Steps on How to Build a Video Chat App like Omegle

The most anticipated part of this guide is finally here! So, let’s get started without any more delays. Follow the steps outlined below to create a top-notch video chat application similar to Omegle using ZEGOCLOUD.

1. Integrate the SDK

Integrating ZEGOCLOUD SDK into your project is effortless. Follow these steps to install the SDK for web applications in your project directory using npm:

npm i zego-express-engine-webrtc

Import the SDK into your javascript code using:

var ZegoExpressEngine = require('zego-express-engine-webrtc').ZegoExpressEngine".

2. Create your Omegle chat UI

To create your Omegle-style video chat app, start by designing the user interface. This should feature a call button and a real-time video display window for both the caller and the receiver. Check out the sample code below for a web application and adjust as needed for your chosen tech stack.


    <meta charset="UTF-8">
    <title>Omegle Video Chat</title>
    <style type="text/css">
        * {
            font-family: sans-serif;

        h4 {
            text-align: center;

        #local-video, #remote-video {
            width: 400px;
            height: 300px;
            border: 1px solid #dfdfdf;

        #local-video {
            position: relative;
            margin: 0 auto;
            display: block;

        #remote-video {
            display: flex;
            margin: auto;
            position: relative !important;

        Zego RTC Video Call
    <h4>Local video</h4>
    <div id="local-video"></div>
    <h4>Remote video</h4>
    <div id="remote-video"></div>
    // Copy and paste the JavaScript sample code in the following part of this topic here.
    // const zg = new ZegoExpressEngine(appID, server);


3. Initialize Video Call SDK.

To set up a ZegoExpressEngine object, initialize it with your project’s AppID and access server address as the appID and server parameters.

let appID = ; 
let server = "";

// Instance initialization
const zg = new ZegoExpressEngine(appID, server);

4. Log into a room

To join a room in ZEGOCLOUD, use the loginRoom method with the roomID, token, user, and config parameters. If the room doesn’t exist, it’ll be created, and you’ll be logged in.

Note that authentication is required for room login and needs a Token. You can get a temporary Token from the Admin Console for debugging only, which is valid for 24 hours. For commercial use, generate a Token from your service server. Refer to the documentation for further information on Token-based authentication.

// Set userID, userName, roomID, and token.
let userID = Util.getBrow() + '_' + new Date().getTime();
let userName = "user0001";
let roomID = "0001";
let token = ;

// Listen for the roomStateChanged callback event.
zg.on('roomStateChanged', async (roomID, reason, errorCode, extendedData) => {


// Log in to the room and check if the login is successful.
zg.loginRoom(roomID, token, { userID, userName: userID }, { userUpdate: true }).then(result => {
if (result == true) {
console.log("login success")

5. Create and publish local video streams to ZEGOCLOUD’s audio and video cloud.

To stream audio and video, create a local stream capturing data from the camera and microphone with createStream. Display the stream using a media player or a video element’s srcObject attribute. Publish it to ZEGOCLOUD’s audio and video cloud by providing the streamID and localStream parameters with startPublishingStream.

// The code publishes streams on successful room login. For your own service, streams can be published at any time while the room is connected.

zg.loginRoom(roomID, token, { userID, userName: userID }, { userUpdate: true }).then(async result => {
if (result == true) {
// Create a stream and start the preview.
const localStream = await zg.createStream();
const localView = zg.createLocalStreamView(localStream);"local-video");

       // Start publishing audio and video streams to ZEGOCLOUD.

       let streamID = new Date().getTime().toString();
       zg.startPublishingStream(streamID, localStream)

6. Playing published streams

To play audio and video streams from other users during a video call, you simply need to listen for the roomStreamUpdate callback triggered by the SDK when a user joins the room, providing the streamID of the new user. Then, call the startPlayingStream method, passing in the streamID, to play the remote user’s audio and video stream that was published to the ZEGOCLOUD server.

// Stream status update callback
zg.on('roomStreamUpdate', async (roomID, updateType, streamList, extendedData) => {
// ADD updateType triggers the startPlayingStream method to play the newly added audio and video stream.
if (updateType == 'ADD') {
// Only the first newly added stream is played in this sample code. In a real service, it is recommended to play each stream by traversing the stream list.
const streamID = streamList[0].streamID;
const remoteStream = await zg.startPlayingStream(streamID);

    // Create a media stream player object to play remote media streams.
    const remoteView = zg.createRemoteStreamView(remoteStream);
    // Mount the player to a page. In the sample code, `remote-video` indicates the DOM element ID of the player."remote-video");

} else if (updateType == 'DELETE') {
    // When streams are deleted, stop playing them.

7. Stop a video call

Stop and destroy stream publication.

To stop publishing and eliminate local audio and video streams, use the stopPublishingStream and destroyStream methods respectively. After destroying the stream data, make sure to stop capturing video data by destroying the video.



Stop playing streams

To stop playing audio and video streams from remote users during a video call, use the stopPlayingStream method provided by the SDK.

// Stream status update callback
zg.on('roomStreamUpdate', async (roomID, updateType, streamList, extendedData) => {
    if (updateType == 'ADD') {
        // When streams are added, play them.
    } else if (updateType == 'DELETE') {
        // When streams are deleted, stop playing them based on `streamID` of the streams in the stream deletion list specified by `streamList`.
        const streamID = streamList[0].streamID;

8. Log out of a room

To leave a room, use the logoutRoom function.


Run a Demo

The sample demo source code is readily available for download, allowing you to explore and experiment with the SDK’s features and functionality.


Building an app like Omegle Video Chat requires careful planning, attention to user privacy and security, and a focus on providing an engaging user experience. By following these steps and leveraging technologies like the ZEGOCLOUD Video Call SDK, developers can create a successful and innovative platform that connects people from around the world.
