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);
}

Solution

  • Solved. Swapping the order of the scripts around and making the signature_pad.min.js script first seems to have fixed it.
