How can I start using dwv (DICOM Web Viewer) on my website?

I’m new to JavaScript.

To view DICOM images I want to use this DICOM Web Viewer by ivmartel:

https://github.com/ivmartel/dwv

I have downloaded it and installed it using YARN. I can test run it using yarn run test.

But how can I implement it on my website?

I just wanted to use it here:

https://ivmartel.github.io/dwv/doc/stable/tutorial-examples.html

I just copied the codes existing here:

https://jsfiddle.net/ivmartel/kkp7ytk3/

But it looks like it can’t import dwv at all.

Code of my page looks like this:

<!DOCTYPE html>
<html>
 
<head>
    <script src="http://code.jquery.com/jquery-2.1.0.min.js"></script>
    <script src="dwv-develop/src/app/application.js"></script>
    <title>
        JavaScript to check existence of variable
    </title>
</head>
         
<body>        
    <div id="dwv">
        <div id="layerGroup0"></div>
      </div>
      
    <script>
        var app = new dwv.App();
        // initialise with the id of the container div
        app.init({
        dataViewConfigs: {'*': [{divId: 'layerGroup0'}]},
        tools : {
            WindowLevel: {}
        } // or try "ZoomAndPan"
        });
        // activate tool once done loading
        app.addEventListener('load', function () {
        app.setTool('WindowLevel');
        });
        // load dicom data
        app.loadURLs(['https://raw.githubusercontent.com/ivmartel/dwv/master/tests/data/bbmri-53323851.dcm']);// create the dwv app
    </script>
</body>
 
</html>   

How can I import dwv to make it work on my website?
