually get most out of the language for their app projects.
