Steps for ZEGOCLOUD Live Streaming SDK Integration

To build our live video streaming web app, we have to integrate the ZEGOCLOUD SDK for live video streaming into our project. We can do so through the following steps :

Create a new project.

Creating a project is the starting point of our application. You can skip this step if you already have the project. Follow the steps below to create a project :

  1. Create a folder with the name of your project.
  2. Create these three files: index.html,index.jsinside the js directory, and index.css inside the css directory, all inside the folder created in step (1).

Here’s a breakdown of what the files we created do:

  • index.html file: The front page file of the audio and video call application.
  • index.js file under the js directory: The JavaScript code that is used to implement the audio and video features
  • index.css file under the css directory: used to set the page style.

After creating these files, open them with your favorite IDE or text editor. I will be using Visual Studio Code. Your folder structure should look like the one in the image below after adding the files we created in step (2).

├── index.html
├── js
│   └── index.js
└── css
   └── index.css

Follow the steps below to create root files and test the setup:

1. Copy the following code to the index.html file:
<!DOCTYPE html>
    <meta charset="UTF-8">
    <title>Zego RTC Video Call</title>
    <link rel="stylesheet" href="./css/index.css">
        Zego RTC Video Call
    <h4>Local video</h4>
    <video id="local-video" autoplay muted playsinline controls></video>
    <h4>Remote video</h4>
    <video id="remote-video" autoplay muted playsinline controls></video>
    <script src="./js/index.js"></script>
2. Copy the following code to the index.css file:
    font-family: sans-serif;
    text-align: center;
video {
    width: 300px;
    height: auto;
    position: relative;
    margin: 0 auto;
    display: block;

    display: flex;
    height: auto;
    margin: auto;
    position: relative !important;
3. Run and test out your project on the local Web server.

You can do this by simply opening the index.html file we created with any web browser of your choice as long as it passes the Zego Live compatibility test or by using the live-server extension.

Run the code below to install Live-Server:

npm i live-server -g

Enter your root directory and run a live-server command to test the project.

Import the SDK

Follow the steps below to import the ZEGOCLOUD SDK into our project:

  1. Run the command below to install ZEGOCLOUD SDK.
npm i zego-express-engine-webrtc
  1. Import the ZEGOCLOUD SDK by copying the code below to the index.js file.
import {ZegoExpressEngine} from 'zego-express-engine-webrtc'

Implementation steps

We have so far imported our ZEGOCLOUD SDK, which we are going to use to set up our live video streaming.

The diagram below shows the working principle of the ZEGOCLOUD SDK when User A plays a stream published by User B:

live video stream sequence

Create a ZegoExpressEngine instance.

Create a single instance of the ZegoExpressEngine class and pass in your app ID as the appIDparameter and the server URL as the server parameter. You can obtain them from the ZegoCloud Admin Console.

// Initialize the ZegoExpressEngine instance
const zg = new ZegoExpressEngine(appID, server);

Log in to a room

To log in to a room, call the loginRoom with the following parameters:

  • Enter a unique room ID in the roomID parameter.
  • Enter the login token in the token parameter. See User Privilege Control for more details.
  • The user ID and user name are the roomID userName parameters.
  • Optional: Pass the corresponding object to the config parameter based on the actual situation.
// Log in to a room. It returns `true` if the login is successful.
// The roomUserUpdate callback is disabled by default. To receive this callback, you must set the `userUpdate` property to `true` when logging in to a room. 
const result = await zg.loginRoom(roomID, token, {userID, userName}, {userUpdate: true});

Note: If the roomID you entered does not exist, a new room will be created, and you will log in automatically when you call the loginRoom method.

We’ll create some callback events that return information on the status of a room. Below are some common event callbacks related to room users and streams:

  • roomStateUpdate: Callback for updates on the current user’s room connection status. ZEGOCLOUD SDK sends a notification event when the current status of the user’s room changes. for instance, when a login authentication fails or a user is disconnected.
  • roomUserUpdate: This callback is for information or an update on the current status of other users in the room. When other users join or leave the room, the SDK sends out the event notification through this callback.
  • roomStreamUpdate: Callback for updates on the status of the streams in the room. When new streams are published to the room or existing streams in the room stop, the SDK sends out the event notification through this callback.
// Callback for updates on the current user's room connection status.
zg.on('roomStateUpdate', (roomID,state,errorCode,extendedData) => {
    if (state == 'DISCONNECTED') {
        // Disconnected from the room

    if (state == 'CONNECTING') {
        // Connecting to the room

    if (state == 'CONNECTED') {
        // Connected to the room

// Callback for updates on the status of other users in the room.
zg.on('roomUserUpdate', (roomID, updateType, userList) => {
        `roomUserUpdate: room ${roomID}, user ${updateType === 'ADD' ? 'added' : 'left'} `,

// Callback for updates on the status of the streams in the room.
zg.on('roomStreamUpdate', async (roomID, updateType, streamList, extendedData) => {
    if (updateType == 'ADD') {
        // New stream added, start playing the stream. 
    } else if (updateType == 'DELETE') {
        // Stream deleted, stop playing the stream.

Publish streams

You can create a local audio and video stream on Zego Live by calling the createStream method. This activates our camera and microphone for real-time video and audio data capture.

// After calling the CreateStream method, you need to wait for the ZEGO server to return the local stream object before any further operation.
const localStream = await zg.createStream();
// Obtain the video tag of the local video.
const localVideo = document.getElementById('local-video');
// The local stream is a MediaStream object. You can render audio and video by assigning the local stream to the SrCObject property of video or audio.
localVideo.srcObject = localStream;

Note: After calling the createStreammethod, you need to wait for the ZEGO server to return the media stream object (localStream) before any further operations.

If you wish to start publishing a local audio and video stream to remote users, call the startPublishingStream method with the following parameters:

// localStream is the MediaStream object created by calling creatStream in the previous step.
zg.startPublishingStream(streamID, localStream)
  • a stream ID as the streamID parameter
  • The media stream object obtained in the previous step is passed as the localStream parameter.

You can get information about your published streams with the following callbacks:

zg.on('publisherStateUpdate', result => {
    // Callback for updates on stream publishing status.
    // ... 

zg.on('publishQualityUpdate', (streamID, stats) => {
    // Callback for reporting stream publishing quality.
    // ... 
  1. publisherStateUpdate: Callback for updates on stream publishing status. After stream publishing starts, if the status changes, the SDK sends out the event notification through this callback.
  2. publishQualityUpdate: Callback for reporting stream publishing quality. After stream publishing starts, the SDK sends out the streaming quality data (resolution, frame rate, bit rate, etc.) regularly through this callback.

Play streams

To start playing a remote audio and video stream from the ZEGO server, call the startPlayingStream method with the corresponding stream ID passed to the streamIDparameter.

You can obtain the stream ID of the streams published by remote users from the callback roomStreamUpdate.

const remoteStream = await zg.startPlayingStream(streamID);

// The remoteVideo object is the <video> or <audio> element on your webpage.
remoteVideo.srcObject = remoteStream;

Stop publishing and playing streams.

We are done streaming; how then do we terminate it? You can easily do so with the command below.

Stop publishing stream command:


Destroy stream command:

// localStream is the MediaStream object created when calling the createStream method.

stop playing stream command:


Log out of a room

You can see that the ZEGOCLOUD SDK is very straightforward. To log out of a room, just call the logoutRoom method with the corresponding room ID passed to the roomID parameter.

js zg.logoutRoom(roomID)


Incorporating a live streaming SDK in your live streaming app is essential for ensuring a smooth and uninterrupted video streaming experience for your users.
