What’s fascinating about React Native is that allows mobile app developers to leverage React’s framework combined with native platform features and so lets them design applications that look and feel native.
Many firms throughout the world, including Facebook, Uber, and Skype, have embraced the framework, which has received widespread support from the community as a result of its popularity. This framework is, without a doubt, a great tool for developing high-quality, scalable applications.
However, even though React Native has acquired widespread recognition and has attracted the attention of mobile app development businesses throughout the globe, developers often encounter difficulties and make errors while developing react native applications.
This article will be entirely focused on React Native common errors to avoid while creating a React Native app. But before everything else, let us see the features and drawbacks of React Native for getting you familiar with its structure!
Features Of React Native
Before moving ahead with React Native app mistake, we will look into the features provided by React Native:
Write Once Use Everywhere
Apps written in React Native focuses on cross-platform support. By far the most useful aspect, as well as the fundamental notion on which it is founded, is that code written in React Native will run on practically any mobile device available. It covers operating systems like iOS, Android, and Windows.
No need to develop code in Swift for IOS, Java for Android, or C# for Windows; we can use our existing code. The apps created using React native are native, which means that they may be run on a variety of systems.
The programming language used by a framework is an essential component that has a significant impact on the developers. If a framework makes use of a programming language that is popular and extensively used, it will always have an impact on the decision of a developer who will utilise the framework.
React Native is only concerned with user interface design. It has excellent responsiveness, and its rendering capabilities are among the finest available.
Great Community Support
When it comes to community, the React Native community is one of the most active and supportive in the cross-platform mobile application development industry. The development of React.js began in 2013 with Facebook, and it was officially released in 2015. Soon after, it was made open-source, and its popularity grew at an exponential rate.
Its popularity was boosted even further by the developers who contributed from all over the globe, resulting in a large and active community presence.
When it comes to cross-platform application development, the React Native framework is one of the most trustworthy frameworks available. It has been tried and tested enough to be trusted by an IT behemoth like Facebook.
All of Facebook’s mobile apps are built using React Native. This is sufficient reason to put your faith in React Native. Furthermore, it is utilised by a variety of other businesses, including Instagram, Airbnb, Skype, Tesla, Walmart, and Discord.
Lesser Development Time
The development time required for React Native is significantly reduced.
Supports third-Party Libraries
One major difference between Flutter and React Native is that the latter make use of extensive third-party libraries! The use of third-party libraries is always positive in terms of efficiency and effectiveness. The developers will have more flexibility of choice as a result of this. This is both a blessing and a curse at the same time.
Limitations Of React Native
Now, we will see the limitations of React Native before moving ahead with React Native app mistake:
- React Native is just utilised for rendering reasons and is not used for anything else. Third-party libraries are strongly reliant on for this to work. This is both a blessing and a curse at the same time. A developer has the opportunity to pick which third-party libraries to use, but doing so may also be a source of frustration.
- It does not provide a large number of testing choices. Initial unit testing alternatives are limited, but when it comes to integration and user interface testing, there are no formal tools available. In any case, there are third-party technologies available, such as Appium and Detox, that might be used for testing.
- The documentation for React Native is out of date and not updated often. There isn’t a lot of information provided in the manual. Even the process of installing and configuring the software is not well described. There is also no official documentation for Continuous Integration and Continuous Delivery (CI/CD), which is a major disadvantage.
- React Native is usually simple to learn for folks who come from a React or web development experience. However, for newcomers, React Native might be confusing and difficult to understand.
This was a brief introduction to React Native advantages and limitations. Now we will see the major React Native app mistake to avoid while building a React Native app.
React Native App Mistake
You already know how to build React Native app. But how do you avoid the major React Native app mistake during the development phase? These are the major mistakes to avoid in React Native project structure:
Image Optimization In A Dispropriate Aspect Ratio
When it comes to application development, image optimization is the most critical phase to complete. Despite this, a huge proportion of app development teams choose to neglect this procedure. Because of this lack of knowledge, there is a great likelihood of receiving photos that are misaligned in the end output.
Image optimization has a significant impact on the load speed of photos on your website or mobile application. Furthermore, optimization will assist you with downsizing the photographs locally, following which you will be able to upload them straight to cloud storage services.
As a result, in addition to ensuring that photos are synced, image optimization facilitates the upload of photographs to cloud storage services. Proper picture optimization makes the overall programme more lightweight, which improves its speed and scalability while decreasing its size. As a result, if you want to create a fully functional app, you should avoid making this React Native app development error.
Misaligned Redux Store Planning
This is a major mistake while building a React Native app. Every new project requires a developer to concentrate on bringing something fresh to the table. However, when you spend more time planning the app interface and less time planning the data processing, you are more likely to make errors.
Because it aids in the proper storage of the data, competent redux store planning is essential for success. Additionally, it debugs the app rates and manages the data for the user. As a result, if you make a mistake with the redux shop planning, you will be digging your own grave.
Furthermore, if you are working on a small project, you should avoid the redux store planning process as much as possible. Because developers must write long lines of code in order to make minor modifications. Because of this, redux store planning is more appropriate for large-scale applications.
Paying Insufficient Attention To Details
Paying attention to details is one of the React Native best practices. One of the most common faults in React Native is an inaccurate estimate. Yes, a lot of reusable components will be made accessible to developers, but the layouts for iOS and Android are rather different. Furthermore, the layout of the page might be totally different for both iOS and Android users, depending on the device.
As a result, it is unavoidable that the developers pay close attention to the specifics or risk losing a lot of money. In their drive to save time, developers should avoid the use of external modules as much as possible. Because they may not be able to read the codes that have been taken from the modules if they proceed in this manner.
In the long term, this practice of disobeying the rules might lead to major problems for the organisation. Furthermore, by interfering with the current codes, the inclusion of extra modules might impair the operation of the existing codes. Consequently, developers must avoid making this React Native app development error and must pay close attention to the details throughout the process.
Encouraging Stateless Components In Code
Change is the one constant in life, and those who do not accept this are doomed to extinction. Furthermore, developers who believe that everything that was true before the release of the React16 library is still true after the release of the library are greatly erroneous.
As a result, they are more likely to employ stateless components. In addition to using stateless components, developers have a tendency to commence the stay in the incorrect manner. In layman’s terms, stateless components are those that do not extend any form of class or interface.
As a result, instead of using them, developers should focus on developing pure components for React Native applications. Because with pure components, the process of re-rendering occurs only when a change in the states is noticed, this is a good thing. Otherwise, re-rendering occurs in proportion to the size of the parent component in a stateless component.
In addition, by performing AJAX queries within componentDidmount, the developers may do a variety of additional DOM actions on the fly.
Avoiding Unit Test
Avoiding unit tests is a grave mistake while you build a React Native app. Yes, pushing on without a well-defined unit test may land you in hot water quickly and dramatically. This is due to the fact that addressing defects after a product is ready for launch needs a significant amount of time and effort.
Furthermore, if you do not make any changes to the product, the final output will have flaws as well. Writing unit tests will help to limit the amount of unneeded drama that occurs when the programme is first launched. Furthermore, in addition to streamlining the app creation process, it helps to improve the overall reputation of your app.
It will be possible for the developers to access various areas of the applications independently if they use well-documented unit tests. As a result, constantly test each and every component at the appropriate stage to assure trouble-free operation. Additionally, establishing a unit test can relieve your developers of any extra stress that may arise throughout the app development process.
It is usually recommended that developers avoid enabling log statements to be used inside the programme itself. Despite the fact that the console log statements assist in the debugging process of the application and are relatively simple, they are still useful. Nevertheless, if the developers continue to employ unsynchronized rendering logic, this might result in difficulties.
As a result, while designing React Native applications, developers must exercise caution when using log statements. They must ensure that the log statements are not left in the programme.
Change Of State Inside Render Function
The following is a visual depiction of the View and the Datastore, respectively. In contrast to the view, which is time-based, all information included inside the component is saved in the data store. Following that, the datastore takes further data from the set before displaying it on the screen for the user.
There is a setState() method in React Native that takes a fresh new object and compares it to the past states of the object in question. Following the merger of the preceding state, a new state is created. After that, information is delivered to the datastore for storage. It is possible to perform this cycle at any moment throughout the component’s lifespan.
The sole requirement is that the app must be developed in React Native, and this is the only restriction. Direct mutation, on the other hand, has the effect of interfering with the component’s whole lifespan. The disrupted lifecycle causes the prior states to become corrupted as well.
As a result, the mobile application performs in an odd manner, and it has the potential to crash completely. As a result, directly altering the state of the programme might potentially shorten its overall lifespan (see below). There is also the possibility that you, as an application developer, might lose track of all the prior states of the application.
As a result of this React Native app development blunder, you may find yourself writing bespoke code. When the modification of states occurs in a direct manner, these scripts are used in lieu of React. Extra codes will make the software heavier and will lengthen the time it takes to load.
Failure To Establish The Adhered Norms
If you do not follow the fundamental principles of React Native app development, you may find yourself in serious trouble. As a result, developers and designers must constantly adhere to industry best practices.
The React Native development framework includes a comprehensive collection of recommended coding practices that developers are required to adhere to. Consider the fact that developers must adhere to naming standards in order to improve the readability of their code.
Furthermore, deviating from traditional development practices would impede the entire development process in general. As a result, developers and designers must constantly adhere to and adhere to established standards and guidelines.
Ignoring Project’s Organisational Structure
It is a well-known truth that big apps have a massively complicated structure that may be difficult to navigate. In addition, the incorrect layout will make it difficult to keep the project up to date and running smoothly. The developers should be aware that there are a plethora of options on how to organise a project on React Native app structure.
Thus, they must never lose sight of or neglect the project’s organisational structure. A well-organized set of files and folders makes life much simpler for everyone involved, including the developers and graphic designers.
As is customary for developers working on React Native applications, they do not spend much time learning about the project prior to starting work. They are making a tremendous error here, and the consequences will be disastrous in the long term.
As a result, having a robust and well-organized project structure is critical to success. Furthermore, using React Native development, developers may aim to include sound project frameworks into their work.
Wrong Estimation Of Project
It is possible that several layouts will be used in conjunction with a number of reusable components. In fact, the very structure of an application page on iOS and Android might be very different from one another. You should also provide an estimate for the validation layout.
When developing a React Native application, you can expect to write more code than when developing a Hybrid application using, for example, Cordova or Angular. When developing a Web application, it is important to examine all of the various endpoints that the backend has to offer.
Furthermore, since you will be responsible for handling the logic in the application, it should all be written appropriately. You should be familiar with the database structure, including how the entities are linked together.
Avoid React Native App Mistake To Avoid
React Native development has all of the components necessary to become the top framework accessible, if not the greatest framework available. The only snag here is that the developers must avoid making any of the given common React Native app mistake.
Market heavyweights such as Skype, Instagram, Bloomberg, Facebook, and others have chosen React Native app development as their platform of choice. As a result, if you can eliminate all of the harmful practices and keep your blunders under control, React Native may help you become the greatest in your field.
