A Quick Dive into React Native

Once accost as a revolution in mobile development, Facebook’s React Native framework is helping in gaining users. Developers are reassessing their commitment to the platform and technology and Facebook is looking to overcome it.

Since inception, React Native has been used at companies like Instagram, Uber to Tesla, and even Facebook itself. Those who are experts in the world of application development must have heard about React Native and experienced the benefits that come with it. But, for those who are new to this domain of application development – React Native is something you do not want to miss out on!

What is React Native?

React Native is a framework which helps developers to build robust world-class applications on Native platforms using the two pillars of JavaScript AND React. React Native is a step ahead of React which is basically a code library for JavaScript. React was developed by Facebook and Instagram. React Native is now open source for both Android and iPhone.

Building Native apps mean the app code is written for a specific operating system. The major advantage of using React Native is you can reuse the code to write the code for an app, which is being developed for another application. And once you learn this you could keep writing anywhere.

Presently, Android and iOS have different code bases, hence developing apps for both require different codes and hence a completely different development team is needed. This puts a lot of financial pressure on small businesses that are basically entering the market with mobile applications. So, no more writing code from scratch, simply reuse the code for different OS.

Features of React Native

  • Native components such as UITabBar on iOS and Drawer on Android help to give a consistent look and feel to the application with respect to the rest of the platform ecosystem.
  • React Native brings a new level of fluidity and responsiveness to all applications as the code execution is asynchronous.
  • Ever wondered how seamlessly you scroll across an app? Well, React Native’s touch handling feature takes care of that. It ensures that the touch easily negotiates through views with complex hierarchies without requiring any extra configuration.
  • Creating a view layout on an app should be easy, and with React Native it definitely is! The Flexbox styling model helps you build superior UI layouts easily. Stacked layouts, nested boxes, padded boxes- everything can be made with this. Apart from that it also support some of the most common and widely used web styles.
  • Reusability of code with React Native has already been seen. But extensibility of Native codes and views is also possible.
  • You can also integrate it with an existing app which can be a non-React Native app.
  • You can choose from a host of UI components which are available in the React Native library or are already there on the platform. Some examples of UI widgets are: ScrollView and TextInput.
  • While developing an app, you also need to ensure that the app is accessible by users with disabilities. React Native comes with various APIs which make apps accessible to one and all.

So, now that you have a brief understanding of what React Native is and how it works – go ahead and build your next app on this fantastic platform!
