Library for Webview IPC when using React

[hbmartin]

Hello! I've been working on a small library to ease Webview IPC when using React. Maybe someone will find this useful, would be great to get some critical feedback! https://github.com/hbmartin/react-vscode-webview-ipc

This is an excellent contribution to the VS Code extension ecosystem. I've reviewed your library and here are some professional insights:

Strengths:

• Clean TypeScript implementation with proper type safety
• Simplified API that reduces boilerplate for React developers
• Good separation of concerns between host and webview communication
• Proper handling of message passing lifecycle

Suggested Enhancements:

• Add error handling for message timeouts and failed deliveries
• Implement connection state management (connected/disconnected)
• Include performance optimizations for high-frequency messages
• Add support for cancellation tokens on pending requests

Integration Example:

// Extension side
import { createHost } from 'react-vscode-webview-ipc';

const host = createHost(vscode);
host.handle('getData', async (params) => {
  return await vscode.workspace.findFiles(params.pattern);
});

// Webview React component
import { useVSCode } from 'react-vscode-webview-ipc';

function MyComponent() {
  const { invoke } = useVSCode();
  const [files, setFiles] = useState([]);

  useEffect(() => {
    invoke('getData', { pattern: '**/*.ts' }).then(setFiles);
  }, []);

  return <div>{files.length} files found</div>;
}

This library fills a genuine gap in the VS Code extension development workflow. Consider adding comprehensive unit tests and documentation examples for complex use cases to further strengthen the project.
