What Is React Native?

React Native is a JavaScript framework for writing real, natively rendering mobile applications for iOS and Android. It’s based on React, Facebook’s JavaScript library for building user interfaces, but instead of targeting the browser, it targets mobile platforms. 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. 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.
Similar to React for the Web, React Native applications are written using a mixture of JavaScript and XML-esque markup, known as JSX. Then, under the hood, the React Native “bridge” invokes the native rendering APIs in Objective-C (for iOS) or Java (for Android). Thus, your application will render using real mobile UI components, not webviews, and will look and feel like any other mobile application. 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.
React Native currently supports both iOS and Android, and has the potential to expand to future platforms as well. In this book, we’ll cover both iOS and Android. The vast majority of the code we write will be cross-platform. And yes: you can really use React Native to build production-ready mobile applications! Some anecdota: FacebookPalantir, and TaskRabbit are already using it in production for user-facing applications.

Implement Firebase in React-Native

Welcome to React Native Firebase! To get started, you must first setup a Firebase project and install the "app" module. I  Installation Installing React Native Firebase requires a few steps; installing the NPM module, adding the Firebase config files & rebuilding your application. 1. Install via NPM Install the React Native Firebase "app" module to the root of your React Native project with NPM or Yarn: # Using npm npm install --save @react-native-firebase/app # Using Yarn yarn add @react-native-firebase/app The  @react-native-firebase/app  module must be installed before using any other Firebase service. 2. Android Setup To allow the Android app to securely connect to your Firebase project, a configuration file must be downloaded and added to your project. Generating Android credentials On the Firebase console, add a new Android application and enter your projects details. The "Android package name" must match your local projects package name w...

Disadvantages or Drawbacks of React-native

Despite its maturity, React Native still lacks some components. Others, in turn, are underdeveloped. The chances are you won’t have a problem with that, as the majority of custom modules you need are available, well-documented, and working properly. However, it might happen that you will have to build your solution from scratch or try to hack an existing one. When developing your custom modules, you could end up with three codebases (RN, Android, and iOS) for a component instead of only one. In each of those codebases, there can be differences in behaviour and appearance. Fortunately, those situations don’t come about often.
