How do I start video streaming using webRTC?

I am writing the following code for starting my camera and watch my video on the Google Chrome browser using the technology webRTC. There are two files I have created index.html and client.js. I have attached the code of both. Node.js server is installed on my PC. The problem is my camera is switching on but I am unable to see the video streaming.

client.js

function hasUserMedia() { 
   //check if the browser supports the WebRTC 
   return !!(navigator.getUserMedia || navigator.webkitGetUserMedia || 
      navigator.mozGetUserMedia); 
} 

if (hasUserMedia()) { 
   navigator.getUserMedia = navigator.getUserMedia || navigator.webkitGetUserMedia
      || navigator.mozGetUserMedia; 

   //enabling video and audio channels 
   navigator.getUserMedia({ video: true, audio: true }, function (stream) { 
      var video = document.querySelector('video'); 

      //inserting our stream to the video tag     
      video.src = window.URL.createObjectURL(stream); 
   }, function (err) {}); 
} else { 
   alert("WebRTC is not supported"); 
}`

index.html

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

   <head> 
      <meta charset = "utf-8" /> 
       <link rel="stylesheet" href="css/main.css" />
   </head> 

   <body> 
      <video autoplay></video>
      <script src = "js/client.js"></script>     
   </body>
    </html>
