MarkdownCanDo

MarkdownCanDo is an interactive website for learning, writing, and exploring the capabilities of Markdown.

Local development

Requirements: Node.js 20 or later and pnpm 10.

pnpm install
pnpm dev

The development command detects port conflicts and automatically selects the next available port.

The production site is deployed as Cloudflare Worker Static Assets. Review the custom domain in wrangler.jsonc before deploying a fork.

pnpm cloudflare:deploy:dry

The legacy-domain redirect is maintained separately through wrangler.redirect.jsonc.
