What emdash-cms does

This skill walks through integrating EmDash with Astro, choosing a database and storage backend, defining content types, and fetching entries for pages. Its examples cover Cloudflare D1, SQLite on Node.js, PostgreSQL, and Turso, along with commands for schema types and database migrations.

EmDash represents rich text as Portable Text data, so pages need a renderer for that content. Its plugins run in isolated Workers; the Cloudflare setup shown here uses Worker Loaders. That configuration matters: without Worker Loaders, plugins cannot run in the sandboxed setup described by the skill.

What it helps with

  • add EmDash to an existing Astro project
  • configure a database and content storage
  • generate TypeScript definitions from a content schema
  • fetch and sort published collection entries
  • render Portable Text in an Astro page

Example prompts for the agent

  • Add EmDash to my Astro project and configure SQLite.
  • Create a content type for posts, then generate its TypeScript definitions.
  • Show me how to fetch published entries sorted by date.
