I work a lot with generating PDF reports and what I constantly do is:

Design the pdf in illustrator / photshop
Lay it out with HTML using a library that changes from HTML to PDF (Using DOMPDF in PHP, html-pdf in nodejs, or a java parser that I can't remember its name).
Implement it in the system using the variables to be substituted, like any other view (using blade in laravel, handlebars in nodejs, and java iText in Java)
To which I wonder, is there a way to go from point 1 to point 3? In other words, export a version that can be used directly as a template. Or is there a way to optimize point 2? Stop using HTML to improve in another type of library, or a more efficient process to improve.

To make it clear, I use Spring in Java, Laravel in PHP and Express in Node js, but any help will suffice

I appreciate your help, Greetings!

PS: I don't use Python, because I work with massive amounts of data and this language is useless with it. In fact, python is useless with a lot of things that I do.
