Topics Covered :

Uses of React Native:

• React Native is an open-source framework for building Android and iOS applications.

• You can use JavaScript to access your app platform’s APIs as well as to describe the UI using React components.

• Developer Tools

React fundamental concepts:

We’re going to cover the core concepts behind React:

• components

• JSX

• props

• state

NATIVE COMPONENTS:

• Native components are platform-backed components.

• These components are invoked with JavaScript using React components.

• At runtime, React Native creates the corresponding Android and iOS views.

React Native and Expo:

• In React Native, the provided framework requires a basic knowledge of Xcode and Android Studio to build apps

• Expo is a framework of tools and services for React Native that focuses on letting you build apps without Xcode and Android Studio.

JS and UI Threads:

• The JS thread executes the bundled JavaScript code, which then sends actions or requests to the UI thread.

Core vs. Native Components:

• Each core component is implemented using its respective native component counterpart. Because native components are platform-specific, they could look different when rendered on different platforms.

Entry Point:

• import * as React from 'react' ;
  const App = () => (
     // All functionality goes here
  );
  export default App;

• All functionality of the React Native app must be included in a single React component, exported as default from the entry point file.

Packages:

• import { Camera } from 'expo-camera' ;
  import { MapView } from 'react-native-maps' ;

• You can import different packages to gain access to different native APIs or functionality.

Expo SDK:

• The Expo SDK is a collection of packages that allows access to some of the most-used APIs for all apps.

React Native CLI:

• $ react-native init

• React Native provides a CLI tool as the primary interface for developers to start writing code for a project.

Expo Go:

• “Expo Go” is a development client for Android and iOS that can load the JS part of the project. This allows you to preview your app in development.

Expo Snack:

• “Expo Snack” is a web-based playground that allows you to write and run React Native apps in the browser.

Benefits and Drawbacks:

Expo and React Native are ideal tools when you need

(i) to run an app on multiple platforms,

(ii) direct access to native functionality, and/or

(iii) only basic web development and native platform understanding.                                                               

 Expo and React Native aren’t ideal tools when you need

(i) absolute performance, (cutting-edge features that are just released by the platform,

(iii) complex and big applications.                                                                                                                                                

Native Code:

• “Native code” are instructions for how to operate the React Native framework on each platform, such as iOS and Android.
