# @qwen-code/webui
A shared React component library for Qwen Code applications, providing cross-platform UI components with consistent styling and behavior.
## Features
- **Cross-platform support**: Components work seamlessly across VS Code extension, web, and other platforms
- **Platform Context**: Abstraction layer for platform-specific capabilities
- **Tailwind CSS**: Shared styling preset for consistent design
- **TypeScript**: Full type definitions for all components
- **Storybook**: Interactive component documentation and development
- **Multiple Build Formats**: Supports ESM, CJS, and UMD formats for different environments
- **CDN Usage**: Can be loaded directly in browsers via CDN
## Installation
```bash
npm install @qwen-code/webui
```
## CDN Usage
You can also use this library directly in the browser via CDN:
### Option 1: With JSX Support (using Babel)
```html
<!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)
```html
<!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>
<!-- 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>
```

## Quick Start
```tsx
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>
);
}
```
## Components
### UI Components

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

npm run storybook
```
