React Native for engineers – How is it helpful?

React Native is an open-source JavaScript framework that is designed for building apps on numerous platforms like iOS, Android, and also web applications that uses very same code base. It is based on React, and further brings all its glory to mobile app development.

React Native was basically a Hackathon project that aims to solve the company’s biggest pain point - maintaining two code bases for their app. The problem with maintaining two code bases for such a big app is work duplication and, solving the same problem in two different ways.

React Native uses JavaScript by the students of best engineering college in Jaipur to compile the app’s user interface, but using native-OS views. For more complex features, it enables code implementation in OS-native languages.

How Does React Native Work?

React Native uses JavaScript to produce the interface of an application. Unlike its competitors, React Native does not rely on web views, but the actual real materials provided by native platforms. It has built-in access to the native components and views, and further utilizes native-written code and allow the API access to OS-specific features inside the app.

React Native uses the concept of “bridge”, which enables asynchronous communication between the JavaScript and Native elements. It is the bridge concept lies at the very heart of React Native’s flexibility. Native and JavaScript elements are different technologies, but they are able to communicate.

This type of architecture offers the benefit of using a lot of OS-native features to the students of top engineering college in Jaipur along with some important challenges. For instance, constant use of bridges inside the app must slow down its performance. While building an app that involves many events, a lot of data, etc. React Native might not be the perfect option.

Benefits Of Using React Native

1. Code reusability & faster development

The effective development for numerous platforms at once is the biggest and strongest advantage of React Native. Utilizing the same code base for variant platforms carries other benefits like faster development and time-to-market of your app, easier and cheaper maintenance along with a smoother onboarding process for new developers joining the project.

React Native allow developers to see the changes in the code in a live preview, without the need to refresh anything. This small tweak can actually tangibly improve the development process as it provides real-time feedback to anything that has been altered inside the code. 

2. Performance

Compared to other cross-platform development solutions, the “bridge” concept of React Native can be seen as revolutionary. The official claim is that React Native provides “native-like” performance, but it is not necessarily the best way to put it is that it gives “near-native” experience to the students of engineering colleges Jaipur.

3. Cost efficiency

Cost efficiency is the basic reason for cross-platform development. This is due to reusing code on multiple platforms, you usually need a smaller team to deliver the project. As opposed to native development where an individual need two separate teams to deliver basically two similar operating products instead of one.

4. Growing developer community

React Native is an open-source framework, that is thriving and constantly expanding. They are constantly working on elements and improvements widening the framework. While encountering a problem that has not yet been solved in React Native you might find a bunch of people eager to help you out as they are concerned with making the framework more stable and comprehensive.

Drawback Of React Native

1. A relatively young technology

React Native is still relatively new, and definitely has some limitations, glitches, and issues requiring to be addressed. Some custom modules do not exist in the framework, as developers might need more time to build and create their own new ones from scratch. Your partner company or your developers should allow you know about this during the app estimation process.

2. Need for native mobile developers

The asset of React Native implements native code for better performance means that at times React Native developers might find themselves in need of help from native mobile app experts. Similarly, it works in the AppStore and Google Play Store. Typically, native mobile developers of best BTech colleges in Jaipur are more familiar with the procedure and necessary documentation for a successful launch.

3. Does not go well with complex designs & interactions

The performance of React Native pales when confronted with complicated UI design decisions, complex animations, and heavy interactions. This is because of the bridge concept that all native modules have to communicate with the JavaScript part of the app, and too many interactions may slow down the app significantly, making it laggy and simply giving a bad experience.

4. Reliance on Facebook

Relying on a third-party open-source technology has its drawbacks on its own. If Facebook decides to step down from using the technology, it might force others to move back from it. Today, Facebook utilizes React Native in their main Facebook app, Facebook Analytics, the Ads Manager app, and Instagram. The community of framework is constantly expanding and new big companies are jumping into the game.

Conclusion

React Native is an excellent framework that allow students of top BTech colleges in Jaipur to create robust mobile applications using their existing JavaScript knowledge. It offers faster mobile development, and efficient code sharing across Android, iOS, and the Web, without sacrificing the end user’s experience or application quality. It is new, and still a work in progress.
