mdreader

MD Reader — a static-hosted markdown reader/editor, served at the site root. The app
(HTML/CSS/JS) lives at the top level (index.html, css/, js/);
public share links are rendered by the serverless functions in api/. Deployed on
Vercel (static + serverless functions).

Layout

• index.html, css/, js/, images/, icons/, sounds/ — the reader app (served at /).
• manifest.webmanifest, sw.js — PWA installability + OS file handling (scoped to /).
• api/ — serverless functions: view.js (share pages at /s/{id}), share.js, sitemap.js.
• stamp-version.sh — Vercel buildCommand: stamps __BUILD__ asset URLs, minifies js/ + css/, verifies SRI pins.
• vercel.json — rewrites (/s/:id → api/view, /sitemap.xml → api/sitemap) and cache headers.

Clearing shared links

Shared links (/s/{id}) are stored one JSON blob per share in Vercel Blob under
shares/{id}.json and never expire — a share lives until it is explicitly deleted.
The store only grows, so clear it periodically.

• Delete a single share — no server access needed. Whoever created it deletes it
  from the share dialog in the app (it holds the one-time delete token). This 404s the
  page within the cache TTL.

• Bulk / owner cleanup — needs BLOB_READ_WRITE_TOKEN in the environment. Any of:

  • Vercel dashboard: Storage → your Blob store → browse shares/ → delete.

  • Vercel CLI: vercel blob ls to list, vercel blob del <url> to remove.

  • Script (delete shares older than N days, default 90):

    node scripts/clear-shares.mjs 90
