3.0.8 breaks require("canvg")

[shanebdavis]

3.0.7 works with require("canvg")

(NodeJS v14.17.0; NPM v7.6.0)

I understand there is a desire to move towards ES modules, but 3.0.8 was a patch update; it shouldn't cause breaking changes. If such a breaking change is needed to further ES-module support, that should be a major version change e.g. 4.0.0.

I'd like to request a 3.0.9 release that restores CommonJS compatibility and a 4.0.0 release with the new ES-module changes.

@shanebdavis can you try canvg@3.0.9 ?

3.0.9 still appears broken to me. 3.0.7 works perfectly (I use canvg as part of a process to download an SVG as an image) but 3.0.8 and 3.0.9 both only produce a blank white image. Honestly I'm not sure what issues it's related to and am happy to open a new issue certainly, but it appears to me likely related to 3.0.8 generally being a patch-release-regression and I'm not sure what, if anything, makes my setup unique. I use Canvg in the import Canvg from 'canvg'; style, but I use it in a web application so it makes me think that perhaps this is related to changing the type of the package as 3.0.8 did. I have no errors in my console nor when webpacking, it just downloads a blank image.

@Jason-Morcos Hi. Can you provide example of SVG?

[Jason-Morcos]

Hi @dangreen, thank you for the reply!
The SVG is inline rendered within html so I did the best I could (copied into vs code and saved as SVG). I also included the png shown from downloading via the browser (browser-side JS calling canvg). The image download does work still with 3.0.7 so we've reverted production to that release, but I'm happy to keep trying each new version/any possible fix version to see if it's resolved and to try to garner any additional debug info as needed.

Extracted SVG:

@Jason-Morcos I can't reproduce this issue: on demo page all works fine

Can you please provide minimal repo with reproduction?
