I am currently using weasyprint to convert a HTML template to pdf. Now my company has decided to move from python to javascript for increased user experience or something. Is there a PDF renderer in JavaScript that can do the following:

• Use data on the client. I have data that under no circumstances can be transferred over the internet. (That is the reason I can not create the pdf on backend side or use external renderers.)
• Use CSS page numbering
• Use features like page headers and footers on print medium.
• And of course can do the usual CSS layout.

Ideally there is something that can be used in python and javascript. But Weasyprint works great with python, so I can keep that if there is no "one tool to do the job everywhere".
