react

React is a JavaScript library for creating user interfaces.

This fork is published as react-treeshake. It preserves the CommonJS entry points from React 19.2.7 and adds native .mjs development and production builds for React, the JSX runtimes, and the compiler runtime.

Use it as a drop-in replacement with pnpm's package alias support:

{
  "dependencies": {
    "react": "npm:[email protected]"
  }
}

Or install the alias from the command line:

pnpm add react@npm:[email protected]

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 />);
