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

    />
  </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"

    ></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...
}

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.

Platform Context

The Platform Context provides an abstraction layer for platform-specific capabilities:

import { PlatformProvider, usePlatform } from '@qwen-code/webui/context';

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
};
