@openuidev/react-ui

API reference for prebuilt chat layouts and default component library exports.

Use this package for prebuilt chat UIs and default component library primitives.

Import

import { Copilot, FullScreen, BottomTray } from "@openuidev/react-ui";

Layout components

These layouts are documented in Chat UI guides and are all wrapped with ChatProvider.

Copilot

Sidebar chat layout.

type CopilotProps = ChatLayoutProps;

FullScreen

Full-page chat layout with thread sidebar.

type FullScreenProps = ChatLayoutProps;

BottomTray

Floating/collapsible tray layout.

type BottomTrayProps = ChatLayoutProps & {
  isOpen?: boolean;
  onOpenChange?: (isOpen: boolean) => void;
  defaultOpen?: boolean;
};

Shared layout props (ChatLayoutProps)

All three layouts accept:

  • Chat provider props: apiUrl/processMessage, thread APIs, streamProtocol, messageFormat
  • Shared UI props:
    • logoUrl?: string
    • agentName?: string
    • messageLoading?: React.ComponentType
    • scrollVariant?: ScrollVariant
    • isArtifactActive?: boolean
    • renderArtifact?: () => React.ReactNode
    • welcomeMessage?: WelcomeMessageConfig
    • conversationStarters?: ConversationStartersConfig
    • assistantMessage?: AssistantMessageComponent
    • userMessage?: UserMessageComponent
    • composer?: ComposerComponent
    • componentLibrary?: Library (from @openuidev/react-lang)
  • Theme wrapper props:
    • theme?: ThemeProps
    • disableThemeProvider?: boolean

UI customization types

Types used by customization docs:

type AssistantMessageComponent = React.ComponentType<{ message: AssistantMessage }>;
type UserMessageComponent = React.ComponentType<{ message: UserMessage }>;

type ComposerProps = {
  onSend: (message: string) => void;
  onCancel: () => void;
  isRunning: boolean;
  isLoadingMessages: boolean;
};
type ComposerComponent = React.ComponentType<ComposerProps>;

type WelcomeMessageConfig =
  | React.ComponentType<any>
  | {
      title?: string;
      description?: string;
      image?: { url: string } | React.ReactNode;
    };

interface ConversationStartersConfig {
  variant?: "short" | "long";
  options: ConversationStarterProps[];
}

Component library exports

Two ready-to-use libraries ship with @openuidev/react-ui. Import from the genui-lib subpath:

import {
  // Chat-optimised (root = Card, includes FollowUpBlock, ListBlock, SectionBlock)
  openuiChatLibrary,
  openuiChatPromptOptions,
  openuiChatExamples,
  openuiChatAdditionalRules,
  openuiChatComponentGroups,

  // General-purpose (root = Stack, full component suite)
  openuiLibrary,
  openuiPromptOptions,
  openuiExamples,
  openuiAdditionalRules,
  openuiComponentGroups,
} from "@openuidev/react-ui/genui-lib";

openuiChatLibrary — Root is Card (vertical, no layout params). Includes chat-specific components: FollowUpBlock, ListBlock, SectionBlock. Does not include Stack. Use with FullScreen / BottomTray / Copilot chat interfaces.

openuiLibrary — Root is Stack. Full layout suite with Stack, Tabs, Carousel, Accordion, Modal, etc. Use with the standalone Renderer or any non-chat layout (e.g., playground, embedded widgets, dashboards).

openuiPromptOptions — includes examples and additional rules for the general-purpose library. Does not include toolExamples — pass those in your app-level PromptSpec alongside tool descriptions.

Generate the system prompt at build time with the CLI:

npx @openuidev/cli@latest generate ./src/library.ts --out src/generated/system-prompt.txt
// Chat interface — system prompt stays on the server
<FullScreen componentLibrary={openuiChatLibrary} ... />

// Standalone renderer
<Renderer response={message} library={openuiLibrary} />

Skeleton components

Skeleton and TableSkeleton are loading-state placeholders that render while data-driven genui components wait for Query() results. They use theme-aware CSS variables and a pulsing opacity animation.

import { Skeleton, TableSkeleton } from "@openuidev/react-ui";

Skeleton

A generic skeleton bar. Use standalone or with count for stacked bars.

PropTypeDefaultDescription
countnumber1Number of bars to stack
heightstring"16px"Bar height
widthstring"100%"Bar width
borderRadiusstringundefinedBar border radius (defaults to --openui-radius-xs)

TableSkeleton

A table-shaped placeholder used by the genui Table component while queries load.

PropTypeDefaultDescription
rowsnumber5Number of skeleton rows
columnsnumber4Number of skeleton columns

Built-in genui components like Table automatically render TableSkeleton when useIsQueryLoading() is true and no data rows exist yet.
