React Native

What is React Native?

React Native is an open-source mobile application framework created by Facebook. It is used to develop applications for Android, iOS, Web and UWP by enabling developers to use React along with native platform capabilities. React Native combines the best parts of native development with React, a best-in-class JavaScript library for building user interfaces.

Understanding React Native

React Native allows you to build mobile apps using only JavaScript. It uses the same design as React, letting you compose a rich mobile UI from declarative components. With React Native, you don’t build a “mobile web app”, an “HTML5 app”, or a “hybrid app”. You build a real mobile app that’s indistinguishable from an app built using Objective-C or Java. React Native uses the same fundamental UI building blocks as regular iOS and Android apps. You just put those building blocks together using JavaScript and React.

Key Features of React Native

  • Fast Refresh: See your changes as soon as you save. With the power of JavaScript, React Native lets you iterate at lightning speed. No more waiting for native builds to finish. Save, see, repeat.
  • Native Components: Use native components controlled by JavaScript. React Native works with all the native platforms like iOS and Android, and it uses the components from these platforms to render the UI. This makes the apps developed in React Native perform as good as the native apps.
  • Learn Once, Write Anywhere: React Native is unique because its dynamic code updates, it can push updates to devices without requiring an application release. With React Native, one team can maintain two platforms and share a common technology—React.

Why use React Native?

React Native is a popular choice for developers because of its efficiency and speed. It allows for simultaneous development on iOS and Android, which significantly reduces development time. Its component-based structure allows developers to build apps with a more agile, web-style approach than typical hybrid frameworks, and without any web at all. This, coupled with the fact that a vast majority of the code can be shared between platforms, makes React Native a compelling choice for those looking to build apps on both iOS and Android.

Getting Started with React Native

To get started with React Native, you will need to install Node.js and the React Native command line interface. You will also need Xcode for iOS development and Android Studio for Android development. Once you have these installed, you can create a new React Native project using the command line interface.

Overall, React Native provides a robust framework for building mobile apps using the familiar tools of JavaScript and React. Its ability to deliver high-performance apps with a single codebase makes it a popular choice among developers.
