If you haven’t heard the term yet, AndroidX is the new open-source project being rolled out by Google to package librairies with Jetpack. And yes: you can really use React Native to build production-ready mobile applications! Some example: Facebook, Palantir, and TaskRabbit are already using it in production for user-facing applications. The vast majority of the code we write will be cross-platform. In this blog, we’ll cover both iOS and Android. React Native currently supports both iOS and Android and has the potential to expand to future platforms as well. React Native also exposes JavaScript interfaces for platform APIs, so your React Native apps can access platform features like the phone camera, or the user’s location. Thus, your application will render using real mobile UI components, not webviews, and will look and feel like any other mobile application. Then, under the hood, the React Native “bridge” invokes the native rendering APIs in Objective-C (for iOS) or Java (for Android).

Similar to React for the Web, React Native applications are written using a mixture of JavaScript and XML markup, known as JSX. Plus, because most of the code you write can be shared between platforms, React Native makes it easy to simultaneously develop for both Android and iOS. In other words: web developers can now write mobile applications that look and feel truly “native,” all from the comfort of a JavaScript library that we already know and love. It’s based on React, Facebook’s JavaScript library for building user interfaces, but instead of targeting the browser, it targets mobile platforms. React Native is a JavaScript framework for writing real, natively rendering mobile applications for iOS and Android. It uses the same design as React, letting you compose a rich mobile UI using declarative components. React Native lets you build mobile apps using only JavaScript.
