# Conversation history

A React block (a whole screen) in [Beamline](https://beamline.io/)'s [Blocks](https://beamline.io/components/blocks) category. Live demo: https://beamline.io/components/conversation-history

Past conversations with an assistant, ready to pick up again: the list by day with bookmarks and unsent drafts, a search through every message that groups hits by conversation and lands on the exact message, a link to a conversation or to one message that reopens it there, an interrupted answer with Continue, and a composer whose draft stays with its conversation when you open another.

## Use it for

- The history page of an AI assistant: find an old answer, reopen it from a link or a bookmark, carry on.
- Any product where people return to long threads and need to land on one message (support transcripts, research).

## Not for

- Talking to the assistant now ([agent-workspace](https://beamline.io/components/agent-workspace) or [support-chat](https://beamline.io/components/support-chat)).
- Triaging incoming conversations that wait for a person ([inbox-list](https://beamline.io/components/inbox-list), [support-console](https://beamline.io/components/support-console)).
- Team channels ([team-chat](https://beamline.io/components/team-chat)).

## Anatomy

- list column: title and New chat, search, All or Bookmarked with counts, conversations grouped by day (Today, Yesterday, This week, This month, Earlier) with title, bookmark, model, message count and age; a conversation with an unsent draft shows the draft instead
- search results: how many messages in how many conversations, then per conversation its title and each hit as a snippet with the matched words marked, who said it
- conversation: title, model and age, the matches here (2 of 5, previous and next), Bookmark, Copy link; the turns, each with its age and Copy link to this message; an interrupted answer says so with Continue
- composer: continue the conversation; the draft is kept per conversation

## Variants

- **0**: room: list and conversation side by side from 48rem; below that one at a time with a way back

## States

- loading the list; loading one conversation (opened from a cold link)
- nothing open (pick up where you left off)
- landed on a message (it is centred and a tint fades from it once)
- search with hits; search with no hits
- no bookmarks yet; no conversations yet
- a link to a conversation that is gone (deleted or not shared)
- an answer that stopped before it finished (Continue)
- a draft kept in another conversation
- A pending send accepts one submission; its acknowledgement clears only that unchanged draft and preserves newer drafts in every conversation.

## Keyboard

- Tab: New chat, search, All or Bookmarked, the conversations or the hits, then the conversation's actions and composer
- Enter on a row or a hit opens it and lands on its message
- Enter sends, Shift+Enter breaks the line

## Motion

The open conversation's plate travels between rows; a message landed on by a link or a hit is lit and fades over a second and a half (held, not animated, under reduced motion); hits rise in as they appear. Nothing moves at rest.

## Props

| `target / defaultTarget / onTargetChange` | `{ threadId, messageId? } \| null` | — | The open conversation and the message to land on; put it in the address to make links work. |
| `query / defaultQuery / onQueryChange` | `string` | — |  |
