Editor

Try the editor

A live RichTextEditor. The document loads from Markdown at theuntrusted tier, and the Markdown it saves as updates below it. It follows this site's light or dark mode; the editor has no motion to reduce.

• Ctrl or Cmd + B, I: bold, italic
• Ctrl or Cmd + K: edit a link; an unsafe address such as javascript: is refused with a visible error
• Ctrl or Cmd + Z, and with Shift: undo, redo
• Tab: indent a list item; Escape, then Tab: leave the editor

const greeting = 'hello';

Nodes and marks

The vocabulary is closed: anything else in pasted HTML or loaded Markdown degrades to text with a diagnostic. Nothing renders through an HTML sink.

In the builder

The blueprint builder edits the Markdown fields of text blocks (text, quote and callout body) with this editor. The field still stores Markdown: the editor reads it, reports what it could not keep, and writes the Markdown back on each edit. Text edits join one labeled undo step in the builder history, and Ctrl or Cmd +Z inside the editor undoes text first.

Examples

• Rich text editor
• Editor with toolbar and links
• Long document editing

What ships

• One labelled multiline textbox; every edit becomes a model transform, and input methods are diffed into one step.
• A roving formatting toolbar with pressed states and shortcuts.
• A link dialog that checks addresses with safeHref (untrusted by default).
• Snapshot undo and redo, announced politely.
• Paste as data: an owned HTML tokenizer and allowlist, every pasted link checked at the untrusted tier.
• Markdown in and out, the same subset text blocks and the catalog's rich text parse.

Planned

• Copy in the editor's own JSON format, and drop.
• A block-type menu, drag handles and a “Paste as Markdown” command.
• A browser behavior scenario, an axe sweep and measured long-document limits for the editor package.
• The editor on list items in the builder (each item is a plain text field today).
