Cloudflare Worker that injects dynamic og:title, og:description, og:image, and og:url into the atbbs SPA for link previews on social platforms.

Handles two route patterns:

/bbs/* — rewrites the HTML <meta> tags with BBS/board/thread metadata from Slingshot
/og/bbs/*.png — generates a branded 1200x630 preview image on the fly

Deploy #

cd opengraph
npm install
npx wrangler login
npx wrangler deploy -c wrangler.toml

Requires atbbs.xyz to be proxied through Cloudflare.
