A brief journey of React Native

Journey of react native app development

React Native actually began as an internal summer hackathon project at Facebook in 2013. Then after two years in 2015, the first preview of React Native 1 was released. After the release in January 2015, Facebook officially launched React Native in March 2015 at the F8 conference.

The framework is older than Flutter and boasts a larger developer community as it is backed-up by Facebook. In addition, the social media platform giant is working on several other enhancement aspects of React Native. They are:

  • React Native fabric: This is a re-designed and architecture user interface layer
  • Lean Core: It assists in reducing the size of the mobile app. It does so my moving the features (movable) to different repositories
  • Turbo Modules: It is used to enhance the handling of the other native modules

With the backing of Facebook, React Native has a better and stable API as compared to its peers. Besides this, the framework focuses greatly on fixing any kind of underlying issues.

Important facts about React Native app development

React Native app development

There are some really astonishing facts about one of the leading cross-platform app development frameworks. This information is important and will make you understand the nuances of React Native in detail.

  • Mobile application development with React Native is done by using the same fundamental blocks. These UI blocks are the same for both Android and iOS.  Therefore, the developers don’t need to build blocks in Java, Swift or Kotlin separately
  • The widgets in React Native are analogous to the ones in Flutter

The tech world after the pandemic in 2020 has seen a paradigm shift. Thus in 2021, it has become even more important to know everything about a framework before opting for it. Therefore, now we will see the merits and demerits of React Native app development in detail.

Advantages of React Native app development

The perks of working with React Native for mobile app development are immense and staggering. It certainly provides the cushion to innovate to the developers as well. Below we have listed some of the top rated advantages of React Native app development. Let us have a look:

Advantages of react native app development

Ensure stable mobile app growth

The realm of mobile app development is highly dynamic as well as highly unstable as well. One of the greatest perks of using React Native for mobile apps is that it ensures a stable growth. Because the components of the framework know the art of displaying the app on the platform.

Moreover, this abstraction allows the developers to focus on app development rather than thinking about other details. Thus, the features of the app are more resistive to all the discrepancies and are consistent. Because of the resistance the hybrid apps give similar experience as the native apps.

Since everyone is on the same page during the app development process, the entire development is synchronized. The marketing team can skillfully plan the release of the app so that it could get the maximum attraction. Stability also increases the chance of better feature upgrades in the future.

Code reuse and pre-developed components

Code reuse and pre-developed components

Code reusability is another great advantage of React Native app development. In the React Native applications, the developers have the luxury to write the code once and use it many times. Because of this, the developers don’t need to write separate codes for different platforms.

This unique feature allows the developers to reuse almost 90% of the codes on both the OS platforms. Therefore, along with saving time, curtails the time taken to develop a mobile app. What’s even more interesting is that the code reusability is not restricted to just mobile apps. The developers can use them for website development as well.

Moreover, React Native mobile apps are faster as they have a set of pre-developed components. As it has an open-source library, it becomes easier for the developers to write the codes in advance. And these pre-written codes can be used easily as and when required.

Live and Hot reloading

Around the mobile app development realm, React Native is famous for this feature. Live and Hot reloading are the features that make React Native distinct. Moreover, you don’t get confused by the name, they are both different.

The Hot Reloading feature is simply based on the Hot Module Replacement (HMR). Moreover, it is based on the inception after the first reloading process. The HMR is nothing but an inter-mediator. It helps in updating the files and keeping them at a certain place while the app is functioning. Thus, React Native mobile apps can handle multiple tasks easily.

In addition, with Hot Reloading, the developers can see the changes they make in real time. Thus, in order to see a modification, they don’t have app recompilation. Also, Hot Reloading decreases the waiting time on the app.

On the other hand, Live Reloading is a tool used for compiling and reading the file. This process takes place where there are changes made by the developer. Moreover, it also offers a new file to the simulator. Through this file, the simulator automatically reads the app from the beginning.

Ready-made solutions and a vibrant library

React Native has a myriad of ready-made solutions that help in enhancing the mobile app development process. As for instance, the framework has a testing library that enables the developers to write bug-free code. Flawless coding helps in enhancing the credibility of the end product.

Some of the most versatile testing tools are:

  • Chai
  • Mocha
  • Jest
  • Enzyme

In addition to testing, if the developers wish to see successful type checking, there are tools for that as well. Tools such as prototype and Flow, ESLint, Axios, etc. are used for type checking.

Larger Developer community

Since React Native has the backing of Facebook, it is bound to have a larger developers’ community. Moreover, as it is an open-source platform, the technology is available for free for everyone. One of the greatest advantages of mobile app development with React Native is that it is using community-driven technology.

Moreover, an open-source platform also helps in recognition for writing codes. The developers can use the platform to create their portfolios, share their experiences, etc. This engagement will inspire them to write better codes with time.

The community driven technology will not let any developer walk alone. They can connect with other developers if they face any difficulty in React Native development.

Saves a fortune on application development

Since the developers can reuse the codes, React Native saves a fortune for your business. Thus, unlike native development, you can work with smaller teams and at the same time expand your app extensively.

Moreover, having one programming language has the perks of its own. It completely eliminates the glitches that disturbs the development between two platforms. Thus, it helps in maintaining clear communication between the team during the course of app development.

Thus, React mobile applications get ready on time on a regular basis. Besides, in case of React Native there is no down time. Thus, the developers can switch between platforms according to their needs.

Disadvantages of React Native app development

Along with all the high flying perks, React Native app development has its own set of challenges as well. Thus, as a business firm, you need to take account of them as well. For your benefit we have listed some of the highlighted demerits of React Native. Let us have a look:

Disadvantages of React Native app development

Very difficult to debug

React Native mobile applications are very hard to debug. As they are built using Java, C/C++, JavaScript, etc. the process of debugging becomes very tedious. Thus, the developers should have the knowledge of the Native language of the platform. Because, React Native constantly goes to and fro between the thread of JavaScript and Native environment.

To overcome this issue, the developers have enabled the integration with Flipper. It has a set of tools which can help in the debugging process.

Hard to determine user interface

If your mobile app requires many screen transitions, animation, interactions, etc. React Native app development is not for you. Mobile apps with complex gestures are not built using React Native.

Although there is a solution to this problem. React Native has a gesture responder system. It will run the entire lifecycle of all the gestures in the mobile applications. But when it comes to complex ones, the developers will still face some difficulties. This is because iOS and Android touch subsystems have a unified API and they are different from each other.

The framework is immature

The advances in React Native app development are happening every week. Every new release or update has a lot of changes and it takes a toll on the developers. The developers do not get adequate time to adjust to the changes and before they do that, they have to deal with another one.

Moreover, there are instances where the developers cannot write codes only for React Native. Because, they are required to write additional codes for components that are incompatible.

React Native is in every sense faster and newer. But in that quest, the framework tends to lose its credibility and becomes too immature for Android and iOS. Moreover, the flexibility of the React mobile applications are below par as compared to Native apps.

The curious case of JavaScript

There is no doubt about the fact that JavaScript is a powerful and flexible programming language. But at the same time, it is a loosely typed language as well. Thus, there might be a case where engineers feel that there is no type safety. Thus, it becomes very difficult to scale the React Native mobile apps.

Thus, it becomes inevitable for the engineers to opt for other third-party integrations. The third-party tools can be Flow and TypeScript for the already existing infrastructure.

Tougher to build a cross-platform team

Cross-platform app

At its core, React Native is nothing but a cross-platform app development technology. Thus, the developers must have concrete knowledge of both web and native technologies. They must know how to work on JavaScript, project configuration, CI, UX guidelines, etc.

It is difficult to find developers who have an in-depth knowledge of both the world. Therefore, you should only opt for experienced cross-platform app development firms.
