You can use the following code sample to explore using parameters and different content types with next/og. To learn more about OG Image Generation, see Open Graph Image Generation.

Create an api route with route.tsx in /app/api/og/ and paste the following code:

Next.js (/app)
Next.js (/pages)
Other frameworks
app/api/og/route.tsx
import { ImageResponse } from 'next/og';
// App router includes @vercel/og.
// No need to install it.
 
export async function GET() {
  return new ImageResponse(
    (
      <div
        style={{
          fontSize: 100,
          color: 'black',
          background: 'white',
          width: '100%',
          height: '100%',
          padding: '50px 200px',
          textAlign: 'center',
          justifyContent: 'center',
          alignItems: 'center',
        }}
      >
        👋, 🌎
      </div>
    ),
    {
      width: 1200,
      height: 630,
      // Supported options: 'twemoji', 'blobmoji', 'noto', 'openmoji', 'fluent' and 'fluentFlat'
      // Default to 'twemoji'
      emoji: 'twemoji',
    },
  );
}

If you're not using a framework, you must either add "type": "module" to your package.json or change your JavaScript Functions' file extensions from .js to .mjs

Preview the OG route locally by running the following command:

pnpm
yarn
npm
pnpm dev

Then, browse to http://localhost:3000/api/og. You will see the following image:
