CDN Usage

You can also use this library directly in the browser via CDN:

Option 1: With JSX Support (using Babel)

<!DOCTYPE html>
<html>
  <head>
    <!-- Load React -->
    <script
      crossorigin
      src="https://unpkg.com/react@18/umd/react.production.min.js"
    ></script>
    <script
      crossorigin
      src="https://unpkg.com/react-dom@18/umd/react-dom.production.min.js"
    ></script>

    <!-- Load Babel Standalone for JSX processing -->
    <script src="https://unpkg.com/@babel/standalone@7.23.6/babel.min.js"></script>

    <!-- Manually create the jsxRuntime object to satisfy the dependency -->
    <script>
      // Provide a minimal JSX runtime for builds that expect react/jsx-runtime globals.
      const withKey = (props, key) =>
        key == null ? props : Object.assign({}, props, { key });
      const jsx = (type, props, key) =>
        React.createElement(type, withKey(props, key));
      const jsxRuntime = {
        Fragment: React.Fragment,
        jsx,
        jsxs: jsx,
        jsxDEV: jsx,
      };

      window.ReactJSXRuntime = jsxRuntime;
      window['react/jsx-runtime'] = jsxRuntime;
      window['react/jsx-dev-runtime'] = jsxRuntime;
    </script>

    <!-- Load the webui library -->
    <script src="https://unpkg.com/@qwen-code/webui@0.1.0-beta.2/dist/index.umd.js"></script>

    <!-- Load the CSS -->
    <link
      rel="stylesheet"
      href="https://unpkg.com/@qwen-code/webui@0.1.0-beta.2/dist/styles.css"
    />
  </head>
  <body>
    <div id="root"></div>

    <script type="text/babel">
      // Access components from the global QwenCodeWebUI object
      const { ChatViewer } = QwenCodeWebUI;

      // Use the components with JSX support
      const App = () => (
        <ChatViewer messages={/* your messages */} />
      );

      ReactDOM.render(<App />, document.getElementById('root'));
    </script>
  </body>
</html>

Option 2: Without JSX (using React.createElement directly)

<!DOCTYPE html>
<html>
  <head>
    <!-- Load React -->
    <script
      crossorigin
      src="https://unpkg.com/react@18/umd/react.production.min.js"

      src="https://unpkg.com/react-dom@18/umd/react-dom.production.min.js"
    ></script>

    <!-- Manually create the jsxRuntime object to satisfy the dependency -->
    <script>
      // Provide a minimal JSX runtime for builds that expect react/jsx-runtime globals.
      const withKey = (props, key) =>
        key == null ? props : Object.assign({}, props, { key });
      const jsx = (type, props, key) =>
        React.createElement(type, withKey(props, key));
      const jsxRuntime = {
        Fragment: React.Fragment,
        jsx,
        jsxs: jsx,
        jsxDEV: jsx,
      };

      window.ReactJSXRuntime = jsxRuntime;
      window['react/jsx-runtime'] = jsxRuntime;
      window['react/jsx-dev-runtime'] = jsxRuntime;
    </script>

    <!-- Load the webui library -->
    <script src="https://unpkg.com/@qwen-code/webui@0.1.0-beta.2/dist/index.umd.js"></script>

    <!-- Load the CSS -->
    <link
      rel="stylesheet"
      href="https://unpkg.com/@qwen-code/webui@0.1.0-beta.2/dist/styles.css"
    />
  </head>
  <body>
    <div id="root"></div>

    <script>
      // Access components from the global QwenCodeWebUI object
      const { ChatViewer } = QwenCodeWebUI;

      // Use the components with React.createElement (no JSX)
      const App = React.createElement(ChatViewer, {
        messages: [
          /* your messages */
        ],
      });

      ReactDOM.render(App, document.getElementById('root'));
    </script>
  </body>
</html>

For a complete working example, see examples/cdn-usage-demo.html.

Quick Start

import { Button, Input, Tooltip } from '@qwen-code/webui';
import { PlatformProvider } from '@qwen-code/webui/context';

function App() {
  return (
    <PlatformProvider value={platformContext}>
      <Button variant="primary" onClick={handleClick}>
        Click me
      </Button>
    </PlatformProvider>
  );
}

Daemon React SDK (@qwen-code/webui/daemon-react-sdk)

All daemon-related React bindings (Providers, hooks, types) are published under the daemon-react-sdk sub-path. The main entry (@qwen-code/webui) is purely UI components with zero daemon dependency.

import {
  DaemonSessionProvider,
  DaemonWorkspaceProvider,
  useTranscriptBlocks,
  useConnection,
  useActions,
  useStreamingState,
} from '@qwen-code/webui/daemon-react-sdk';

Architecture

Two providers, split by lifecycle axis:

  • DaemonSessionProvider — per-conversation: SSE connection, transcript store, prompt/cancel/model/approval-mode/permission actions.
  • DaemonWorkspaceProvider — per-workspace (outlives sessions): MCP, skills, tools, memory, agents, files.
<DaemonWorkspaceProvider>          ← owns DaemonClient + capabilities
  useMcp / useAgents / useMemory / useTools / ...
  ├── <DaemonSessionProvider>      ← owns session + SSE + transcript store
  │     useTranscriptBlocks / useActions / useConnection / useStreamingState / ...
  │     ├── <ChatPanel />
  │     └── <TerminalPanel />

Basic usage

import {
  DaemonSessionProvider,
  DaemonWorkspaceProvider,
  useTranscriptBlocks,
  useActions,
  useConnection,
} from '@qwen-code/webui/daemon-react-sdk';

function App() {
  return (
    <DaemonWorkspaceProvider baseUrl="http://127.0.0.1:4170" token={token}>
      <DaemonSessionProvider autoReconnect>
        <ChatView />
      </DaemonSessionProvider>
    </DaemonWorkspaceProvider>
  );
}

function ChatView() {
  const blocks = useTranscriptBlocks();
  const { sendPrompt, cancel } = useActions();
  const { status, sessionId, currentModel } = useConnection();
  // render blocks, handle input...
}

Dual-mode usage (chat + terminal share one session)

Wrap both views with a single <DaemonSessionProvider>. Both panels share one SSE connection and one transcript store.

<DaemonWorkspaceProvider baseUrl={baseUrl} token={token}>
  <DaemonSessionProvider autoReconnect>
    <ChatPanel />
    <TerminalPanel />
  </DaemonSessionProvider>
</DaemonWorkspaceProvider>

Do NOT nest multiple <DaemonSessionProvider> for the same session — that creates two SSE connections and potential state divergence.

Session hooks

Hook Returns
useTranscriptBlocks() readonly DaemonTranscriptBlock[] (raw blocks)
useTranscriptState() Full DaemonTranscriptState (blocks + metadata)
useActions() { sendPrompt, cancel, setModel, setApprovalMode, respondToPermission, loadSession, newSession, ... }
useConnection() { status, sessionId, currentModel, currentMode, commands, skills, models, tokenCount, tokenUsage, contextWindow }
useStreamingState() 'idle' | 'waiting' | 'responding' | 'thinking'
usePromptStatus() 'idle' | 'waiting' | 'streaming'
usePendingPermissions() Unresolved permission blocks
useActiveTodoList() Latest todo list, only when it still has active items

Workspace hooks

Require an ancestor <DaemonWorkspaceProvider>:

Hook Description
useMcp(options?) MCP server list + restart + tools
useSkills(options?) Available skills (read-only)
useTools(options?) Workspace tools + enable/disable
useMemory(options?) Memory files + read/write
useAgents(options?) Agent CRUD
useSessions(options?) Session list (switch/new/release require nested DaemonSessionProvider)
useFiles() File operations: glob, read, write, edit, stat
useGlob() globWorkspace(pattern, opts)
useWorkspace() Full workspace context value
useWorkspaceActions() All workspace-level actions

All resource hooks accept { autoLoad?: boolean, enabled?: boolean } and return { data, loading, error, reload }. When nested under an active DaemonSessionProvider, resource hooks also refresh from daemon workspace events that are already broadcast on the session stream (memory_changed, agent_changed, tool_toggled, MCP restart events, and workspace init events). Without an active session, hooks remain pull-based.

Props

DaemonSessionProviderProps:

Prop Type Default Description
baseUrl string? inherited Daemon HTTP base URL (inherited from DaemonWorkspaceProvider when nested; required in standalone mode)
token string? inherited Bearer token (inherited from DaemonWorkspaceProvider when nested)
workspaceCwd string? Override workspace path (uses capabilities if omitted)
initialSessionId string? Restore a specific session on mount
clientId string? Override stable client ID (auto-generated if omitted)
autoConnect boolean true Connect on mount
autoReconnect boolean true Auto-reconnect on disconnect
reconnectDelayMs number 1000 Initial reconnect backoff
maxReconnectDelayMs number 10000 Max reconnect backoff
suppressOwnUserEcho boolean true Suppress own user message echoes

DaemonWorkspaceProviderProps:

Prop Type Default Description
baseUrl string required Daemon HTTP base URL
token string? Bearer token
workspaceCwd string? Override workspace path
autoConnect boolean true Connect and fetch capabilities on mount

const platformContext = {
  postMessage: (message) => vscode.postMessage(message),
  onMessage: (handler) => {
    window.addEventListener('message', handler);
    return () => window.removeEventListener('message', handler);
  },
  openFile: (path) => {
    /* platform-specific */
  },
  platform: 'vscode',
};

function App() {
  return (
    <PlatformProvider value={platformContext}>
      <YourApp />
    </PlatformProvider>
  );
}

function Component() {
  const { postMessage, platform } = usePlatform();
  // Use platform capabilities
}

Tailwind Preset

Use the shared Tailwind preset for consistent styling:

// tailwind.config.js
module.exports = {
  presets: [require('@qwen-code/webui/tailwind.preset.cjs')],
  // your customizations
};
