Effortlessly run Python code in your React apps.

Try it out

You can try out react-py in the playground.

Quickstart

Install react-py with:

npm install react-py

Then, wrap your app in a PythonProvider component.

import { PythonProvider } from 'react-py'

function App() {
  return (
    // Add the provider to your app
    <PythonProvider>
      <Codeblock />
    </PythonProvider>
  )
}

render(<App />, document.getElementById('root'))

Using the usePython hook, you can run code and access both stdout and stderr. For full usage instructions and framework specific guides, see the usage docs.

• multiprocessing
• threading
• sockets
