Cards

Rich card components for cross-platform interactive messages.

Card components render natively on each platform — Block Kit on Slack, Adaptive Cards on Teams, Embeds on Discord, and Google Chat Cards.

import { Card, Text, CardLink, Button, Actions, Section, Fields, Field, Divider, Image, LinkButton, Table } from "chat";

All components support both function-call and JSX syntax. Function-call syntax is recommended for better type inference.

Card

Top-level container for a rich message.

Card({
  title: "Order #1234",
  subtitle: "Pending approval",
  children: [Text("Total: $50.00")],
})

Prop

Type

Text

Text content element. Use CardText instead of Text in JSX to avoid conflicts with React's built-in types.

Text("Hello, world!")
Text("Important", { style: "bold" })
Text("Subtle note", { style: "muted" })

Prop

Type

Button

Interactive button that triggers an onAction handler.

Button({ id: "approve", label: "Approve", style: "primary" })
Button({ id: "delete", label: "Delete", style: "danger", value: "item-123" })

Prop

Type

Inline hyperlink rendered as text. Can be placed directly in a card alongside other content, unlike LinkButton which must live inside Actions.

CardLink({ url: "https://example.com", label: "Visit Site" })

Prop

Type

LinkButton

Button that opens a URL. No onAction handler needed.

LinkButton({ url: "https://example.com", label: "View Docs" })

Prop

Type

Actions

Container for buttons and interactive elements. Required wrapper around Button, LinkButton, Select, and RadioSelect.

Actions([
  Button({ id: "approve", label: "Approve", style: "primary" }),
  Button({ id: "reject", label: "Reject", style: "danger" }),
  LinkButton({ url: "https://example.com", label: "View" }),
])

Section

Groups related content together.

Section([
  Text("Grouped content"),
  Image({ url: "https://example.com/photo.png" }),
])

Fields

Renders key-value pairs in a compact, multi-column layout.

Fields([
  Field({ label: "Name", value: "Jane Smith" }),
  Field({ label: "Role", value: "Engineer" }),
])

Field

A single key-value pair. Must be used inside Fields.

Prop

Type

Image

Embeds an image in the card.

Image({ url: "https://example.com/screenshot.png", alt: "Screenshot" })

Prop

Type

Table

Structured data display with column headers and rows.

Table({
  headers: ["Name", "Age", "Role"],
  rows: [
    ["Alice", "30", "Engineer"],
    ["Bob", "25", "Designer"],
  ],
})

Prop

Type

On platforms with native table support (Teams, GitHub, Linear), tables render as formatted tables. On other platforms (Slack, Google Chat, Discord, Telegram), tables render as padded ASCII text.

Divider

A visual separator between sections.

Divider()

CardChild types

The children array in Card and Section accepts these element types:

TypeCreated by
TextElementText()
LinkElementCardLink()

ActionsElementActions()
