Steps on How to Build Your Own Twitch App Clone

If you’re looking to create your own live streaming platform like Twitch, it’s important to understand the key steps involved in building a successful Twitch app clone. Here’s a brief step to get you started:

Preparation

ZEGOCLOUD developer account – Sign up
A computer with internet and web access
Basic knowledge of web development
Have NodeJS installed

1. Create a new project

Once you’ve set up your development environment, simply execute the command below to initiate the creation of your project:

react-native init YourProject

2. Import the SDK

Add "zego-express-engine-reactnative": "^x.y.z" to the dependencies in package.json, located in the project’s root directory.
Install the SDK by running either “npm install zego-express-engine-reactnative --save” or “yarn add zego-express-engine-reactnative” in your project’s root directory.
Install dependencies by running “pod install” in the iOS root directory.

3. Add permissions

Android

Insert the code below into app/src/main/AndroidManifest.xml:

<!-- Permissions required by the SDK -->
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<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.CAMERA" />
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<!-- Permissions required by the App -->
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />

<uses-feature
    android:glEsVersion="0x00020000"
    android:required="true" />

<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />

For certain crucial permissions, Android 6.0 mandates dynamic permissions. Once you have acquired static permissions using AndroidManifest.xml, refer to the code below to request dynamic permissions.

import {PermissionsAndroid} from 'react-native';

const granted = PermissionsAndroid.check(PermissionsAndroid.PERMISSIONS.CAMERA,
                                        PermissionsAndroid.RECORD_AUDIO);
granted.then((data)=>{

        if(!data) {
            const permissions = [PermissionsAndroid.PERMISSIONS.RECORD_AUDIO, PermissionsAndroid.PERMISSIONS.CAMERA];
            PermissionsAndroid.requestMultiple(permissions);
        }
    }).catch((err)=>{
    console.log(err.toString());
    })
}

iOS

Choose the target project in Xcode, then navigate to Info > Custom iOS Target Properties.

Add the following permissions: Privacy - Camera Usage Description and Privacy - Microphone Usage Description. The permissions will be shown with a + button after being added.

4. Create a ZegoExpressEngine instance

To obtain an individual class of the ZegoExpressEngine, make use of the createEngine function along with your AppID that corresponds to your project. Call the on method after creating a ZegoExpressEngine instance to receive callbacks. Handle and listen to the callbacks as required. Check out ZegoEventListener for more information about event callbacks.

// Import the ZegoExpressEngine
import ZegoExpressEngine from 'zego-express-engine-reactnative';

const profile = {
appID : xxx,
scenario : 0
};

ZegoExpressEngine.createEngineWithProfile(profile)

5. Log in to a room

To join a room, use the loginRoom method.

// set the token
let roomConfig = {};
roomConfig.token = "xxxx";
// log in to a room
ZegoExpressEngine.instance().loginRoom('room1', {'userID': 'id1', 'userName': 'user1'}, roomConfig);

Implement the appropriate event callback methods of the event handler to handle various events that may occur after joining a room. Below are some common event callbacks that relate to room users and streams:

roomStateUpdate: notifies changes in the current user’s room connection status, such as disconnection or failed login authentication.
roomUserUpdate: notifies changes in the status of other users in the room, such as joining or leaving the room.
roomStreamUpdate: notifies changes in the status of the streams in the room, such as publishing new streams or stopping existing ones.

ZegoExpressEngine.instance().on('roomStateUpdate', (roomID, state, errorCode, extendedData) => {


  // Callback for current user's room connection status updates.

 // SDK sends connection status updates through the 'roomStateUpdate' callback.


}); ;


ZegoExpressEngine.instance().on('roomUserUpdate', (roomID, updateType, userList) => {

  // When other users join or leave the room, this callback is triggered by the SDK.

});

ZegoExpressEngine.instance().on('roomStreamUpdate', (roomID, updateType, streamList) => 

  // Callback for updates on the status of the streams in the room, including new stream publications and existing stream stops.

});

6. Publish streams

Start publishing a stream

Begin transmitting a local audio or video stream to remote users by utilizing the startPublishingStream method and passing the corresponding Stream ID to the streamID parameter.

ZegoExpressEngine.instance().startPublishingStream("streamID");

Implement the necessary event callback methods of the event handler to handle various events that may occur after stream publishing starts, just like the one below:

publisherStateUpdate: notifies changes in the stream publishing status, such as interruption due to network problems or the SDK restarting stream publishing.

ZegoExpressEngine.instance().on("PublisherStateUpdate", (streamID, state, errorCode, extendedData) => {
    // Callback for updates on stream publishing status.

});

7. Play streams

Start playing a stream

Begin playback of a remote audio or video stream by using the startPlayingStream method, providing the corresponding Stream ID to the streamID parameter, and the designated view for rendering the video to the view parameter.

To retrieve the stream IDs of streams published by other users in the room, make use of the roomStreamUpdate callback function.

import { findNodeHandle } from 'react-native';

// Use the Ref attribute from React to enable local video preview on a view.

let remoteViewRef = findNodeHandle(this.refs.zego_play_view);

// Start playing a stream
ZegoExpressEngine.instance().startPlayingStream("streamID", {
    'reactTag': remoteViewRef,
    'viewMode': 0,
    'backgroundColor': 0
});

// React render
render() {
    return (
        <View>
            <ZegoTextureView ref='zego_play_view'/>
        </view>
    )
}

8. Stop publishing and playing streams

Stop publishing a stream

End the publishing of a local audio or video stream to remote users by invoking the stopPublishingStream method.

ZegoExpressEngine.instance().stopPublishingStream();

Stop the local video preview

End the local video preview by calling the stopPreview method whenever necessary.

ZegoExpressEngine.instance().stopPreview();

Stop playing a stream

Call the stopPlayingStream method with the stream ID of the stream to be stopped passed to the streamID parameter to stop playing a remote audio or video stream.

ZegoExpressEngine.instance().stopPlayingStream("streamID");

9. Log out of a room

Call the logoutRoom method with the corresponding room ID passed to the roomID parameter to log out of a room. When you log out successfully, the SDK sends out a notification of the change of room connection status through the callback roomStateUpdate. This will stop all stream publishing, stream playing, and local video preview.

ZegoExpressEngine.instance().logoutRoom('room1');

10. Destroy the ZegoExpressEngine instance

Call the destroyEngine method to release resources and destroy the ZegoExpressEngine instance.

ZegoExpressEngine.destroyEngine();

Run a Demo

Test real-time audio and video by joining the same room in the ZEGO Express Web Demo using the same AppID, Server, and RoomID. If successful, both local and remote videos and audio will be visible.
