Reactive native supports web technologies like HTML, CSS, and JavaScript. This is a real advantage enabling developers to use same skill set for writing mobile applications and developing for web. React Native code can be used with little modifications on multiple platforms which can become famous quickly.

React Native applications offer truly native experiences. With React Native, developers can have one set of skills and use it to build applications for multiple platforms. Currently, React Native supports iOS and Android in which maximum app development is done.

Who Is Using React Native?

Given the fact that React Native is a relatively new technology, adoption and usage are quite good. Facebook, Instagram, Airbnb, Walmart, Bloomberg are few big names implementing Reactive Native.

How React Native Works?

Most of the popular solutions for building mobile applications with JavaScript use a Cordova library or a framework built on top of it, such as Ionic. With Cordova, you have access to native API’s, but core of your application will be just HTML and JavaScript rendered in a WebView. While it is possible to reach the look and feel of native UI performance is comparatively better. With React Native your JavaScript-defined components will be rendered as native. A bridge which is an abstraction invokes actual rendering API on the host platform.

A separate thread using JavaScript engine is used to run React Native applications, without blocking the main UI thread. This way, a greater native performance can be achieved along with the smooth animation. Another thread, the third one is used for the layout creation. Styling can be done with CSS syntax. These simple web languages allow creating a clean code.

Benefits of Using React Native

• Cross Platform
• Native Code
• Smaller Learning Curve
• Better, Smoother Developer Experience
• Efficiency

In mobile apps developer’s find some issues regarding performance of Reactive Native. Let’s see what they are and how to overcome them?

Early Development Stage – The Reactive Native has a lot of potential and mobile app technologies are already developed using another language. It will be merely useless to replace reactive in iOS applications especially. Maybe in future, we plan something big that time we can use React Native in mobile apps.

UI implementation is difficult – Declarative UI (animation and gesture) handling becomes difficult to handle in React Native.

Speed Issues – A Native app is much faster and expertly tuned in comparison to React Native app, but especially as improvements continue to be made to the framework, it is often better than a typical iOS app.

Overhead Issue – When JavaScript code is controlling app then there is overhead as JavaScript is unable to handle calculation-intensive tasks, hence handling the native apps become difficult. The nature of native is to use multiple threads while JavaScript has a single dedicated device thread. In performance, React Native stays behind an optimized native application.

Conclusion:

A quick prototyping can be created in React Native at a high rate. Basic features are relatively easy to implement. If needed, they can be extended with native code and native views. The React JS is already used in web development and performing well. Some issues with React Native have discussed above. With optimization of JavaScript, React Native will be the first choice for building apps and to process intensive tasks. As a iOS app development company, we consider React Native as one of prime languages to develop mobile apps in future. To know more on the topic, stay tuned to the other blogs!
