I’m trying to convert XML data into PDF files from a web page and I was hoping I could do this entirely within JavaScript. I need to be able to draw text, images and simple shapes. I would love to be able to do this entirely in the browser.
This question is related to
javascript

pdf-generation
You can use this free service by adding a link which creates pdf from any url (e.g. http://www.phys.org):
Another interesting project is texlive.js.
It allows you to compile (La)TeX to PDF in the browser.
Even if you could generate the PDF in-memory in JavaScript, you would still have the issue of how to transfer that data to the user. It's hard for JavaScript to just push a file at the user.
To get the file to the user, you would want to do a server submit in order to get the browser to bring up the save dialog.
With that said, it really isn't too hard to generate PDFs. Just read the spec.
Another javascript library worth mentioning is pdfmake.
The browser support does not appear to be as strong as jsPDF, nor does there seem to be an option for shapes, but the options for formatting text are more advanced then the options currently available in jsPDF.
I maintain PDFKit, which also powers pdfmake (already mentioned here). It works in both Node and the browser, and supports a bunch of stuff that other libraries do not:
Check out http://pdfkit.org/ for a full tutorial to see for yourself what PDFKit can do. And for an example of what kinds of documents can be produced, check out the docs as a PDF generated from some Markdown files using PDFKit itself: http://pdfkit.org/docs/guide.pdf.
You can also try it out interactively in the browser here: http://pdfkit.org/demo/browser.html.
