Pros And Cons of React Native Development in 2022

One of the most popular open-source frameworks, React Native, allows developers to design apps in JavaScript and display them with native UI components. As a result, a larger amount of the codebase, mainly for Android and iOS, may be shared across platforms.

We may create a native application for Android and iOS frameworks by maintaining contact with one code in Javascript.  Following the development of the application, we receive a comparable record as if we had used the platform’s native language. You should hire a react native developer right now if you want to expand your business with the help of a mobile app.

Let’s look at the benefits and drawbacks of react native development:

Pros of react native development 

What are the advantages of React Native? The decision to build a mobile app utilizing the cross-platform React Native framework has a number of benefits. I’ve listed the most compelling advantages of utilizing React Native below.

Faster development 

The ability to create programmes for two platforms using the same code is the key benefit. As a result, when working on a certain capacity/update, we produce them promptly for all mobile platforms. This can save you up to 30% on time and money when an item is delivered on both platforms.


Developers must create distinct codebases for iOS and Android in native app development. As a result, native Android and iOS teams work on the same project at different rates and with different techniques, resulting in inconsistencies. Furthermore, in the case of native languages, Android and iOS developers are unable to swap platforms. The overall cost of application development rises as a result of this.

To write the project on many platforms, however, React Native requires just one team of iOS and Android or JavaScript engineers. And, if a project-specific developer is unavailable, any other developer can continue working on the left project. This boosts the app’s versatility, allowing it to be updated and upgraded more easily. Furthermore, the majority of the code may be reused, lowering the overall cost.

Fast Refresh

The React Native team appears to be paying close attention to what the community has to say. The Hot Reload functionality was one of the most frustrating aspects of React Native. It was turned off by the majority of developers since it was unreliable. Fast Refresh is the solution to these issues. This solution, which was introduced at the end of 2019, addresses all of Hot Reloading’s difficulties while also providing a wonderful developer experience that speeds up the development of new features and bug fixes.

Fast applications

Many people believe that React Native code can slow down an app’s speed. Although JavaScript isn’t as quick as native code, you won’t notice the difference in most circumstances.

We put a small application created in React Native and Swift to the test and compared the two versions. The performance of both applications was quite identical. Performance differences were minor, nearly imperceptible to the ordinary user. The framework may be less efficient in more complicated applications, but you can easily migrate some code to a native module and it won’t be an issue.

Code reusability

Reusability of code is another significant benefit of React Native mobile app development. Developers have the advantage of developing code once and reusing it several times. The code reusability feature helps developers save time by eliminating the need to write distinct scripts for multiple platforms.

On both OS systems, React Native app developers reuse about 90% of the code. Even more intriguing is the fact that code reuse is not limited to mobile apps. They may also be used for website construction by the developers.

Hot reloading 

The react native app developers may view the changes they make in real time thanks to hot reloading. The finest aspect about this important function, without a doubt, is that it reduces the time spent waiting on the app.

Live reloading, on the other hand, is a tool for building and reading the file. This procedure occurs when the developer makes modifications to the code. It also provides the simulator with a new file. The simulator reads the app from the beginning with the help of this file.

Provides a Stable Release

Developers are always on the lookout for a stable framework that can readily address faults while also avoiding breaking updates. Breaking changes in mobile app development might lead other components to fail.

With React Native, however, this is not the case. When React Native first started providing regular release updates, it presented problems for developers who didn’t want to upgrade their apps.

A major development base

React Native is an open-source JavaScript platform that allows developers to contribute their expertise to the development of the framework, which is available to everyone. If a developer runs into a difficulty, they can seek help from the community. There will always be someone who can assist them in resolving their problems, which helps them improve their coding abilities.

Cons of react native development 

What challenges do developers and app owners experience when using React Native? Using React Native has a number of drawbacks and challenges, in addition to its undeniable advantages. You should think about these while choosing this technology for your application.

Issues with compatibility and debugging

While this may come as a surprise given the fact that leading IT companies employ React Native, it is currently in beta. Your programmers may run into problems with package compatibility or debugging tools. If your developers aren’t React Native experts, this might slow down your development as they spend time troubleshooting.

Building a cross-platform team is more difficult

React Native is, at its heart, a cross-platform app development framework. Developers must be well-versed in both web and native technologies to be successful. They should be able to deal with JavaScript, project setup, continuous integration, and UX principles, among other things. It is becoming increasingly difficult to find developers with in-depth knowledge of both, making it critical for you to hire an experienced app development business.

The user interface is difficult to figure out

If your mobile app demands capabilities like numerous screen transitions, animations, and interactions, React Native may not be the best option for you. React Native is not used to create mobile apps with complicated gestures.

There is, however, a remedy to this issue. A gesture responder mechanism is included in React Native. It will take care of the whole lifespan of all gestures in mobile apps. However, when it comes to more complicated ones, developers will still have some issues. This is due to the fact that both iOS and Android applications employ a unified API that is fairly distinct from one another.

Slower In comparison to Native Apps

React Native is a single-threaded framework that doesn’t allow for simultaneous processing. As a result, when developers want numerous processes to happen at the same time, other components must wait until one is displayed. When developers desire to run numerous processes in parallel, this results in poor performance.

Learning React Native Is Difficult

Learning React Native is challenging, especially for those who are new to the app development field. Developers must be familiar with the fundamentals of coding, as well as the JavaScript programming language. Apart from that, understanding HTML and CSS is required because it is an essential component of web development projects.

Furthermore, developers should be familiar with the platform’s integration of native web technologies, including project settings, continuous integration, and UX requirements. React Native is more harder to grasp than other cross-platform frameworks since it blends HTML elements with JavaScript syntax.

When Should You Opt for React Native App Development?

React Native comes with its own set of benefits and drawbacks. The corporate organisation must make the decision based on what they believe is best for their company. What we can do is assist you in making the best decision possible:

Individual or group views may be created with React Native app development if you’re making native apps. It will aid in the reduction of mobile app development costs. 

React Native applications would be more helpful if the target audience of your website and mobile apps are the same.

Certain mobile applications have data downloading as their primary function and display it to the user. You may utilize React Native in this situation.


Before getting started with React Native, the most popular cross-platform mobile development framework, think about the benefits and drawbacks listed above.

The advantages of RN include speedier development in smaller teams, the ability to reuse code across various platforms, and the availability of several developer-friendly tools.

Be aware that the framework has certain flaws, although they are primarily due to the technology’s infancy and will likely become less onerous in the future. When working on larger or more sophisticated projects, bear in mind that you may need the assistance of native Android and iOS developers.
