Pros and Cons of ReactJs Development and its Alternative.


Share post:

Reactjs development is a revolutionary cross-platform framework for app development that is perhaps on similarity to Flutter. Since cross-platform development of apps is growing in popularity and widely used, the use of React Native is increasing constantly. It could be reusable components or having an open source code repository that’s accessible to others or mobile app development, using react native can be a tempting.

The article we’ll examine both the advantages and drawbacks associated with React Native. It will let to decide whether you should choose the framework or choose alternative alternatives. Additionally, it is crucial to select the appropriate framework for developing apps across platforms according to the product you are developing. It will play an important part in the future development of your app.

Pros of React Native

1. One Framework, Multiple Platforms

React Native lets you reuse your codebase (or only a portion or a portion of that) across iOS or Android. In the real world, cross-platform development can be achieved in a certain degree, based on the amount of native components you incorporate into your app.

Certain features will be included as part of npm packages, while others will require to be developed from scratch. The framework will only improve however. React Native community actively promotes the framework and is constantly and is constantly adding more tools in its free source.

Making applications using JavaScript can also provide an opportunity to share codebases not only between mobile platforms , but as well with React web apps. Continuous development of tools like React Native Web seems to be pointing in this direction. This lets the same developers develop both mobile and web applications since the technologies are alike.

2. Fast Applications

There is a lot of debate about whether React Native code might hinder the app’s performance. JavaScript isn’t as fast like native software, however it won’t be noticeable in the majority of cases.

We conducted a test and tested two versions of a basic application developed with React Native and Swift. Both apps produced similar results in terms of performance. There were only minor differences in performance barely noticeable to an average user. If you have more complicated apps, the framework may not be as efficient however you could always move some code to a native module and this won’t be a problem for you anymore.

3. Large developer community

React Native is an open source JavaScript platform which allows developers to contribute their expertise to the development of the framework, that is available to everyone. If a developer encounters problems, they are able to seek out the community for help (as of mid-2020 there were more than 50k active contributors to React Native on Stack Overflow. React Native tag on Stack Overflow). There’s always someone to assist the developer in solving their issue and also have an impact on improving programming skills.

4. It is a thriving ecosystem

Due to the fact that React Native is based on Javascript It has access to a variety of tools and libraries which help developers and speed up the development process.

As of the writing time of this article the repository of libraries for Javascript NPM provides 29,352 results upon typing the term “react-native,” while the equivalent package search engine for Flutter yields only 12,900 results from libraries that are compatible with this framework. That means the list of third-party libraries available for Flutter is only 44% less as React Native.

5. It’s aided by external tools

The development of an application involves more than solely writing code, but also repetitive tasks. Examples include creating (compiling an updated Version of application) as well as testing the application with automated tests, and releasing applications to stores and also investigating and fixing issues.

These repetitive tasks are typically assigned to third party tools or services (3rd third party software) that, once installed, can perform these tasks for developers, who then concentrate on adding new functions. This also prevents the possibility of human error when performing repetitive tasks.


  1. It’s not an native solution.

As I’ve mentioned earlier, React Native is a cross-platform technology that is based on JavaScript. To enable this the creators of the framework needed to design communication protocols between native applications and Javascript (you are able to read the full details here). In this way, applications written using React Native might be slower when compared to native apps and consume more space than native applications.

2. Performance hit

In the majority of instances, React Native performance is at par with native apps.

An RN application is JavaScript mostly.

But there are some things (like UI) that have to be created with Java/Swift/Objective-C. Native modules communicate with the JS part of your application through asynchronous bridges.

Every time you traverse those bridges, the app suffers small performance hits. If your app contains many complex interactions, it could decrease its performance.

3. Need for native developers

There are solutions to certain of the problems above by using native modules.

But implementing them requires Java/Objective-C/Swift expertise. Therefore, you may need assistance by native programmers. This could be a problem for small front-end startups and smaller studios.

Alternatives to React Native

  1. Flutter

The most popular alternative for cross-platform use in comparison to React Native is Flutter, which is a relatively new mobile app framework created by Google.

It is built on it’s predecessor, the Dart programming language and employs an approach that is different to implement cross-platform functions. We at Netguru prefer to stay on top of new technologies, and therefore we conducted some research about Flutter.

  1. Native

The best alternatives that is available to React Native is the separate development of native iOS and Android platforms. This requires two teams working on two distinct apps. This can cause the apps to become inconsistant, and you will not be able to reuse the code.

Wrap Up:

The main benefit of cross-platform software is the simultaneous creation of code that is compatible with both mobile and desktop platforms. It can save time and money.

React Native stands out among other options. Why? because it’s built on the JavaScript programming languagethat is large and active communities. Presently, the number of JavaScript developers available on the market is significantly greater than such languages as Dart (Flutter is a derivative of Dart). A further benefit is the fact that React Native is built upon ReactJS. Because of this, with a team of web-based ReactJS development company, it’s simple to integrate it into the creation of mobile-based applications.
