@bradmartin @burkeholland I would appreciate if you can take a look at this PR and if possible to merge and release a new version to npm.

Thanks @VladimirAmiorkov! This is now merged and published.

Just fyi npm run pack froze for me when copying the src folder, which was a bit odd. When I ran the pack and publish scripts manually though everything worked fine. No big deal, but I thought I’d note that for future reference.

Hi @tjvantoll ,

Thank you. I will take a look at the npm run pack command I have not used it also so I will fix it.
