What is vmprint?

vmprint is a pure-JS, zero-dependency TypeScript typesetting engine that generates bit-perfect PDF output across any runtime—from Cloudflare Workers to the browser. It takes structured JSON documents or Markdown input and handles precise layout, pagination, multilingual text shaping, and tables, producing identical results every time. Stop using headless Chrome or heavy libraries to print text; this core-js pure GitHub tool delivers deterministic PDFs without Node.js or DOM assumptions.

Why is it gaining traction?

Unlike Puppeteer or PDFKit, which force manual pagination or drift across environments, vmprint separates layout into a diffable JSON stream you can snapshot for tests, then renders to PDF (or future SVG/canvas). Its 88 KiB core crushes complex docs in milliseconds on edge runtimes, with CLI flags like `--emit-layout` for inspection and `--render-from-layout` for caching. Multilingual support—from CJK justification to partial RTL—ensures pro-grade output without compromises.

Who should use this?

Backend devs building serverless PDF APIs on Cloudflare or Lambda, who hate Chrome's cold starts and memory hogs. Docs teams generating open-source readmes, academic papers, or screenplays from Markdown via the draft2final CLI. Anyone needing reproducible typesetting for reports, invoices, or books without LaTeX hassle.

Verdict

Grab it for edge PDF gen now—CLI and API are solid for prototypes—but at 95 stars and 1.0% credibility, treat as pre-1.0 alpha with good regression tests. Watch for full bidi and more formats.
