- Replace __dirname with import.meta.url pattern for ES modules compatibility - Add fileURLToPath imports to all E2E test files - Fix duplicate require statements in setup-verification.spec.ts - Update playwright.config.ts to use relative path instead of __dirname This fixes the 'ReferenceError: __dirname is not defined in ES module scope' error when running Playwright tests in the ES modules environment.
react
React is a JavaScript library for creating user interfaces.
The react package contains only the functionality necessary to define React components. It is typically used together with a React renderer like react-dom for the web, or react-native for the native environments.
Note: by default, React will be in development mode. The development version includes extra warnings about common mistakes, whereas the production version includes extra performance optimizations and strips all error messages. Don't forget to use the production build when deploying your application.
Usage
import { useState } from 'react';
import { createRoot } from 'react-dom/client';
function Counter() {
const [count, setCount] = useState(0);
return (
<>
<h1>{count}</h1>
<button onClick={() => setCount(count + 1)}>
Increment
</button>
</>
);
}
const root = createRoot(document.getElementById('root'));
root.render(<Counter />);
