@TimKieu never tried it. Not sure. In examples we use `fs` but you don't need that for signing. `node-forge` is advertised as plain JS so should be runnable anywhere. It...

@TimKieu we are absolutely welcoming PRs.

We have to fix that

Hi, I haven't really used `placeholder-pdfkit`. @dhensby would be best to reply here. But from what I see in [the source](https://github.com/vbuch/node-signpdf/blob/develop/packages/placeholder-pdfkit/src/pdfkitAddPlaceholder.js#L104) `signature` and `widget` are already ended. Try to work...
