Using Components in Astro

Astro allows you to use components from your favorite frameworks. Here's an example using a React component.

  return <button className="btn">{children}</button>
}
 
export default Button

Use the Component in Astro

Import and use your React component in an Astro page:

<!-- src/pages/index.astro -->
--- import Button from '../components/Button.jsx'; ---
 
<!doctype html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Welcome to Astro</title>
  </head>
