Option 1: With JSX Support (using Babel)

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

    <script

    ></script>

    <!-- Load Babel Standalone for JSX processing -->
    <script src="https://unpkg.com/@babel/[email protected]/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/[email protected]/dist/index.umd.js"></script>

    <!-- Load the CSS -->
    <link
      rel="stylesheet"
      href="https://unpkg.com/@qwen-code/[email protected]/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= />
      );

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

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

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

    <!-- Load the webui library -->
    <script src="https://unpkg.com/@qwen-code/[email protected]/dist/index.umd.js"></script>

    <!-- Load the CSS -->

  <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>

      <Button variant="primary" onClick={handleClick}>
        Click me
      </Button>
    </PlatformProvider>
  );

Platform Context

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

tsx

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
};
