Citations
A React component in Beamline's AI & agents category.
Inline numbered citations that preview their source on hover or focus, plus a numbered source list; streamed answers flow in at an even pace with the list waiting for the end.
Use it for
- Agent answers grounded in documents, tickets or web pages.
Not for
- Showing retrieved chunks in full (context-cards).
- Long markdown answers (response).
Anatomy
- text
- citation marker (link; keeps trailing punctuation on its line)
- source preview (domain, kind, title, snippet)
- source list
Variants
- list: on, off
States
- streaming (words ease in once; list waits)
- settled
- marker without a source (plain text)
- hover/focus preview
Keyboard
- Markers are links; focus opens the preview, Escape closes it.
Motion
Preview uses hover-card timing; streamed words fade in from a slight blur over --duration-considered, never again once shown; streamed text wraps greedily and the newest word's trailing space waits for the next word, so no line re-breaks; none under reduced motion.
