Create a sample app

This section contains instructions to create a simple React Native Video Conferencing app. We will help you with instructions to understand the project setup and complete code sample to implement this quickly.

Prerequisites

Create a React Native app

Once you have the prerequisites, follow the steps below to create a React Native app. This guide will use VS code but you can use any code editor or IDE.

  1. Open your Terminal and navigate to directory/folder where you would like to create your app.

  2. Run the below command to create React Native app:

npx react-native init PrebuiltSampleApp --version 0.68.5 --npm && cd ./PrebuiltSampleApp
  1. Once the app is created, open it in VS code.

  2. Test run your app

    a. Build the App ​

    npx react-native run-android

    b. Start Metro Bundler if it is not already started ​

    npx react-native start

    or follow instructions printed in Terminal to start the Metro Bundler or Run the Application.

Install the Dependencies

npm

After the Test run of your app is successful, you can install 100ms React Native Room Kit package in your app.

npm install --save @100mslive/react-native-room-kit

Install the Peer Dependencies

  1. react-native-permissions package Since the app and @100mslive/react-native-room-kit package requires Camera & Microphone permissions, a package for requesting these permissions from users should also be installed. We recommend using the react-native-permissions package.
npm install react-native-permissions@3.4.0

Native File Changes for react-native-permissions package -

  1. Allow camera, recording audio and internet permissions by adding the below snippet to the AndroidManifest.xml file (at the application tag level).
<uses-feature android:name="android.hardware.camera"/> <uses-feature android:name="android.hardware.camera.autofocus"/> <uses-permission android:name="android.permission.CAMERA"/> <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE"/> <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"/> <uses-permission android:name="android.permission.RECORD_AUDIO"/> <uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> <uses-permission android:name="android.permission.FOREGROUND_SERVICE" /> <uses-permission android:name="android.permission.BLUETOOTH" android:maxSdkVersion="30" /> <uses-permission android:name="android.permission.BLUETOOTH_CONNECT" /> <uses-permission android:name="android.permission.VIBRATE" /> <uses-permission android:name="android.permission.POST_NOTIFICATIONS" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
  1. Change minSdkVersion to 24 in the android/build.gradle file
buildscript { ext { ...
minSdkVersion = 24
... } }

If you see any permission related error, then check out react-native-permissions library setup guide for v3.4.0.

Note: If you have already setup the react-native-permissions package, then you can continue with your existing setup.

Note: iOS simulator and android emulator doesn't support actual video, you need actual devices to see your video in real-time.

  1. react-native-reanimated package react-native-reanimated package is required for adding animated views.

Note: If you already have the setup for react-native-reanimated package, then skip this step. We support minimum >= 2.x.x versions.

npm install react-native-reanimated@2.17.0

Add Reanimated's babel plugin to your babel.config.js

module.exports = { presets: [ ... ], plugins: [ ...
'react-native-reanimated/plugin',
], };

For iOS, do run pod install in the ios/ directory.

Install the dependencies of react-native-room-kit package

react-native-room-kit package depends upon many other packages. These packages to be your app's direct dependencies so that react-native can link them.

npm install @100mslive/react-native-hms @100mslive/types-prebuilt @react-native-community/blur@^4.3.2 @react-native-masked-view/masked-view@^0.2.9 @shopify/flash-list@1.4.3 lottie-react-native@5.1.6 react-native-gesture-handler@2.12.1 react-native-linear-gradient@2.7.3 react-native-modal react-native-safe-area-context@3.3.0 react-native-simple-toast@1.1.3

Ensure that the final package.json file contains the following dependencies -

"@100mslive/react-native-room-kit": "^1.0.3", "@100mslive/react-native-hms": "^1.9.2", "@100mslive/types-prebuilt": "^0.12.7", "@react-native-community/blur": "^4.3.2", "@react-native-masked-view/masked-view": "^0.2.9", "@shopify/flash-list": "1.4.3", "lottie-react-native": "5.1.6", "react-native-gesture-handler": "2.12.1", "react-native-linear-gradient": "2.7.3", "react-native-modal": "^13.0.1", "react-native-permissions": "3.4.0", "react-native-reanimated": "2.17.0", "react-native-safe-area-context": "3.3.0", "react-native-simple-toast": "1.1.3"
  1. Native File Changes for @100mslive/react-native-hms package

Change ios target platform version to '13.0' in the ios/Podfile file

require_relative '../node_modules/react-native/scripts/react_native_pods' require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'
platform :ios, '13.0'
install! 'cocoapods', :deterministic_uuids => false

Follow the official installation steps of these libraries if you encounter any problems in setup.

Note: If you already have the setup for any of the listed package, then you may continue with your existing setup. If some problem occurs then try using specified version for the package.

Configure Inter Font Family

react-native-room-kit package uses 'Inter' font family for texts. You need to add 'Inter' fonts in your app.

Enable Background modes for iOS

You can enable background modes for audio in iOS. so that when you minimze the app, room audio can still be heared by the users.

Paste the following in your Info.plist file -

<dict> ...
<key>UIBackgroundModes</key>
<array>
<string>audio</string>
</array>
... </dict>

Additional Setup

You can follow ScreenShare setup and AudioShare setup guides to add ScreenShare and Audio Share features in your app.

After doing changes related to ScreenShare feature, To use screenshare feature on iOS, pass appGroup and preferredExtension options to HMSPrebuilt componnets -

<HMSPrebuilt roomCode="..." options={{ ... ios: {
appGroup: "...";
preferredExtension: "...";
} }} />

Prebuilt Properties

<HMSPrebuilt roomCode={roomCode} options={{ userName: "John Appleseed", userId: "My_Unique_UserId", ios: { appGroup: 'group.rnroomkit', preferredExtension: 'live.100ms.reactnative.RNExampleBroadcastUpload', }, }} onLeave={handleRoomLeave} handleBackButton={isScreenFocused} autoEnterPipMode={true} /> const handleRoomLeave: OnLeaveHandler = useCallback((reason) => { console.log(':: Reason for Leaving the Room > ', reason); navigation.navigate('HomeScreen'); }, []);

Complete code example

Now that your project setup is complete, let's replace the code in the App.js file with the complete code sample below -

import React, { useState } from 'react'; import { StatusBar, StyleSheet, Button, View } from 'react-native'; import { HMSPrebuilt } from '@100mslive/react-native-room-kit'; const App = () => { const [showHMSPrebuilt, setShowHMSPrebuilt] = useState(false); return ( <View style={styles.container}> <StatusBar barStyle={'dark-content'} /> {showHMSPrebuilt ? ( <HMSPrebuilt roomCode='abc-lmno-xyz' options={{ userName: 'John Appleseed' }} /> ) : ( <View style={styles.joinContainer}> <Button title='Start' onPress={() => setShowHMSPrebuilt(true)} /> </View> )} </View> ); }; const styles = StyleSheet.create({ container: { flex: 1, }, joinContainer: { flex: 1, alignItems: 'center', justifyContent: 'center' } }); export default App;

Test the app

Follow the instructions in one of the tabs below based on the target platform you wish to test the app.

a. Build the App

npx react-native run-android

b. Start Metro Bundler if it is not already started

npx react-native start

or follow instructions printed in Terminal to start the Metro Bundler or Run the Application.
