Common Mistakes to Avoid While Developing React Native Apps
Some errors or mistakes have become quite common among developers working on applications build on React. These errors may result from oversight, pressure to meet a deadline, or lack of React / JavaScript experience. The demand that the developers obtain from React Native is not just the fact that the industry has evolved to a degree that it now contrasts Native and React Native design modes. Also driving the demand is the constant updates that advance the framework.
However, this demand can only go so far. Ultimately, developers will need to learn their way around the development process on a ground level. Especially on the front of understanding and avoiding errors in the creation of React native apps that can ruin the user experience and their skills.
In this post, we divided the article into parts to ease the process of getting used to the errors that occurred during React Native App Development and explained errors that developers often make while building React Apps. While we use React in this tutorial, it is easy to apply most of the techniques, which we are going to talk about here.
What Is This React Native and Why is it So Important?
React Native is a kind of framework that constructs a hierarchy of JavaScript code-building UI elements. It has a collection of components to create a mobile app with a native look and feel for both iOS and Android platforms. On the other hand, ReactJS is an open-source library for JavaScript to create user interfaces. Nevertheless, Facebook designs both React Native and ReactJS using the same principles of development, with the exception of designing interfaces.
Making use of this React Native framework, we can easily expect to render the UI for both platforms. An open-source system could be compatible in the near future with other systems such as Windows or tvOS. Because React Native components have counterpart rights, these components can be reused to create Android and iOS devices.
With the support of the plugin, you can either integrate React Native components into the current device software or also recycle the Cordova-based code. Nonetheless, Cordova and Ionic software must be used to create your current app. The Development of a react-based app is comparatively quick, efficient, and simple. REACT Native is a boon for developers as there they no to learn Java specific to Android or Swift specific to iOS.
React Native is UI-focused, which is capable of loading applications fast and presenting the apps to feel as smoother. There is one more reason why REACT Native framework has gained popularity in recent years and become a favorite of developers as this framework helps one-way cater to both iOS and Android platforms, which is favorable for mobile developers. Giant companies such as Snapchat, Amazon, Twitter, Skype, Airbnb, Tesla, UberEATS, and many more have now turned their eyeballs towards it.
The focus on a wide marketplace and profit is fulfilled by using the React Native Platform. Since the number of iOS users is lower than Android users and yet generates more profit, many industries are facing the dilemma of whether they should focus on making more profit by building iOS apps or building user strength through Android apps alone.
Why React Native is Developers Favorite?
Despite having few loopholes, Still React Native Most Effective Solution for App Development in 2020 and therefore the REACT Native Framework passes all tests and obstacles to become the number one option of virtually every ‘ React Native Development Company ‘ to create mobile apps.
- It Allows Quick and Quite Cost Effective
It is no secret that at lower efforts, any company goes for higher profits. For deployment on iOS and Android devices, a single application is used with React Native. By shortening the activity duration and scaling the team involved during a task, the business owner saves time and costs. It can save almost 50% of the development effort without losing either performance or productivity.
- It Provides Cross Platform Capabilities
It implies that a single platform effort— both iOS and Android — makes it possible to get the app for two platforms. Typically, this company will not suggest or use anything that is inferior, if not the best. The support for iOS was released in early 2015 and support for Android was released in the fall of the same year.
The architecture blends the benefits of mobile app development with the rapid development and optimized output environment of native reactions.
- React Native uses JavaScript
JavaScript is one of the languages with which a developer begins their career. Therefore, they are really close to the subject matter in general. Largely, the fact that React Native relies heavily on JavaScript brings down the curve of learning. React Native has strong support from a large developer community. If a problem arises, JS and native enthusiasts encourage quick repair, similar to sharing distinctive development skills and instruments required.
- Supports Third Party Plug-In And Better Memory Management
This eradicates the need for specific web View features throughout development with third-party plug-ins. It allows the plug-in to be linked through the framework to a native module. For smoother running, faster loading, and better memory management, these processes can be linked with app options.
- Provides Single Code Base For Both Android And iOS
This means that many mobile operating systems can be implemented with one code base. Elements can be reused to existing code at any level without rewriting it.
The framework is open-source compatible with various platforms and accessible to a large developer community. It helps you to write native modules using a very comparable language and compare it quite easily to the base of React Native code.
- Develop Hybrid Apps Which Perform As Good As Native Apps
React Native code building blocks are reusable native elements and can be compiled on native platforms. Therefore, during coding, it is not appropriate to use Web View system components. As a result, the apps also perform to look and feel like native apps with relevant functionality. This uses the graphics-processing unit, while CPU-intensive is used by native platforms. It provides better options for a fast and agile app development experience compared to other hybrid frameworks.
- They Get To Build Native Applications
Although the developers are working on JavaScript, they do not use the web view to render components from React Native. The one reason you should choose React Native is that it makes real native elements, giving developers the ability to use platform-specific components such as activity indicator, which gives a familiar, native-like feeling to every platform.
- The installation process is Simple and Straightforward
The method of installation must always be straightforward, i.e. minus any difficult steps. The React Native Framework can be built through the Node Pact Manager, which developers with JavaScript experience can obey extremely easily. In addition, even if you do not have JS understanding, React Native will prevent you from having trouble-downloading binary from the source.
- Greater Productivity
The key to building apps faster is the productivity levels of developers. Although JavaScript’s stability already makes the process easier, it also provides a live reload feature and the flexibility to use any IDE or text editor of your choosing.
- Conversion of Any Web Project To A Mobile App is Simple
Through React Native, the code can be easily reused and only basic updates are required for the versions of the two platforms. It makes it easier to find bugs within codebases. React Native’s interface is standard and intuitive. It implies that developers who are not involved in the project will simply know it and take it as a basis for starting to work on it. QA engineers are going to spend fewer hours studying programming logic and writing relevant test cases. All this helps you to save lots of time in a mobile decision to reshape the web venture.
- Community Backing is Very Strong
React Native has gained a lot of popularity since its launch in 2015. Developers and companies from all over the world and from an industrial background have opted to go with React Native at the back of the multitude of advantages it provides. In turn, this high demand resulted in a strong, widespread community working on a daily basis to adjust the React Native pros and cons.
Challenges Involved with React Native App Development
- Dependency On Native App Developers
Developers sometimes have to rely on native developers to understand how JavaScript works. Especially when you need to put in the application heavy computing operations. These types of apps force developers to download computation to the app’s native part, which requires a native developer to do so.
- Limitations in the Abstraction Layer
An abstraction layer is built on the native platform to provide more features to the React Native applications. The abstraction Layer itself comes with some recurring problems and issues to be avoided in the creation of React Native apps like:
- It is incredibly difficult to identify vulnerabilities that are found in the abstraction layer
- Heavy reliance on resources and libraries from third parties
- Rely on custom design implementation
- Absence Of Support For Multiprocessing Or Parallel Threading
React Native consists of a single JavaScript thread that allows developers to observe slow performance when they want to run any parallel processes.
- Deployment of iOS is Difficult
In the case of React Native, developers find it particularly frustrating when they want to test their iPhone app on any testing services in addition to Apple’s Test flight, especially as they will have to deal with issues of obtaining supply profiles and certificates that are required.
On iOS, however, the process is not very complicated, as testing and deploying Android apps is very smooth and hassle-free. The only difference between a professional and an unqualified React Native developer is the awareness of errors that should be avoided to produce a React Native error-free app.
Common React Native App Development Mistakes
- Wrong Redux Store Planning
As a designer, we focus more on designing the device design when we get an innovative project, and less on the data handling aspect of it. Redux helps to correctly store the data and control device states for debugging. It can be a powerful tool for managing device information when designed correctly. If not, many things can be messed up.
Another point not to be made when developing the Redux app is that it is not very suitable for small projects. Even minor changes will require you to write long lines of code. So, when choosing React Native for startups, it will be better if you choose to go with it for large-scale applications and avoid it.
- Writing Logic In Components
The pattern of presentational and container element design is often one of the first to appear while looking for a proper way to create components for reusability. A common mistake that you will see in React applications is that one element fuses the design markup and the device logic. The downside of this approach is that without copying and pasting, you cannot easily reuse any of the components or logic.
- Not Reading External Modules Codes
Saving time with external modules is not unusual for developers. It makes things easier and quicker, especially when they come with documentation. Most often, however, modules break or may not function as planned. That is why developers should read the code and view the move as one of the best practices of React Native. Doing this allows you to know what is wrong with the system and how to fix it.
- Not Writing Unit Tests
This is one of the most common mistakes out there. It is often overlooked because without unit testing applications can still work technically. A unit test enables you to independently test parts of your application to ensure that certain functionality works as expected.
You might wonder why you were going to write such a small test. Often, after writing your components, you expect your prop to appear properly, but sometimes it may be blocked by a contrasting CSS template. Writing a unit test saves you time by pointing it out immediately (failing) to track that bug. They allow you to test your software quickly.
- Left console.log Statements
The statements of the console log are very handy and help monitor the execution of the device. However, when you leave the log statements in the app, what happens?
Unless you keep the rendering methods and logic inside, particularly those that are asynchronous because they can lead to a bottleneck in the JavaScript thread, this can turn out to be a serious issue. All of this ultimately leads to a smoother process.
- Making Use Of Stateless Component For Gaining React Native Performance
Some developers still believe that it is true even now, what was true before React 16. The stateless module means that no category is expanded by the component. It essentially takes the argument in the DOM as display and props. It comes with benefits like –
- Easy testing ability
- Fast implementation
- Does not use state or the local variables
- Not optimizing React Native Images
It should be a high priority to optimize images in apps built with React Native. This helps resize the images locally and then upload them to server-based cloud storage such as the s3 and get the CDN connection that can then be returned using the API.
