Using unpdf to convert a PDF graphic to SVG

[dmca-glasgow]

Hi there 👋

Thanks for all the great open-source packages!

I've been struggling to ressurect some old code to convert PDF graphics to SVG in node.js using pdfjs:

import * as pdfjsLib from 'pdfjs-dist/legacy/build/pdf';

export async function pdfToSvg(filePath: string) {
  const doc = await pdfjsLib.getDocument({
    url: filePath,
    fontExtraProperties: true,
    verbosity: 0,
  });

  const page = await doc.getPage(1);
  const opList = await page.getOperatorList();
  const viewport = page.getViewport({ scale: 1.0 });
  const svgGfx = new pdfjsLib.SVGGraphics(page.commonObjs, page.objs);
  svgGfx.embedFonts = true;
  return svgGfx.getSVG(opList, viewport);
}

The error I currently have is:

TypeError: doc.getPage is not a function

I believe my error relates to require vs. import but really not sure as there are no other errors...

I've tried with unpdf:

import { definePDFJSModule, getResolvedPDFJS } from 'unpdf';

await definePDFJSModule(() => import('pdfjs-dist/legacy/build/pdf.mjs'));
const { getDocument } = await getResolvedPDFJS();
const data = await readFile(filePath);
const doc = await getDocument({
  data: new Uint8Array(data),
  fontExtraProperties: true,
  // verbosity: 0,
}).promise;

console.log(doc)

But my console.log never prints, and there are no errors...

Any suggestions most appreciated!
