React Native 9 Pros and 3 Cons

React Native 9 Pros and 3 Cons

Content of the article

RN Technology overview

React Native is a JavaScript framework to build mobile apps that are rendered natively for iOS and Android. Build once the application runs on both iOS and Android devices.

The framework was introduced by Jordan Walke, a Facebook software engineer, as a new tool that simplifies development and improves UX.

The main distinctive point of the technology is that React Native apps functions are similar to the native apps’ ones. They don’t differ from apps built on Objective-C, Swift or Jave and they use the same UI building modules as native iOS or Android apps. But with React Native, building a mobile application takes significantly less time and costs.

React Native Development Pros

Money Saver

React Native development is faster than native approaches. It also requires fewer efforts for the maintenance and team scaling. All that improves the Return Of Investment (ROI) metric.

Multiplatform

Once developed application can be run on iOS and Android and with minimal UX changes on tables.

Release Management

Release management process is faster and simpler with React Native. The same code for both platforms means that if a single feature is ready for Android version it is already done for iOS. Thus all platforms can be released at the same time.

User Experience

It is difficult to differentiate React Native applications from real native applications built on either iOS or Android languages.

The single application can be run on iOS and Android devices and with minimal user interface changes.

  • A feature developed for Android can be released for iOS with minimum efforts.
  • Less time for testing since we have one version for all platforms unlike with Native development when one of a platform can be several versions ahead
  • Since we have one code base development goes faster and testing activities take less time.

Ongoing development and Maintenance

Faster development and less time-consuming maintenance due to we have the same code base and one developer for both platforms.

Performance

React Native applications are transpired to native code so performance is closer to native applications than to hybrid.

Team Scaling

One React Native developer displaces two Native developers in a project, as his code can be applied for both platforms. When you need to scale a team instead of recruiting two engineers you can satisfy the project needs with one.

Stability

You can rely on the framework regarding application stability. Applications build with React Native works very well and having at least not worse than Native applications and are easier in support.

Open Source and Community

React Native is open sourced. Its big community is growing and is supported by Facebook.

If you got an issue it means you can get help from the community.

Also, the community improves code base that positively influences framework stability.

React Native Cons

Native Feature Support

When new feature appears in the platform it takes time to link native modules to create a bridge for React Native.

Bridge creating requires skills in native iOS and Android for a developer.

New Components Quality

React Native framework is a new-made and a very rapidly developing tool, comparing to Native technologies. New features, improvements, upgrades, and changes from time to time could bring unexpected issues.

There are many components with UI and logic bugs so searching for a well-working component that fits project needs could be a challenge for a developer.

Though these don’t affect the production but could create complexities during a development stage.

Games and Computation

Javascript was not built for mathematical operations. And it is not suitable for high CPU and memory usage.

React Native is not the best platform for games and applications with heavy animations. There are libraries which allows doing that but other frameworks which are designed for building games will serve better.

Summary

React Native is a great tool that allows saving resources while creating native-like apps. The capability to use a code for both iOS and Android platforms could be quite beneficial for projects.

For a simple application, React Native could be an efficient approach. But have an eye on its possible drawbacks, especially if your project requires some complex UI, animations and customized features. And consider on Native languages for gaming and math heavy apps  development.
