Message

Displays a message in a conversation, with optional avatar, header, footer, and alignment.

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.

Installation

import {
  Message,
  MessageGroup,
} from "@o/pipeline/experimental/components/chat/message";

Usage

import { Avatar } from "@o/pipeline/experimental/components/avatar";
import { Bubble } from "@o/pipeline/experimental/components/chat/bubble";
import { Message } from "@o/pipeline/experimental/components/chat/message";

<Message.Root>
  <Message.Avatar>
    <Avatar.Root>
      <Avatar.Image src="https://github.com/shadcn.png" alt="@shadcn" />
      <Avatar.Fallback>CN</Avatar.Fallback>
    </Avatar.Root>
  </Message.Avatar>
  <Message.Content>
    <Bubble.Root>
      <Bubble.Content>How can I help you today?</Bubble.Content>
    </Bubble.Root>
  </Message.Content>
</Message.Root>

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.Root
├── Message.Avatar
└── Message.Content
    ├── Message.Header
    ├── Bubble.Root
    └── Message.Footer

Use MessageGroup to stack consecutive messages from the same sender:

MessageGroup
├── Message.Root
└── Message.Root

Features

• Start and end alignment for sender and receiver rows via the align prop
• Avatar slot that anchors to the top of the message
• 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 Message.Avatar to render an avatar next to the message. Set align="end" on the message to align the avatar to the end of the message.

Group

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

Header and Footer

Use Message.Header for a sender name and Message.Footer for metadata such as a delivery or read status. Every message reserves the footer band a small gap below its bubble, so scroller rows stay evenly spaced even when no footer is rendered.

Actions

Place message-level actions in Message.Footer, such as copy, retry, or feedback buttons. Use Button for icon-only actions.

Attachment

Render file and image attachments inside Message.Content with Attachment.

Thanks. Looks good.

Accessibility

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

Label icon-only actions

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

<Message.Footer>
  <Button variant="ghost" size="sm" icon aria-label="Copy">
    <IconCopy />
  </Button>
</Message.Footer>

Status updates

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

import { Marker } from "@o/pipeline/experimental/components/chat/marker";
import { Spinner } from "@o/pipeline/experimental/components/spinner";

<Message.Root>
  <Marker.Root role="status">
    <Marker.Icon>
      <Spinner />
    </Marker.Icon>
    <Marker.Content>Checking the logs...</Marker.Content>
  </Marker.Root>
</Message.Root>;
