10 Mistakes to Avoid When Developing React Native Apps


The 10 Common React Native App Development Mistakes

  1. Wrong estimation

Layout for iOS and Android model – Yes there will be a number of reusable components, but there may want to also be different layouts. In fact, the mere shape of an application page can be totally different on iOS and Android completely.

Forms – you should estimate the validation format as well. When you create an app in React Native, you are supposed to write more codes compared to when you create a Hybrid app on consider Cordova.

The main difference between Django and Node. js is that Django is a high-level Python web framework that encourages rapid development to facilitate web developers in developing applications timely and swiftly.

If creating a Web app, you should test all the different endpoints which are offered via the backend. And because you will have to handle the common sense in the app, it should all be coded correctly. You should apprehend the database structure, how the entities are connected, etc.

  1. Wrong redux store planning

As a developer when we get an innovative project, we focal point more on planning the app layout and much less on the data handling section of it.

Redux aids in the accurate storage of data and the management of debugging app states. When deliberate right, it can be a powerful tool for managing the app data. When not, it can mess up many things.

Another factor to note in case of Redux app development is that it is now not extremely suited for small projects. Even small adjustments will ask you to write long lines of codes. So, it’ll be higher if you choose to go with it for large scale purposes and avoid it when choosing React Native for startups.

  1. Not studying external modules’ codes

It is not individual for us developers to save time via external modules. It makes things less complicated and faster, especially since they come with documentation.

But, most frequently than not, modules break or they might no longer work as anticipated. This is the reason why developers have to read the code and treat the step as one of the React Native exceptional practices. It allows you to figure out what’s wrong with the module and how to fix it.

  1. Mutation of country inside render function

The image above highlights how the Datastore and View are interconnected. The datastore carries all your data in the component and the view is rendered on the foundation of state. It then consumes a new state from the data keep and shows it on the screen.

In order to achieve that, React has a setState() characteristic where the new object state is taken and in contrast to the previous state.

Finally, a new state is introduced after merger with the previous state and despatched to the state datastore.

This cycle is available all all through the lifetime of a component when you develop utility in React Native.

Now, if you mutate the state directly, the lifecycle gets messed up and it corrupts all the preceding states. This leads to apps behaving abnormally or even crashing. This will also result in you dropping track of the states across factors and will lead to you writing custom code in place of React. Additionally, you’ll quit up having an unmanageable code and a heavy app.

  1. Left “console.log” statements

Console log statements are extremely handy. They even provide assistance with debugging the app execution. But what happens if the log statements are left in the app?

This can turn out to be a serious issue if you keep the render techniques and logics inside, especially those which are asynchronous for they can lead to a bottleneck in JavaScript thread. All this in the end leads to the application becoming slower.

  1. Using stateless issue for gaining React Native performance

Some developers still assume that what was true earlier than React 16 is true even now.

Stateless aspect basically means that the element does not extend any class. It essentially takes the argument as display and props in the DOM. It comes with benefits like –

  • Easy checking out ability
  • Fast implementation
  • Does not use nation or the local variables

With the time changing, it has today turn out to be wiser for developers to use pure component when they create React Native apps. Here’s why –

Performs shallow evaluate – This is a special win for complex UI purposes as it lowers the render operations. The reason behind it is that it comes with a existence cycle method known as should Component Update which routinely does shallow comparison and then check if re-render is needed. In the case of stateless component, re-render occurs when the parent component re-renders. But in the case of pure component, re-render solely happens when a change is detected in the states or props.

Performs aspect effects – Developers can even send AJAX requests inner component Did mount or can perform some other DOM operations.

  1. Not optimizing React Native pix

Optimizing the images in apps built with React Native ought to be a high priority task. It helps to resize the pictures locally and then uploading them to cloud storage like the s3 with the aid of server and getting the cdn link which then can be returned the usage of API.

Following this procedure will speed up the image loading process.

  1. Avoid writing a Unit Test

Working except unit tests is a big React Native app improvement mistake. This is because the developed app can still work regardless of whether or not you write testing units or not. But, it is a gamble the place you only find the end result once you launch your app for customers.

Therefore, rather than leaving your app’s destiny at the mercy of users, it is better to test its performance before launching the product in the market.

Writing unit tests will minimize the unnecessary drama caused at the time of app launch. This no longer only eases the development technique but it also increases the reputation of your app as well. A well-documented unit test will permit the developers to access specific parts of the apps separately. Thus, always check every element at the right stage to ensure hassle-free working. App builders can also spot the mistake at an early stage and rectify it without worrying the entire development process.

  1. Not paying heed to protocols

Not adhering to the fundamental protocols of React App development could show to be a huge mistake for you. Thus, developers and designers ought to always follow the fine practices. With React Native you get the react native best practices that the developers ought to follow. If developers keep away from the preferred protocols, it will hinder the overall improvement process. Therefore, the developers and designers must constantly stick to and follow the standard protocols.

  1. Ignoring the mission structure

Developers must never forget about or ignore the project structure. They have to invest more time in mastering about the project normally. If they don’t do this, it could end result in bad outcomes in the lengthy run. Therefore, it is essential to have a well-organized project framework. And with React Native development, the builders can aspire to integrate good challenge structures.

While these are only 10, there can be a series of others as well. As a developer, your final aim should be to make as few errors as possible.

Let us conclude the article by looking into what it would entail to turn out to be a developer who doesn’t commit these React Native app development mistakes.

How Do You Become a React Native App Developer Who Doesn’t Make Mistakes?

First thing first, there is now not even a single developer on planet Earth who doesn’t commit mistakes.

Even developers with 10-15 years of experience commit mistakes. Your goal at the end of this article should no longer be to become a developer who doesn’t commit mistakes. It should be that you don’t commit the React native app improvement mistakes mentioned in the article and ones which are usually categorized as common in the cell app development industry.

There are two ways to do that. Ways to turn out to be better React Native app developers –

  1. Enroll in publications and keep brushing up your skills

Enrolling in publications at the beginning of your career can be a remarkable starting point on the current and future grounds.

Brushing up on the skill is equally necessary for when you are professional and have years of experience. What happens is when you expand your profession and work on a variety of projects, you most often than now not lose sight of the technical understanding that you started with. Thus, it usually comes across as a plus point to get again to the basics and revise things from scratch.

  1. Associate with a enterprise that focuses on training

This part is greater valid for newbie builders compared to their experienced counterparts. When you are simply starting your career you need to associate yourself with a mid-sized organization that has Team Leaders to hand-hold you through the practical software of what you learned on an academic level.

The cause I say mid-sized company is because a small sized organisation usually operates in a time crunch model, so will be working under the expectation that you will be on your A recreation from day one. Considering this, it will always be better if you companion with a mid-size business who will focus on your learning.

FAQs About React Native App Development Mistakes to Avoid

  1. How do you enhance react native performance?

There are multiple ways to enhance the performance of your React native application:

  • Avoid unnecessary renders
  • Use PureComponent rather of Stateless
  • Optimize the JSON data
  • Lower the app size
  1. Why use Redux with react native?

Redux tool helps in storing  and managing the data, debugging app states. When deliberate right, it can be a powerful tool for managing the app data. Although regarded beneficial, Redux is best suited for the improvement of complex applications as in contrast to simple apps, for the number of codes are higher.

  1. Is React Native well worth using?

React Native’s way of creating mobile apps for more than one platforms using solely one JavaScript codebase makes it worth using.
