Pros and Cons of React Native Development in 2021

To achieve success in the web industry, it is essential to keep up with modern technology. You can use JavaScript to develop mobile applications with react native, also known as RN. In most cases, Java is used to develop an Android mobile app, while Swift or Object-C is used to develop an iOS app. You can use React Native to create mobile apps that work well on both platforms.

What is React Native?

React Native is an open-source User Interface software framework developed by Facebook, Inc; Initial released in 2015 March. It is used to create apps for iOS, macOS, tvOS, Android, Android TV, Windows, Web, and UWP by allowing developers to use the React framework along with native platform capabilities.

Facebook created an additional API that simplifies interaction with both native APIs and enables them to develop applications for both Apple (iOS) and Google (Android) platforms using a single code base rather than two. That is why it is referred to as “cross-platform.”

Pros of React Native

We can now explore React Native’s pros and cons. The key pros of React Native are given below:

Code reusability: Developers enjoy React because it allows them to reuse and recycle components they’ve previously created. The cool thing is that you can use the web app code (written in React) to create mobile apps.

One of the biggest benefits of using React Native is that you can write most of your mobile code in JavaScript. By simply sharing logic across the web and mobile versions of an application, you may eliminate a lot of duplicate code.

Fast refresh: Fast refresh enables developers to run the app while updating it to new versions and modifying the UI. The changes are immediately visible, and the developer is saved from rebuilding the entire app.

Simplified UI: React Native is strongly based on the creation of a mobile user interface. You will need to create a sequence of actions in the application during native development. Easier to spot bugs on the paths a user can take.

Reliable: You can put React Native on your list of tried and trusted frameworks. The framework is used by Facebook, Instagram, and Uber Eats, among others.

Cost efficiency: The ability to reuse code and components is the most significant cost-cutting feature of React Native. This framework enables developers to write code once and share 90-99% of it between iOS and Android platforms without any technical issues.

Cons of React Native

Not a Native Solution: Framework writers must typically create a connection/communication method between Native and React Native, as well as JavaScript. As a result of this process, React native applications are slower than native apps and may even take up more space. This issue is most common in applications with a lot of dynamism.

React Native is difficult to debug because it is built with JavaScript, Objective-C, Java, and C/C++. It’s not easy to troubleshoot. Because React Native is constantly connected to the native environment, some basic knowledge of the native language is required. The React Native community had to provide additional software to facilitate debugging.

Building a Cross-Platform Team is More Difficult: Because the team must be familiar with both technology worlds, it is much more difficult to assemble a team capable of dealing with the issues that arise during the development of the app.

Examples of apps built with React Native

  • Facebook
  • Skype
  • Instagram
  • Pinterest
  • Baidu


However, React Native app development companies should be chosen because they can develop Android and iOS systems and are based on a custom design. This fact in and of itself provides numerous advantages at various stages of development. RN’s custom design also allows for easier and better styling across platforms; while the pros and cons can be weighed and decided against, RN is a solid and almost unrivaled system.
