How to Build WebRTC Live Streaming App

How to Build WebRTC Live Streaming App

We make use of live streaming technologies on a daily basis, even without realizing it. For instance, placing a video call, be it a Zoom meeting, conference call, or normal one-on-one call, requires the real-time data transfer that the live streaming kit provides. We’ll learn how to use Live Streaming Kit from ZEGOCLOUD to build a full-fledged live streaming application with ease.

Can I Use WebRTC for Live Video Streaming?

WebRTC is a free and open-source technology that allows real-time communication between web browsers and mobile applications. It has built-in support for audio and video streaming, along with data channels for peer-to-peer communication. It can be used for various use cases such as video conferencing, online education, remote work, and of course, live video streaming. You can achieve low-latency, high-quality video streaming without the need for plugins or third-party software with WebRTC.

Step by Steps for Live Streaming Kit SDK Integration

Follow the steps below to get ZEGOCLOUD’s Live Streaming Kit up and running :

Step 1: Login to the ZEGOCLOUD admin console

To make the whole process easier, ZEGOCLOUD has a powerful admin console where you can manage your projects. You can create projects through the ZEGOCLOUD admin console. And of course, the Live Streaming Kit is among the types of projects you can create. Pretty cool, right? Hit the login button to get started with the best live streaming kit.

log in

Step 2: Add a new project

You’ll see the add button after logging in to your admin console. Click on it to get started with Live Streaming Kit integration.


After clicking the add button. You’ll be prompted to select the type of app we want to build. Select Live Streaming.


Step 3: Type in the project name.

From the steps so far, you can see that creating real-time applications with ZEGOCLOUD is very straightforward and simple.

Back to our Live Streaming Kit integration. At this point, we’re required to pick a name for our project.

Note: a project name will only contain numbers, letters, and underlines (_).

You can choose whatever name you like. Provided that you follow the rules.

Step 4: UI customization kits.

If you scroll down after entering the project name, you’ll see a window where you can select UI customization options. Two options exist. There are “Prebuilt UIkit” and “Custom UIkit”. The custom UIkit gives you advanced customization options and low-level SDK customization. I will be going with Prebuilt UIKit since we’re just testing our Live Streaming Kit

You can proceed with the building process. Wait for the project to be completed.


Step 5: Choose a platform and download configuration files.

At this point, All that you’re required to do is to select the platform for our Live Streaming SDK. I will be using Web this as my platform for this project. Congratulations! We’ve successfully created our first web live streaming application with ZEGOCLOUD’s Live Streaming Kit.


Click on Get configuration and integration files to download project files.


Opening the downloaded configuration and integration file reveals the following lines of code:


        #root {
            width: 100vw;
            height: 100vh;

    <div id="root"></div>
<script src=""></script>
<script src=""></script>
<script src=""></script>
window.onload = function () {
    function getUrlParams(url) {
        let urlStr = url.split('?')[1];
        const urlSearchParams = new URLSearchParams(urlStr);
        const result = Object.fromEntries(urlSearchParams.entries());
        return result;

        // Generate a Token by calling a method.
        // @param 1: appID
        // @param 2: serverSecret
        // @param 3: Room ID
        // @param 4: User ID
        // @param 5: Username
    const roomID = getUrlParams(window.location.href)['roomID'] || (Math.floor(Math.random() * 10000) + "");
    const userID = Math.floor(Math.random() * 10000) + "";
    const userName = "userName" + userID;
    const appID = YourAppID;
    const serverSecret = "YourServerSecret";
    const TOKEN = generatePrebuiltToken(appID, serverSecret, roomID, userID, userName);

        // You can assign different roles based on url parameters.
        let role = getUrlParams(window.location.href)['role'] || 'Host';
        role = role === 'Host' ? ZegoUIKitPrebuilt.Host : ZegoUIKitPrebuilt.Audience;
        let config = {}
        if(role === 'Host'){
            config = {
               turnOnCameraWhenJoining: true,
               showMyCameraToggleButton: true,
               showAudioVideoSettingsButton: true,
               showScreenSharingButton: true,
               showTextChat: true,
               showUserList: true,
        const zp = ZegoUIKitPrebuilt.create(TOKEN);
            container: document.querySelector("#root"),
            scenario: {
                mode: ZegoUIKitPrebuilt.LiveStreaming,
                config: {
            sharedLinks: [{
                name: 'Join as an audience',
                window.location.origin +
                window.location.pathname +
