Hi there,

I'm trying to use this module without nodejs, but I'm getting an error telling me PdfContext is undefined. Here is my code for reference:

(index.html)

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

<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
    <script src="blob-stream.js"></script>
    <script src="file-saver.min.js"></script>
    <script src="canvas2pdf.min.js"></script>
    <script src="./index.js"></script>
</head>

<body>
...
</body>

</html>

The file canvas2pdf.min.js above is the /dist/canvas2pdf.js file

(index.js)

// Create a new PDF canvas context.
const ctxPdf = new PdfContext(blobStream());

// draw your canvas like you would normally
ctxPdf.fillStyle = "yellow";
ctxPdf.fillRect(100, 100, 100, 100);
// more canvas drawing, etc...

// convert your PDF to a Blob and save to file
ctxPdf.stream.on("finish", function () {
  var blob = ctxPdf.stream.toBlob("application/pdf");
  saveAs(blob, "example.pdf", true);
});
ctxPdf.end();

And this is the error the browser is throwing Uncaught ReferenceError: PdfContext is not defined

Any idea what I'm doing wrong?

I would suggest using a build tool (e.g https://github.com/joshua-gould/canvas2pdf/blob/master/package.json#L27)
