Cross-platform development: What is it?

Cross-platform development is simply the practice of software designing which is compatible with multiple platform types. Any cross-platform app can run smoothly on Linux, macOS and Microsoft Windows, and an ideal example would be Adobe Flash. Irrespective of the platform or device, Adobe Flash will perform exactly the same. The most popular cross-platform frameworks are:

  • Xamarin
  • Flutter
  • React Native
  • Ionic

What is React Native?

React Native, acronym as RN, is a JavaScript-based, open-source, cross-platform framework compatible with iOS, Android and Windows OS. It allows software developers to design applications for multiple platforms by using an identical codebase. 

Facebook released it in 2015, and today, it is used by almost every other leading mobile application globally.

Features of React Native

These key features of React Native make it a hit:


React Native is a time-saving framework that can quickly detect which platform is being used to build the application, generating the codes accordingly. In addition, it is developer-friendly and time-savvy because once a code is written, it can be reused multiple times.

It offers a built-in debugging feature

React Native offers a unique built-in debugging feature due to the addition of a debugging tool to it in 2020 named Flipper. Thus, it allows developers to view the network requests and crash reports, gives them access to edit the databases of devices, etc.

It doesn’t demand in-depth technical knowledge

React Native doesn’t require high-level technical expertise or understanding, making it very popular among front-end developers. Any person with JavaScript background or exposure to ReactJS is perfectly eligible to design applications with React Native.

Strong community support

React Native is a favourite among software developers globally. Naturally, it is backed by strong community support, simplifying the learning process by offering excellent support.

Third-party library access

React Native offers easy third party library access, thus, providing extended support to the learners.

React Native Components

The core components to know about in a React Native tutorial are:


It is a built-in component where the content is displayed. You can also use View for arranging the content. In addition, this fundamental component supports layout with controls of accessibility, style, flexbox, etc. For example, users can use the ‘View’ option when they need a unique style for a particular element or require any nested element.

State and Props

Any component is controlled by two data types – state and props (or properties). The State is mutable, while Props aren’t, meaning State can modify or change any value, but Props cannot. The State determines the component behaviour, how it may render in the future, etc. Props are used for passing data across various components.


The style component makes applications attractive. There are two options for styling purposes in React Native: inline style and StyleSheet.

Flex layout

This component gives a cleaner layout to the content. The layout can be modified by options like flexDirection, alignItems, justifyContent, etc.


Navigators are vital components used for changing scenes in applications consisting of multiple scenes.
