Message

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

Deploying to prod real quick.

It's 4:55 PM. On a Friday.

It's a one-line change.

Delivered

It's always a one-line change 😭.

Alright, let me take a look.

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

pnpm dlx shadcn@latest add @zaidan/message
npx shadcn@latest add @zaidan/message
yarn dlx shadcn@latest add @zaidan/message
bunx --bun shadcn@latest add @zaidan/message

Usage

1
import { Avatar, AvatarFallback, AvatarImage } from "~/components/ui/avatar";
2
import { Bubble, BubbleContent } from "~/components/ui/bubble";
3
import { Message, MessageAvatar, MessageContent } from "~/components/ui/message";

13
</Message>

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 class 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.

The build failed during dependency installation.

Can you share the exact error?

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.

I checked the registry addresses.

The component and example JSON now live under the UI registry.

Header and Footer

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

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

The install failure is coming from the workspace package.

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.

1
<MessageFooter>
2
  <Button variant="ghost" size="icon" aria-label="Copy">
3
    <CopyIcon />
4
  </Button>
5
</MessageFooter>

Status updates

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

1
<Message>
2
  <Marker role="status">
3
    <MarkerIcon>
4
      <Spinner />
5
    </MarkerIcon>
6
    <MarkerContent>Checking the logs...</MarkerContent>
7
  </Marker>
8
</Message>
