web worker throwing 404 when executing

My project structure looks like

js/
  /client.js
  /script1.js
  /webWoker.js

The main.html has it included as well in

<script type="text/javascript" src="js/script1.js"></script>
<script type="text/javascript" src="js/client.js"></script>
<script type="text/javascript" src="js/webWoker.js"></script>

My script1.js looks like

var myWorker = new Worker("webWorker.js");

        if (window.Worker) {
            myWorker.onmessage = function (e) {
                result.textContent = e.data;
                console.log('Message received from worker: ' + result.textContent);
            };
        }

and my webWorker.js looks like

onmessage = function (e) {
    console.log('Message received from main script');
    var result = "#27ae60";
    console.log('Posting message back to main script');
    postMessage(result);
};

I use node.js for this project and run it via npm start, and when I run this in browser I see

script1.js:81 GET http://localhost:8080/webWorker.js 404 (Not Found)
execute @ script1.js:81
img.onload @ script1.js:64

What is going wrong here?
