This worker adds server-rendered Open Graph metadata and dynamic PNG preview cards to the link.pythonide.xin Cloudflare Pages site. It only reads the restricted Community V2 public projections and intercepts the AASA endpoint, /s/*, /community/*, and /og/*.

Cloudflare Pages advanced mode is the production owner. link-site/_worker.js re-exports this module from the published edge/ directory. When the Pages ASSETS binding is present, it reads the share template from the local Pages deployment and forwards all non-edge routes (including the public OAuth metadata and callback pages) to the static asset service. This permits the link.pythonide.xin subdomain to use an external-DNS CNAME without moving the pythonide.xin nameservers.

Community V2 posts use /community/{postID}. Stable creator profiles use /community/user/{userID} rather than mutable handles. Both routes fetch only the corresponding public V2 representation at request time; no community content or user record is committed to this repository.

The AASA route serves the reviewed association document directly with an application/json content type. Keep it semantically equivalent to ../link-site/.well-known/apple-app-site-association; the worker test enforces that contract before deployment.

The worker fetches the published index.html from the pythonide-link repository, reads public work details from GET /v2/community/works/:scriptID/share, and replaces the edge:meta block before returning the page. That projection never contains a project package URL, OSS key, or complete ZIP. Social crawlers such as WeChat therefore receive the work title and description without executing JavaScript.

Run npm test before deploying. Use scripts/deploy_link_pages.sh after authenticating the Cloudflare account that owns the pythonide-link Pages project. Do not deploy this module as a separate routed Worker.
