消息

The Message component lays out a single message in a conversation. It handles the avatar, alignment, header, and footer around the message surface.

For AI apps, you can render reasoning steps, tool calls and assistant messages using the Message component.

用法

import { Avatar, AvatarFallback, AvatarImage } from "@/components/ui/avatar"
import { Bubble, BubbleContent } from "@/components/ui/bubble"
import { Message, MessageAvatar, MessageContent } from "@/components/ui/message"

Use the JGuang UI Registry URL provided on /systems/jguang-ui#install.

Note: Message owns the row layout—avatar, alignment, header, and footer. Render the visible message surface inside it with Bubble. For the scroll container around a conversation, use MessageScroller.

Composition

Use the following composition to build a message:

Message
├── MessageAvatar
└── MessageContent
    ├── MessageHeader
    ├── Bubble
    └── MessageFooter

Use MessageGroup to stack consecutive messages from the same sender:

MessageGroup
├── Message
└── Message

Features

• Start and end alignment for sender and receiver rows via the align prop
• Avatar slot that anchors to the bottom of the message and stays clear of the footer
• Header and footer slots for sender names, status, and message actions
• Footer follows the message side; actions stay aligned on align="end" rows
• Group wrapper for stacking consecutive messages from the same sender
• Customizable styling through the className prop on every part

Avatar

Use MessageAvatar to render an avatar next to the message. Set align="end" on the message to align the avatar to the end of the message.

align	Description
start	Align the message to the start of the conversation.
end	Align the message to the end of the conversation.

Group

Use MessageGroup to stack consecutive messages from the same sender. Render an empty MessageAvatar on the earlier messages to keep them aligned with the avatar on the last one.

Header and Footer

Use MessageHeader for a sender name and MessageFooter for metadata such as a delivery or read status.

Actions

Place message-level actions in MessageFooter, such as copy, retry, or feedback buttons.

Attachment

Accessibility

Message is a presentational layout wrapper. Accessibility comes from the content you place inside it.

Label icon-only actions

Action buttons in MessageFooter are usually icon-only, so give each one an aria-label.

<MessageFooter>
  <Button variant="ghost" size="icon" aria-label="Copy">
    <CopyIcon />
  </Button>
</MessageFooter>

Status updates

For in-progress messages, use a Marker with role="status" so assistive tech announces the update as it appears.

<Message>
  <Marker role="status">
    <MarkerIcon>
      <Spinner />
    </MarkerIcon>
    <MarkerContent>Checking the logs...</MarkerContent>
  </Marker>
</Message>
