Embed

learning · static (no JavaScript) · no children. All components: component playground.

Description for the model

External media by URL (YouTube, Vimeo); other URLs become a link card.

Live example

Rendered from the example props below with the real component. Theme: coffee · oncall · nightsky · gravity · poland · ulam · platform · open on its own

Example

{
  "component": "Embed",
  "props": {
    "url": "https://example.org/embed/grind-size",
    "title": "Grind size visualiser"
  }
}

Props

Prop	Type	Required	Notes
url	string (href)	yes	Media URL. max length 2048
title	string	yes	Title. max length 160
id	string		Anchor id for in-page links (letters, digits, dashes). max length 40

Text fallback

What a text-only client, an unknown renderer or a plain-text channel shows for the example above.

Grind size visualiser: https://example.org/embed/grind-size

Invalid props

A node whose props fail the schema never breaks the page: the renderer shows the plain-text fallback instead (and logs the issues in development).

{
  "url": "javascript:alert(1)",
  "title": "Unsafe"
}

Issues:

• /url unsafe or empty link

Rendered as:

Unsafe: javascript:alert(1)
