Common Mistakes to Avoid When Developing React Native Apps

The React Native framework, which enables developers to create projects quickly, is widely used by entrepreneurs and developers. However, in keeping with the adage “prevention is always better than cure,” we have provided a safety guide for developers and business owners who have chosen React Native app development as their carapace through this blog.

Why Do Developers Prefer React Native?

Since React Native makes use of JavaScript,

One of the languages with which a developer begins their profession is JavaScript. They, therefore, closely resemble the subject matter in every way. The steep learning curve of React Native is significantly lowered because it mainly relies on JavaScript.

They can create native applications, too.

Even though the developers use JavaScript, they don't render React Native components using the web view. React Native should be your only option because it generates proper native elements, allowing developers to employ platform-specific features like activity indicators to give platforms a recognizable, native-like* feel.

A simple installation procedure

The installation process must always be straightforward, without any complicated procedures. Developers with a background in JavaScript will find the Node Package Manager to be a precise tool for installing the React Native framework. Even if you are unfamiliar with JS, React Native will save you the trouble of downloading binaries from the source.

Increased output

The productivity of the developers is the key to producing apps more quickly. Even if JavaScript is reliable, the procedure is still made simpler by the live reload capability and the user's option to use any IDE or text editor of their choosing.

Solid community support

Since its release in 2015, React Native has experienced significant growth in popularity. React Native has gained popularity among developers and companies from various industries thanks to its many advantages. As a result of this tremendous demand, a robust and active community has emerged that works every day to adapt to the benefits and drawbacks of React Native.

It genuinely works across platforms

React Native is a cross-platform app development framework, which means it can be used for more than just creating mobile applications. With React Native, developers can use their abilities on Windows smartphones, smart TVs, smart watches, and even VR headsets.

Obstacles in the Development of React Native Apps

Reliance on native app creators

Because of how JavaScript functions, developers occasionally rely on native developers, especially when the application must incorporate complex computing operations. These apps demand native developers because they force developers to offload computation to the native component of the app.

Abstraction Layer Restrictions

An abstraction layer is introduced to the native platform to allow for the expansion of functionality in React Native apps. The Abstraction Layer by itself has some recurring problems that should be avoided when developing React Native applications, such as:

• It is quite challenging to pinpoint issues that occur in the abstraction layer.
• High reliance on services and libraries provided by third parties
• Dependence on putting custom designs into practice

There is no support for parallel threading or multiprocessing

Because React Native only has one Javascript thread, developers who want to run multiple processes simultaneously may experience poor performance. It is a significant restriction of native response.

iOS deployment is very challenging.

Since they will have to deal with the challenges of obtaining provisioning profiles and appropriate certificates, many developers find it extremely frustrating when they choose to test their iPhone apps on any testing service other than Apple's Testflight when using React Native.

The procedure is not particularly challenging on Android, though, as testing and deploying Android apps is quite easy and hassle-free. As was previously discussed, React Native, like any other framework, has its share of difficulties.

It eventually boils down to the developers' experience. These difficulties would seem to be deal-breakers for novice or less experienced react native developers, but they won't be for experienced developers.

The 10 Common Mistakes in React Native App Development

Incorrect estimation

Versions of the layout for iOS and Android – Yes, there will be a lot of reused parts, but other layouts might also be possible. In reality, even the basic layout of an application page might vary greatly between iOS and Android.

Forms – you should also budget for the layout of the validation. React Native requires more coding than a hybrid platform like Cordova, so writing more code while creating an app in this framework is expected.

Check all the various backend endpoints that are available while building a Web app. And since you'll be handling the app's logic, everything should be properly coded. Understanding the database's organization, the relationships between its many entities, etc.

Ineffective redux store planning

When we receive an innovative project as developers, we put more effort into creating the app layout and less into the data handling portion of it. Redux aids with data storage and app state management during app debugging.

It can be a potent tool for controlling the app's data if well planned. When neglected, it can ruin a lot of things. Another thing to keep in mind while developing Redux apps is that they are not particularly well suited for small projects.

You will need to create numerous lines of code, even for little adjustments. Therefore, it would be better if you chose to avoid it when using React Native for startups and go with it for large scale projects.

Not reading external modules’ codes

It is not uncommon for us developers to save time through external modules. It makes things easier and faster, especially since it comes with documentation.

But, most often than not, modules break or they might not work as anticipated. This is the reason why developers should read the code and treat the step as one of the React Native best practices. Doing it helps to know what is wrong with the module and even how it can be solved.

State modification within the render function

The relationship between the Datastore and View is demonstrated in the graphic above. All of your data is stored in the datastore in the component, and the view is produced based on the current state. A fresh state is then taken from the data store and displayed on the screen.

React features a setState() function where the new object state is taken and compared to the prior state in order to accomplish it. After merging with the prior state, a new state is added and transmitted to the state datastore.

When you create an application using React Native, this cycle is accessible for the duration of a component's life.

Leave “console.log” statements in place

Statements in the console log are quite helpful. They even assist with app execution debugging. But what happens if the log statements are left in the app?

If you maintain the render methods and logic inside, especially asynchronous ones, this could become a severe problem and slow down JavaScript threading. All of this eventually causes the application to run more slowly.

Using stateless components to improve the speed of React Native

Some programmers continue to believe that what was true prior to React 16 is still true today.

A stateless component is one that doesn't extend any classes, in essence. In essence, it uses the argument as display and DOM properties. It offers advantages like

• Simple test of ability
• Speedy execution
• Does not use local variables or state

Not optimizing images for React Native

Optimizing the photos in React Native-built apps should be given top priority.

The work of optimizing the photos in React Native-built apps ought to be given top priority. It is beneficial to resize the images locally before uploading them to a cloud storage system like S3 and obtaining the CDN link, which can then be provided through the API.

Following this procedure makes it easier to load images quickly.

Prevent creating unit tests

A common error made when developing React Native apps is working without unit tests. This is because whether you write testing units or not, the developed app can still function. But it's a bet, and you won't know the outcome until you make your software available to users.

Therefore, it is preferable to test your app's functionality before releasing it on the market rather than leave its fate in the hands of users.
Writing unit tests will cut down on the drama that arises when an app is first released.

This not only streamlines the development process but also improves your app's reputation. The developers will be able to access different sections of the apps independently thanks to a well-documented unit test.

Therefore, always test each component at the appropriate stage to assure trouble-free operation. The error can also be caught early on by app developers, who can then fix it without pausing the entire development cycle.

Failure to follow protocol

You might regret not following the fundamental guidelines for developing React apps. As a result, developers and designers must constantly follow best practices. You get the React Native best practices that developers must adhere to with React Native.

Developers will impede the overall development process if they avoid using the accepted standards. The standard protocols must, therefore, always be adhered to and followed by the developers and designers.

Ignoring the structure of the project

The project structure cannot ever be overlooked or disregarded by developers. They ought to devote more time to regularly learning about the project. In the long run, it might have negative effects if they don't do this.

Having a project framework that is well-organized is crucial. Additionally, developers might aim to incorporate sound project architecture with React Native development. There could be more than 10, even if there are only 10.

Making as few errors as you can should be your ultimate goal as a developer. Let's wrap up this essay by examining what it would take to become a developer that avoids these blunders when creating React Native apps.

How Can I Develop Error-Free React Native Apps?

First things first: there isn't a single coder in the entire universe who is mistake-free.

Even programmers with ten to fifteen years of experience make blunders. Your goal after reading this essay shouldn't be to become an error-free developer. Your goal should be to avoid making the errors in React native app development that were highlighted in the article and are typically regarded as widespread in the mobile app development sector.

To achieve that, there are two options. How to design better React Native apps :

Enroll in classes and continue to improve your knowledge.

Starting your career off right by enrolling in classes will benefit you both now and in the future.

Even if you are skilled and have years of expertise, brushing up on the skills is still important. What occurs is that as your career progresses and you take on a range of assignments, you frequently lose sight of the technical knowledge you began with. Therefore, going back to the beginning and starting over always seems like a good idea.

Work for a business that emphasizes training.

This tip is more applicable to novice developers than to more seasoned ones. When you are just starting your career, you should work for a mid-sized company with Team Leaders who can help you put what you have learned in the classroom into practice.

The reason I say mid-sized companies is because tiny businesses typically operate on a time constraint approach and will expect you to be at the top of your game right away. Given this, it will always be preferable if you work with a mid-size company that will prioritize your learning.

Conclusion

React Native development includes all the necessary components to surpass other frameworks already in use. The sole caveat in this situation is that the developers must avoid these common errors.

React Native can therefore make you the greatest in the industry if you can eliminate all bad habits and keep your errors under control. You must discuss with a top React Native app development company to do this. Because the business will help you and give you the best service possible thanks to its experience. Additionally, developers working for an established React Native company are aware of the ramifications of their errors and avoid them.
