"scripts": {
    "start": "snowpack dev",
    "build": "snowpack build"
}

React

Now lets add react:

1
  npm install react react-dom --save

And create our files:

src/index.tsx:

  import React from "react";
  import ReactDOM from "react-dom";
  import App from "./App";

  ReactDOM.render(<App />, document.getElementById("root"));

  import React, {useState, useEffect} from 'react';

  function App() {
    // Create the count state.
    const [count, setCount] = useState(0);
    // Update the count (+1 every second).
    useEffect(() => {
      const timer = setTimeout(() => setCount(count + 1), 1000);
      return () => clearTimeout(timer);
    }, [count, setCount]);
    // Return the App component.
    return (
      <div className="max-w-screen-lg mx-auto pt-4">
        <header>
          <p>
            Page has been open for <code>{count}</code> seconds.
          </p>
        </header>
      </div>
    );
  }

  export default App;

  // postcss.config.js

      // other plugins can go here, such as autoprefixer
    },
  };

  // tailwind.config.js
  module.exports = {
    mode: 'jit',

      },
      devOptions: {
          tailwindConfig: './tailwind.config.js',
      },
      plugins: [
          '@snowpack/plugin-postcss',
      ],
  };

Then create the css:

@tailwind base;
@tailwind components;
@tailwind utilities;
