10 Mistakes to Avoid When Developing React Native Apps

With over 1.6k energetic contributors working to make React Native successful, the glitter of a vibrant framework future has not gone unnoticed by builders seeking to make a reputation within the cross-platform world.


Table of Contents

The demand of app improvement with react native is getting from the builders is not only the doing of the truth that the trade has grown to an extent the place it’s now evaluating Native and React Native modes of improvement. The demand can also be pushed by the fixed updates that make the framework superior.

This demand, although, can solely go up to now. In the end, on a floor degree, builders must study their approach across the improvement course of. Particularly on the entrance of understanding and avoiding React native app improvement errors which may wreck the customers expertise and their abilities.

We have now divided the article into 4 sections to ease the method of getting accustomed with the errors confronted throughout React Native app improvement and know what it will take to turn out to be a developer that commits minimal errors.

Why do Builders Love React Native?

1. As a result of React Native makes use of JavaScript

JavaScript is likely one of the languages that a developer begins their profession with. And they also have a really detailed resemblance with the subject material. The truth that React Native depends closely on JavaScript brings down the learnability curve to an incredible extent.

2. They get to construct native functions

Regardless that the builders work on JavaScript, they don’t use net view for rendering React Native elements. The one cause why it is best to select React Native is as a result of it renders actual native parts, giving builders the flexibleness to make use of platform particular elements comparable to exercise indicator, which provides very platform a recognizable, native-like really feel.

  1. A simple set up course of

4. Higher productiveness 

The important thing to constructing apps quicker lies within the builders’ productiveness ranges. Whereas the reliability of JavaScript already makes the method simpler, it additionally comes with a reside reload characteristic and the liberty to make use of any IDE or textual content editor of their selection.

5. Sturdy group backing 

React Native has gained a whole lot of reputation ever since its launch in 2015. Builders and companies from all throughout the globe and industrial background have chosen to go along with React Native in the back of the plethora of advantages it provides.

This excessive demand has in flip resulted within the creation of a powerful widespread group engaged on adjusting the React Native execs and cons every day.

6. It’s really cross-platform 

After we say React Native is a cross-platform app improvement framework, we don’t simply imply utilizing React Native for cellular app improvement. Utilizing React Native, builders get to broaden their abilities to good TVs, good watches, Home windows units, and even VR headsets.

Even amidst these and several other different un-mentioned advantages of React Native improvement, there are some reactjs challenges that inherently come related to React Native app improvement. Challenges that skilled builders have come to simply accept and work round. To eradicate the reactjs challenges, wherever you might be positioned, be it Los Angeles, New York, and so on, it’s advisable to rent a React Native App Developmen Firm in New York to construct and develop customized react native apps with the most recent options.

Challenges Related to React Native App Improvement 

1. Dependency on Native app builders 

Noting how JavaScript works, builders generally must depend on native builders as properly. Particularly when it’s a must to put heavy computational operations within the software. These apps power builders to dump computation to the native a part of the app, which in flip requires a local developer.

2. Limitations in Abstraction Layer 

In an effort to add extra performance within the React Native apps, an abstraction layer is added on native platform. Abstraction Layer in itself comes with some persistent points – the points to keep away from in React Native app improvement – like:

  • Figuring out bugs which get encountered within the abstraction layer is extraordinarily tough.
  • Excessive dependency on third-party providers and libraries
  • Dependency on implementing customized designs

3. Zero help for multiprocessing or parallel threading 

React Native contains a single Javascript thread due to which builders may observe gradual performances once they wish to execute any processes in parallel. It is likely one of the main react native limitations.

4. iOS deployment is especially tough 

In the case of React Native, builders discover it significantly annoying once they determine to check their iPhone app on any testing providers in addition to Apple’s Testflight, particularly since they must take care of problems with acquiring provisioning profiles and crucial certificates.

The method isn’t very tough on Android although, as it is rather easy and hassle-free to check and deploy Android apps.

As talked about earlier than, React Native, like another framework doesn’t come freed from challenges. It in the end comes right down to the expertise of the builders. For a beginner or much less expert react native builders these challenges would seem as deal-breakers, whereas for expert builders it received’t.

The one distinction that stands between a talented and unskilled React Native developer is the data of errors that must be averted with a view to construct an error free React Native app.

What makes React Native difficult for some is not only the inherent framework limitations but additionally the React Native app improvement errors that builders unknowingly commit. 

The ten Widespread React Native App Improvement Errors

1. Incorrect estimation 

  • Format for iOS and Android model – Sure there will probably be plenty of reusable elements, however there is also completely different layouts. In actual fact, the mere construction of an software web page will be fully completely different on iOS and Android fully.
  • Varieties – it is best to estimate the validation format as properly. Once you create an app in React Native, you might be supposed to write down extra codes in comparison with if you create a Hybrid app on suppose Cordova.
  • If making a Net app, it is best to examine all of the completely different endpoints that are provided by the backend. And since you’ll have to deal with the logic within the app, it ought to all be coded accurately. You must perceive the database construction, how the entities are related, and so on.

2. Incorrect redux retailer planning

As a developer once we get an revolutionary undertaking, we focus extra on planning the app format and fewer on the info dealing with a part of it.

Redux helps in storing the info accurately and managing debugging app states. When deliberate proper, it may be a strong device for managing the app information. When not, it may well mess up many issues.

One other level to notice in case of Redux app improvement is that it isn’t extraordinarily fitted to small tasks. Even small adjustments will ask you to write down lengthy strains of codes. So, it’ll be higher for those who select to go along with it for giant scale functions and keep away from it when selecting React Native for startups.

3. Not studying exterior modules’ codes 

It isn’t unusual for us builders to avoid wasting time by means of exterior modules. It makes issues simpler and quicker, particularly since they arrive with documentation.

However, most frequently than not, modules break or they may not work as anticipated. That is the explanation why builders ought to learn the code and deal with the step as one of many React Native finest practices. Doing it helps to know what’s unsuitable with the module and even how it may be solved.

4. Mutation of state inside render perform

The picture above highlights how the Datastore and View are interconnected. The datastore incorporates all of your information in the element and the view is rendered on the idea of state. It then consumes a new state from the information retailer and exhibits it on the display screen.

In an effort to obtain that, React has a setState() perform the place the brand new object state is taken and in comparison with the earlier state.

Lastly, a brand new state is added after merger with the earlier state and despatched to the state datastore.

This cycle is accessible all all through the lifetime of a element if you develop software in React Native.

Now, for those who mutate the state immediately, the lifecycle will get tousled and it corrupts all of the earlier states. This results in apps behaving abnormally and even crashing. This will even end in you dropping monitor of the states throughout elements and can result in you writing customized code rather than React. Moreover, you’ll find yourself having an unmanageable code and a heavy app.

5. Left “console.log” statements

Console log statements are extraordinarily helpful. They even present assist with debugging the app execution. However what occurs if you go away the log statements within the app?

This may turn into a severe difficulty for those who preserve the render strategies and logics inside, particularly these that are asynchronous for they’ll result in a bottleneck in JavaScript thread. All this in the end results in the appliance changing into slower.

6. Utilizing stateless element for gaining React Native efficiency

Some builders nonetheless suppose that what was true earlier than React 16 is true even now.

Stateless element mainly signifies that the element doesn’t lengthen any class. It mainly takes the argument as show and props within the DOM. It comes with advantages like –

  • Straightforward testing capacity
  • Quick implementation
  • Doesn’t use state or the native variables

With the time altering, it has immediately turn out to be wiser for builders to make use of pure element once they create React Native apps. Right here’s why –

  • Performs shallow examine – It is a particular win forcomplex UI functions because it lowers the render operations. The rationale behind it’s that it comes with a life cycle methodology often known as shouldComponentUpdate which routinely does shallow comparability after which examine if re-render is required. Within the case of stateless element, re-render occurs when the guardian element re-renders. However within the case of pure element, re-render solely occurs when a change is detected within the states or props.
  • Performs uncomfortable side effects – Builders may even ship AJAX requests inside componentDidmount or can carry out another DOM operations.

7. Not optimizing React Native pictures 

Optimizing the photographs in apps constructed with React Native must be a excessive precedence job. It helps to resize the photographs regionally after which importing them to cloud storage just like the s3 by server and getting the cdn hyperlink which then will be returned utilizing API.

Following this course of, helps make the picture loading course of quick.

8. Keep away from writing a Unit Check

Working with out unit exams is a giant React Native app improvement mistake. It’s because the developed app can nonetheless work no matter whether or not you write testing items or not. However, it’s a gamble the place you solely discover the end result when you launch your app for purchasers.

Subsequently, somewhat than leaving your app’s destiny on the mercy of customers, it’s higher to check its performance earlier than launching the product available in the market.

Writing unit exams will scale back the pointless drama triggered on the time of app launch. This not solely eases the event course of nevertheless it additionally will increase the repute of your app as properly. A well-documented unit check will enable the builders to entry completely different components of the apps individually. Thus, at all times check each component on the appropriate stage to make sure hassle-free working. App builders also can spot the error at an early stage and rectify it with out disturbing your complete improvement course of.

9. Not paying heed to protocols

Not adhering to the fundamental protocols of React App improvement may show to be an enormous mistake for you. Thus, builders and designers should at all times observe one of the best practices. With React Native you get the react native finest practices that the builders should observe. If builders steer clear of the usual protocols, it’s going to hinder the general improvement course of. Subsequently, the builders and designers should at all times follow and observe the usual protocols.

10. Ignoring the undertaking construction

Builders mustn’t ever overlook or ignore the undertaking construction. They need to make investments extra time in studying in regards to the undertaking usually. In the event that they don’t do that, it may end in unhealthy outcomes in the long term. Subsequently, it’s important to have a well-organized undertaking framework. And with React Native improvement, the builders can aspire to combine good undertaking constructions.

Whereas these are solely 10, there is usually a collection of others as properly. As a developer, your final purpose must be to make as few errors as attainable.
