React Native is undoubtedly one of the most widely used cross-platform frameworks for creating native-like apps. This framework can be easily used for developing brand-new apps from scratch and even in existing iOS or Android projects. So, it is immensely popular and loved by beginners as well as experienced developers. Consequently, the demand for the development of React Native apps is on the rise. Here are the top benefits it offers to one and all.
Foremost Advantages of using React Native for app Creation
- Code re-usability for a speedy development process
- Pre-built components and third-party plugins to create feature-packed good-quality apps from scratch
- Creation of performance-based apps with higher reliability and stability
- Technical goodies like modular architecture, declarative coding style, and ‘hot-reload’ feature to enhance the productivity of React Native app developers
- Rich and friendly UI/UX design
- Powerful and knowledgeable community to support
- An easy and direct installation method
- Faster time-to-market
- Creates solutions that allow adaptation to Android and iOS along with smart TVs, VR devices, etc., since it is a cross-platform framework
With so many outstanding advantages to offer, this framework has a bright future. But like any other framework, there are several challenges or limitations that are inherently associated with developing apps using React Native. Here we have outlined a few of them.
Probable Challenges in the React Native App Creation Process
One of the challenges in this framework is the dependency on native app developers, especially while dealing with complex and heavy computational processes. Another challenge, rather limitation, is that this framework does not support parallel threading or multiprocessing. So the performance of the apps slows down while executing multiple processes simultaneously.
Also, the abstraction layers in React Native have certain limitations. They have a dependency on third-party services and libraries. Finding bugs in abstraction layers is quite difficult; hence resolving them too is time-consuming. Another challenge while using this framework is faced during iOS deployment since testing the iPhone apps on any other testing service except Apple’s TestFlight is quite annoying.
Despite these challenges, React Native is a preferred choice of mobile application development agencies for writing robust and natively rendered applications. Moreover, these challenges can be handled well by experienced developers, whereas, a beginner or an unskilled developer tends to make more mistakes.
So, for the development of a flawless end-product, react native developers, particularly the newbies, must have prior knowledge about these probable errors. Let us have a glimpse of the commonest Development mistakes concerning React Native that could be avoided while building apps using React Native.
React Native App Creation Mistakes to Avoid
Improper image optimization
Image optimization, despite being a crucial step in app development, is commonly ignored by developers. But optimizing the images is necessary for reducing the load time of images. It helps in resizing the images locally and then allows uploading them automatically on the cloud storage like Amazon S3 by the server. After this, the developers get a CDN link that can be returned through the API. This entire process makes the app lightweight and boosts app performance.
Presence of console log statements
Inappropriate Redux store planning
Redux is quite useful in React Native for managing the apps effectively, handling and storing the gathered data correctly, debugging app states, etc. But Redux must be planned well for utilizing it to the fullest, or it may lead to issues, especially in small projects. This is so because Redux demands writing long codes even for the smallest of modifications. So, it isn’t suited much for small-scale projects but is a good choice for larger apps and projects.
Inaccurate or wrong project estimation
The chances of committing mistakes while estimating for project in React Native are higher for various reasons as given below:
- The layouts and structures of app pages for iOS and Android are different. Also, several common components can be interchangeably used for development but the design of the app in most cases will not be alike. As a result, estimation for both platforms can be different.
- The code to be written in React Native is usually larger as compared to the code required in the development of a Hybrid app on Cordova. In such cases, the assessment of the validation layout also must be considered.
- All the endpoints offered by the backend must be checked. Other vitals like understanding the data structure, connecting the entities, handling the logic, etc. must be considered during estimating the project.
If the developers handling the React Native framework are not aware of these differences, they can estimate incorrect dates for project completion, leading to hassle in the later stages.
Utilization of stateless components
A stateless component means that the components don’t extend any class. These always render the same thing and print out only what is provided to them through props. These are also known as dumb components. But, stateless components can be implemented faster, reduce the amount of boilerplate code to be written, and enable easy testing. In the app creation process, it is advisable to use pure components instead of stateless components. This is so because, for stateless components, rendering happens after the re-rendering of the parent component. But for pure components, re-rendering takes place when a change is detected in the states or props.
Not verifying external module codes
The app developers working with React Native commonly use external modules as this makes the development faster and easier and thus, saves time. But these modules may not work as expected or even break at times. Hence, the developers must read and verify external module codes before using them.
Not considering unit testing
One of the most common mistakes developers can commit while crafting apps using React Native is not writing a unit test. The apps can still function irrespective of whether unit tests are conducted or not, but such apps may not provide a great experience to the users and could be less competent in the market. Unit testing enables assessing different parts and functionalities of the apps and ensure they work as expected. It also helps to detect bugs in advance and make sure that the app segments run independently.
React Native has the potential to become “The Best” framework amongst all the available frameworks in the market. It is already being used by big players like Facebook, Delivery.com, UberEats, Bloomberg, Skype, Instagram, Tesla, and many more. It has some downsides as well, but those can be minimized to a great extent if every React Native app development firm trains its developers on diligently handling the common mistakes well in advance.
