API reference

SupportWidget

A help launcher that grows into article search, an article reader and a chat thread. Articles, team and suggested replies are sample data in support-widget-data.ts; agent replies are simulated.

PropTypeDefaultDescription
onSend(message: string) => void–Called with each message the person sends, so you can forward it to your inbox or chat provider.
onOpenChange(open: boolean) => void–Called when the launcher opens or closes the panel.

Keyboard interactions

Escape
Closes the panel and returns focus to the launcher.
Arrow down
From the search field, moves focus into the article list.
Arrow uporArrow down
Moves between articles; up from the first article returns to search.
Enter
In search, opens the top result.

Accessibility

  • The open panel is a role="dialog" whose label switches between Help and the conversation.
  • The chat thread is a role="log" with a screen reader only typing indicator, and a polite live region announces view changes.
  • The launcher uses aria-haspopup="dialog" and includes the unread reply count in its label.

Motion

  • The launcher springs open into the panel, and views slide in the direction of travel.
  • Unread badges and the launcher icon pop in on a snappy spring; changing text crossfades with a short rise.
  • Reduced motion replaces scale, slide and rotate with plain fades.

Responsive behavior

  • The dock is positioned absolute inside the block's 680px demo stage; move it to position fixed when you mount it in a real app.
  • Below a 519px container the stage is 640px tall, the dock sits closer to the corner, and the sample app nav hides.
  • On coarse pointers opening chat focuses the panel instead of the text field, so the keyboard does not pop up on its own.

Performance

  • Views mount one at a time and ResizeObservers animate the panel size between them.
  • Article search filters an in-memory list; move it to your search API for a large help center.

Notes for AI

Give your coding assistant the Markdown reference instead of screenshots.

  • Use as the in-app help entry point of a SaaS product, mounted once near the app root.
  • Replace ARTICLES, TEAM, SUGGESTIONS and replyTo in support-widget-data.ts with your help center and real replies.
  • Wire onSend to your inbox or chat provider; the sample app page behind the launcher is decoration to remove.
