If you’re stuck in a rut, this blog will radically change your perspective and set you to finally determine if your next mobile app is to be of React Native? 

Thinking of building an app for your next project? It’s quite possible that you’re not going to be satisfied with the first technology that you come across. It might as well be possible that you do not click with the seventh technology that you are studying. So you’ve got to get good with rejection.

That’s absolutely fine. When you try tons and reject each one of them, that is the origination of the latest idea upon which you wish to build up your app and so has anyone who has ever tried anything worthwhile.

It sounds crazy, but rejection is what’s going to guarantee your results. Losing the fear means you’re not losing out on opportunities anymore. When you actually pause your search, get off your couch and get off in the real world for developing your next React Native app.

What is React Native Technology?

React Native is actually a JavaScript framework that closely resembles Native (Facebook’s library) used for building interfaces for mobile platforms instead of targeting web browsers. Efficiently used at one fell swoop to create Android as well as iOS applications, it expeditiously coalesces native app development with JavaScript UI development.  

React Native applications make use of JavaScript Syntax extension (JSX) which combines XML with JavaScript. Most prevalent examples are Airbnb, Skype, Instagram, Facebook, Bloomberg, UberEATS Vogue, Baidu Mobile, Walmart, and Tesla.

What is React Native Development?

Web developers can now develop applications that give a truly native experience, still making use of JavaScript library being widely excepted by developers. While it allows a lot of code being shared in between platforms, it is suitable for both Android and iOS simultaneously. 

React Native applications are developed by making use of JSX, they are similar to React that are used to create web applications. 

React Native invokes the native rendering APIs created in Objective C (for iOS) or Java (for Android). The application will thus render real mobile UI components (instead of 

webviews) and the mobile applications resemble as usual. React native apps are able to access major platform features like camera, phone, GPS etc., therefore it exposes JavaScript interfaces for platform API’s.

A customer always looks for a smooth development experience (an app that follows all states of app development life cycle and his high on performance) irrespective of the platform. Cluster bombs cannot be targeted precisely, thus here are some of the reasons that have led to the immense popularity of React Native:

  • React Native is independent of a platform of development (React Native was initially developed to support iOS components but it now supports Android operating system) 
  • It is readily available for reusable components (It contains responsive UI and UX, web-like style of development as compared to hybrid frameworks and give a feeling of native widgets)
  • React native is useful in revamping code (Useful in supplementing the app that exists but does not need to be rebuilt. This often involves embedding React Native UI components for quick responses that do not require re-writing of code) 
  • React Native supports hot-reloading. With all the best features of JavaScript, React Native is high on speed and agility of web apps to the hybrid apps with results similar to that of native apps

The facts that makes React Native stand out amongst a host of existing features are that it makes use of hot platform’s standard rendering API’s, like Cordova and Ionic. React Native also translates the markups to real, native UI elements thus enhancing the means of rendering views on the platform you’re working on. React Native leverages the UI libraries of its host platform, rather than using HTML and CSS markup.

Other existing methods of writing mobile applications are a combination of JavaScript, CSS, and HTML and are usually rendered by making use of webviews. This performance can be low on performance and these also do not have access to the host platform’s set of native UI elements. React Native developers usually experience an improvement in two areas: the developer experience and cross-platform development. 

What should I build React Native apps?

It is often difficult to customize the applications developed with react native at a later stage as it is not completely scaled for custom modules. It takes a lot of time to build and only developers experienced to build react native apps are able to address the technical challenges faced by such applications periodically.

React Native might not be able to provide best native experience in case the application is more interactive. It is able to handle only simple apps that do not require much of background process work. Heavier and intensive apps might be difficult to handle via react native.

React Native works on JavaScript and Native modules and combines the power of script compilation to give a native feel to the app. All this process is highly CPU intensive which is the major cause of low app performance. Examples of selective Famous Applications with React Native:

Totting Up

Does your app really need to be built with React Native? While it may be interesting to make native apps in certain situations like:

  • The application needs to be built with faster calculations and processing
  • There are more than one threads in a process
  • Apps are strongly coded with fewer bugs
  • Apps have easy and parallel updates with SDK’s
  • The application is stuffed with heavy UI and a lot of animations

But what make React Native win in front of native app development are its traditional native-like apps that are suitable for cross-platforms with fewer views. The applications have less hardware API access. Developers can make React Native apps within budget. These have a short development cycle. Finding all the benefits of an app can be the trickiest part but what is more appalling is to sanction an app development platform. While developers can’t resist features to make native apps, React Native steals the show even after being heavy CPU consumer.
