toDataURL not working with "type: 'svg'" on the server

[mihaon]

Steps:
Execute:

console.log(await qrcode.toDataURL('I am a pony!', { type: 'svg' }))

Expected result:

data:image/svg+xml,%3Csvg%20xmlns

Actual result:

data:image/png;base64,iVBORw0K

Seems like the problem in the lib/server.js:

exports.toDataURL = function toDataURL (text, opts, cb) {
  const params = checkParams(text, opts, cb)
  const renderer = getRendererFromType(params.opts.type)
  return render(renderer.renderToDataURL, text, params)
}

Because renderer/svg.js has no renderToDataURL function.

To get around this, you can use

await qrcode.toString('I am a pony!', { type: "svg" });

which will generate an svg tag to be integrated directly into your HTML

@floriannari thanks. I use another workaround because raw SVG tags increases DOM nodes.

import qrcode from 'qrcode'

async function generateQrCode(text, options) {
	return 'data:image/svg+xml,' + encodeURIComponent(await qrcode.toString(text, {
		type: 'svg',
		...options,
	}))
}

But it would be great if the bug in the library was fixed and workarounds were not required.
