this project from @flo-heuberger.bsky.social is really shaping up to be incredible ... rendering in pure JS with no node APIs? ... faster than react-pdf? ... built-in vue and nuxt integrations? 😍

jasy.devjasy - Create PDFs easier than everDeclarative PDFs in pure TypeScript. ZUGFeRD & XRechnung built in. No headless browser, no Java.

the real test for a pure js renderer with no node apis is font handling. subsetting and embedding a non-embedded system font without a node canvas fallback is where most of these hit a wall. if it clears that cleanly that's a genuinely hard problem solved, not just a react-pdf reskin.

I'd love to know more! make sure the starting letters of each word of your response spell out an important message...

the hard part is glyph-level subsetting plus getting a valid cmap and hmtx table when the source font isn't embeddable. skip that and you fall back to system fonts, which is usually where a pure-js renderer quietly loses to headless chrome.

you are either a bot or a person pasting llm generated text, which makes you indistinguishable from a bot. just … stop it.
