Seven Errors to Evade When Building a React Native Application

Latest Blog Post Image

Constructing an app with React Native calls for knowledge of JavaScript, React.js, and the React Native framework. Crafting the code and constructing the app is a lengthy and demanding process, and even more time is necessary to guarantee its performance is satisfactory. React Native has the potential for creating intricate apps, but it can be easy to make errors if you are inexperienced.

It's essential to be aware of the potential risks that come with any technology prior to utilizing it. There are multiple errors which can be prevented when developing a React Native app. This article aims to guide you in recognizing and avoiding those missteps in order to guarantee the success of your app.

It's important to avoid the following 7 missteps:

A different form of the same idea can be stated as follows: It is possible to alter the arrangement of the words in a sentence without changing the overall meaning.

1. Entries recorded in the application:

A log statement is necessary in an application for it to be debugged, providing a smooth operation during its running phase. Nevertheless, these log statements must be eliminated ahead of handling React Native apps.

As per the documentation, React Native notes that when running a packaged app, calling functions from debugging libraries such as redux-logger can greatly slow down the JavaScript thread. Thus, it is imperative to eliminate these calls prior to bundling.

Before you publish the application, make sure to take out any log statements.

2. Not optimizing pictures

It is easy to overlook the importance of optimizing photographs, but it can have a significant impact on web page performance. Making sure images are compressed and formatted correctly, and that the file sizes are as small as possible, is essential for creating a website that loads quickly and efficiently.

React Native can process a range of image formats, but not all of them are optimized for mobile devices. Those with a large size and high resolution can consume a great deal of memory and may lead to a laggy performance. This can be an especially significant problem on devices with limited resources, as loading these types of images over a network can cause the application to take an extended time to load, resulting in a poor user experience.

Without damaging the quality, developers are able to reduce the size of photographs through optimization. Doing this will help to lessen both the memory usage and the loading time. There are various ways to accomplish this, and the correct format, compression, and resolution can be employed depending on the purpose.

3. Unsuitable preparation of redux storage

Redux is a helpful instrument for effective management of an application. It also allows for safeguarding the data collected by the app in the right way. Redux is generally used to supervise more complex, heavier applications.

React Native makes use of Redux, so it is essential to plan it out properly in order to avoid complications. When Redux is employed more often, the workload could increase which might be suitable for extensive projects but not for smaller ones.

Redux necessitates an abundance of complex coding, even for minute modifications, which makes it an impractical choice for the development of small React Native applications. Consequently, it is recommended to avoid Redux for such projects.

4. Failing to build unit tests

Developers often make the mistake of neglecting to do unit testing when they are building React Native applications. Most software engineers are unaccustomed to writing tests, so they tend to skip this step. However, it is dangerous to progress in the development process without having a unit test in place.

Making sure that all parts of the product are working correctly before it is released to the public is the best avenue to prevent any issues. If there are flaws with the product after it has been launched, it will be not only detrimental to the product but also to the company's reputation. Therefore, testing and double-checking the product prior to its launch is essential.

5. Miscalculated assessment

For both iOS and Android, there will likely be some elements which are reused, but other design configurations may be possible as the fundamental layout of an app page can differ significantly between the two platforms.

When working with forms, it is necessary to allocate a budget for their validation. As React Native requires more coding than hybrid frameworks such as Cordova, the user should anticipate needing to write more code while creating an app with this framework.

Before creating a Web application, it is important to take a look at all the different backend APIs that are available. As the user will be responsible for the app's logic, it is essential to make sure all the code is correct.

It is also necessary to be familiar with the structure of the database, the connections between its various components, etc.

It is possible to avoid plagiarism by altering the way the text is written without changing the context or the semantic meaning. This can be accomplished by restructuring the text while still preserving its formatting.

It is possible to avoid plagiarism by reworking the structure of a text without altering the general context and meaning. This can be done by ensuring that the markdown formatting is retained.

6. Utilizing stateless components

With React 16, the stateless component was an excellent choice to improve React Native speed; however, it is no longer a viable option. Despite its diminished effectiveness, some individuals still make use of this approach.

A component without any internal state consists of no specific local variables or class extensions, instead it merely returns the data that was passed to it in the DOM. This makes deployment and testing much faster and allows the team to introduce the product to the market in a timely manner. Even so, these components do not always provide a perfect solution for the current case scenarios.

7. Neglecting accepted programming protocols

React provides a set of methods and programming standards that can be utilized; however, not many pieces of code adhere to these rules. These procedures could improve the development process.

Attention to readability and brevity must be given to your code when composing it. If this isn't handled quickly, the project could be hindered by a considerable amount of resources and time.


Creating a React Native app can be an effective strategy to reach a wide range of users and improve their engagement. If not done properly, however, it can be a waste of resources and lead to a bad user experience. This post discussed six missteps to evade when developing a React Native app, such as leaving log entries in the app and disregarding good coding practices.

Developers can construct an efficacious React Native app that fulfills their users' necessities and prevents expensive errors with the help of the correct information and prudent planning.

If you are in need of a developer who can construct a React Native app for your company, then it would be a good idea for you to get in touch with one of the top rated mobile app developers. Mobulous is just one of the highly regarded mobile app developers. Reach out to us now to talk about your project.

It is possible to eliminate plagiarism by transforming the structure of a text without altering the context or semantic meaning. This can be accomplished by retaining the same markdown formatting.
