Blog subdomain, plus a clean Mermaid renderer

blog.makespdf.com is live, served from the same Worker. Under the hood, the Mermaid pipeline was rewritten as @pdf/mermaid-render — 80% smaller SVG, no fake DOM, Workers-native.

Two things shipped together because they wanted each other.

The blog is now served from a dedicated subdomain with its own routing, while still living inside the same Cloudflare Worker as the rest of the app. Posts are markdown files in apps/web/content/blog/; each one is also available as a download-ready PDF rendered by the same engine that powers the public API.

@pdf/mermaid-render

The Mermaid → SVG pipeline was rewritten end-to-end. The old approach pulled in mermaid + linkedom (76.5 MB installed) and depended on a fake DOM; the new package is a clean parse → layout → render pipeline:

  • Vendored jison parsers from Mermaid v11.12.2 produce typed ASTs.
  • ELK.js computes graph layout for flowchart / class / state / ER.
  • SVG XML is generated directly — no DOM, no shim.
  • Single external dependency: elkjs.

Result: 7.7 MB installed (down from 76.5 MB), SVG output ~80% smaller (3 KB vs 15 KB), deterministic, Workers-compatible. Supports all 8 Mermaid diagram types: flowchart (with subgraphs), sequence, class, state, gantt, pie, ER, gitgraph.
