Integrate Webcam using JavaScript step by step

First, we need to create two files index.html and style.css then we need to do code for it.

Integrate Webcam Step:1

Add below code inside index.html

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8" />
    <title>How to Integrate Webcam using JavaScript</title>
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <meta http-equiv="X-UA-Compatible" content="ie=edge" />
    <link rel="stylesheet" href="style.css" />
    <link rel="preconnect" href="https://fonts.gstatic.com">
    <link href="https://fonts.googleapis.com/css2?family=Oswald&display=swap" rel="stylesheet">
</head>

<body>
    <div class="webcam">
        <div class="video-outer">
            <video id="video" height="100%" width="100%" autoplay></video>
        </div>

        <div class="webcam-start-stop">
            <a href="#!" class="btn-start" onclick="start()">Start</a>
            <a href="#!" class="btn-stop" onclick="StopWebCam()">Stop</a>
        </div>
    </div>


    <script>
        var StopWebCam = function () {
            var stream = video.srcObject;
            var tracks = stream.getTracks();

            for (var i = 0; i < tracks.length; i++) {
                var track = tracks[i];
                track.stop();
            }
            video.srcObject = null;
        }

        var start = function () {
            var video = document.getElementById("video"),
                vendorURL = window.URL || window.webkitURL;

            if (navigator.mediaDevices.getUserMedia) {
                navigator.mediaDevices.getUserMedia({ video: true })
                    .then(function (stream) {
                        video.srcObject = stream;
                    }).catch(function (error) {
                        console.log("Something went wrong");
                    });
            }
        }
        $(function () { start(); });
    </script>
</body>

</html>

Integrate Webcam Step:2

Then we need to add code for style.css which code I provide in the below screen.

* {
  padding: 0;
  margin: 0;
  box-sizing: border-box;
  font-family: 'Oswald', sans-serif;
}
body {
  height: 100vh;
  width: 100vw;
  background: #f2f4f6;
  overflow: hidden;
}
.webcam-start-stop {
  position: fixed;
  left: 0;
  bottom: 0;
  right: 0;
  padding: 5px 0;
  background: #000;
  display: flex;
  align-items: center;
  justify-content: space-around;
}
.webcam-start-stop > a {
  text-decoration: unset;
  color: #000;
  background: #fff;
  padding: 10px 20px;
}
