React Native development: Pros and cons in 2021

React Native is a well-known framework for creating mobile apps. It’s cross-platform, attractive, popular, and appears to save time and money. Some even believe it is on the verge of displacing native development as the dominating mode of development.

The major advantages and disadvantages of React Native app development are discussed in this article. It’s worth considering them before determining whether or not to build a mobile app with React Native.

What is react native?

React Native, a Facebook-created open-source framework written in JavaScript. It allows the creation of Android and iOS mobile apps. They can work on any device while maintaining a single codebase.

RN is an ideal solution for reducing development expenses while maintaining native speed and user-experience flexibility.

Let’s look at the advantages and disadvantages of React Native and discover what it offers. 

Pros of react native development 

Faster app development process

The biggest benefit of React Native is that it allows you to construct apps for two platforms with only one line of code. As a result, while working on a certain function/update, we develop them for each mobile platform right away.

React is popular among developers because it allows them to reuse and recycle previously generated components and the rest of the React Native ecosystem. They may also share their codebase, allowing them to work more quickly.

Less app development cost

Since the source code is shared, the app is built by a single development team that is familiar with Javascript. This makes a major difference in terms of lowering app development costs.

Having a single team and a single programming language also makes it easier to solve difficulties that arise when work between platforms is interrupted. 

Code reusability

You may reuse the codebase between iOS and Android with React Native. True cross-platform development is possible to some extent, depending on how many native modules you use in your application.

You may use JavaScript to share your codebase not just across mobile devices, but also between other React web apps. Tools like React Native Web are actively being developed in this regard.

Simplified User interface (UI)

The core of React Native is the creation of a mobile user interface. You’ll need to define a sequence of actions in the app while developing natively. Declarative programming is used by RN, therefore such a sequence of activities is no longer necessary. As a consequence, spotting issues on the pathways a user can take is considerably easier.

Cons of react native development 

Debugging is difficult

Javascript, Objective-C, Java, and C / C ++ are used to create React Native. Debugging bugs becomes more difficult as a result of this. React Native interacts frequently between the native environment and the thread in which the Javascript code is performed, hence it may need a basic understanding of the platform’s native language.

Building a cross-platform team is more difficult

React Native is a framework technology. The team should also be familiar with web technologies (React, JavaScript, and its ecosystem) as well as native technologies (project configuration, CI, UX guidelines for the platform). Building a team capable of dealing with all of the issues that arise during cross-platform application development is significantly more challenging.

When to choose to react native development? 

Choose react native if:

  • you want to build the application for both Android and iOS 
  • you do NOT require creating complex animations
  • if you have a web application (especially one created in ReactJS) that performs the same functions as the target mobile app
  • You want to build an application lowering the cost of development
