SignaturePad not defined - can not initialise signature_pad module into script

I'm having an issue using the npm module - signature_pad, and can't seem to get it set up. At the moment all I am using is vanilla HTML, CSS and JS. At the moment I keep getting an error saying: SignaturePad is not defined. I tried importing the module from my package.JSON file using import SignaturePad from 'signature_pad' but I get an error back saying unexpected token import.

I have attached my HTML and JS code below. Any suggestions?

JavaScript

    var wrapper1 = document.getElementById("signature-pad-1"),
        canvas1 = wrapper1.querySelector("canvas"),
        signaturePad1;

        resizeCanvas(canvas1);
        signaturePad1 = new SignaturePad(canvas1);

        function resizeCanvas(canvas) {
           var ratio =  window.devicePixelRatio || 1;
           canvas.width = canvas.offsetWidth * ratio;
           canvas.height = canvas.offsetHeight * ratio;
           canvas.getContext("2d").scale(ratio, ratio);
       }

HTML

    <!DOCTYPE html>
    <html>
      <head>
        <meta charset="utf-8">
        <title>Sign Here</title>
        <link rel="stylesheet" href="main.css">
      </head>
      <body>
        <div class="contract">
          <h1>Signature Below</h1>
          <p>ABC</p>
          <div id="signature-pad-1" class="m-signature-pad">
            <div class="m-signature-pad--body">
              <canvas></canvas>
            </div>
          </div>
          <script type="text/javascript" src="./js/sig_pad.js"></script>
          <script src="https://cdnjs.cloudflare.com/ajax/libs/signature_pad/1.5.3/signature_pad.min.js"></script>
      </body>
    </html>
