Introduction

** Hi everyone , so recently I build a full video calling application and i was stunned at how fast you can create a video calling application in just minutes using Zegocloud services.

ZEGOCLOUD basically provides powerful SDKs and UIKits that handle all the complex parts of real-time communication for you. Instead of building video streaming , device management, or connection logic from scratch, you simply design a basic Ui and integrate their APIs and your application is ready to go.

In this blog, I’ll walk you step -by-step through how to build your own video calling application using ZEGOCLOUD Step 1: Signup on Zegocloud. Here is the Link https://www.zegocloud.com/

Step 2: Click on “Create Your Project” and then click on “voice and video call” application

Step 3: Write your Project name and then click on “Start with UIKits” button

Step 4: Click on “For Web” and then click on “Save & Start to integrate”

Step 5: Get Your AppID and AppSecret from the project you created

step 6: Now Install the VS code and NodeJS application in your System if it is already installed then very good. Vs code download Link : https://code.visualstudio.com/download NodeJS Download link : https://nodejs.org/en/download step 7: Open your Vs code with a fresh new window and then create a folder on your desktop with any name and then drag and drop that folder into the center of your VS Code Application

Step 8: Open terminal and follow these steps and execute these commands one by one Here is the link to follow these commands : https://tailwindcss.com/docs/installation/using-vite

Step 9: In terminal run this command to install Zegocloud SDK and React router dom

npm install @zegocloud/zego-uikit-prebuilt react-router-dom

Step 10 : Inside src folder Create a folder with name components and create these two code files with name Home.jsx and VideoCall.jsx inside that components folder like this in the image

Step 11 : Home.jsx code. Here on this page User can create Rooms for the voice and video call

import { useState } from "react";
import { useNavigate } from "react-router-dom";

export default function Home() {
const [roomCode, setRoomCode] = useState("");
const [userName, setUserName] = useState("");
const [showRoomLink, setShowRoomLink] = useState(false);
const [generatedRoomLink, setGeneratedRoomLink] = useState("");
const [copied, setCopied] = useState(false);
const navigate = useNavigate();

const handleCreateRoom = () => {
if (userName.trim()) {
setGeneratedRoomLink(
`${window.location.origin}/room?roomID=${Math.random()
.toString(36)
.substring(2, 8)
.toUpperCase()}`
);
setShowRoomLink(true);
}
};

const copyToClipboard = () => {
navigator.clipboard.writeText(generatedRoomLink);
setCopied(true);
setTimeout(() => setCopied(false), 2000);
};

const joinCreatedRoom = () =>
navigate(
`/room?roomID=${new URLSearchParams(
new URL(generatedRoomLink).search
).get("roomID")}&userName=${userName}`
);

Step 12 : VideoCall.jsx code

import { ZegoUIKitPrebuilt } from "@zegocloud/zego-uikit-prebuilt";
import { useEffect, useRef } from "react"

function randomID(len){
let result = '';
const chars = '12345qwertyuiopasdfgh67890jklmnbvcxzMNBVCZXASDQWERTYHGFUIOLKJP';
const maxPos = chars.length
len = len || 5;
for(let i=0; i<len; i++){
result += chars.charAt(Math.floor(Math.random()*maxPos));
}
return result;
}

function getUrlParams(url = window.location.href){
let urlStr = url.split('?')[1]
return new URLSearchParams(urlStr)
}



export default function VideoCall(){
useEffect(() => {
const roomID = getUrlParams().get('roomID') || randomID(5);
const userName = getUrlParams().get('userName') || randomID(6);

if(!roomID){
window.location.href = '/'
return;
}

const UserID = randomID(5);
const appID = Number(import.meta.env.VITE_ZEGO_APP_ID);
const serverSecret = import.meta.env.VITE_ZEGO_SERVER_SECRET;
const kitToken = ZegoUIKitPrebuilt.generateKitTokenForTest(
appID ,
serverSecret,
roomID,
UserID,
userName
);
const zp = ZegoUIKitPrebuilt.create(kitToken)

zp.joinRoom({
container: meetingRef.current,
scenario : {
mode: ZegoUIKitPrebuilt.GroupCall,
},
sharedLinks: [
{
name: 'Copy Meeting Link',
url: window.location.href,
},
]
})

})

const meetingRef = useRef(null);
return(
<div ref={meetingRef}
style={{width: '100vw' , height: '100vh'}}
>

</div>
)
}

Step 13: Import this components in your App.jsx file

import { BrowserRouter, Routes , Route } from "react-router-dom";
import Home from "./components/Home";
import VideoCall from "./components/VideoCall";


export default function App(){
return(
<BrowserRouter>
<Routes>
<Route path ="/" element={<Home/>}/>
<Route path ="/room" element={<VideoCall/>}/>
</Routes>
</BrowserRouter>
)
}

Step 14: Open terminal and Run “npm run dev” and click on http://localhost:5173/

Step 15: Your application is here

Step 16 : Enter your name and click on Create New Room a new window. You will get the Room link and by using it anyone can join the video call. And to join the room just click on Jojn this Room your video call will start
