Generating OG Images - Supabase

Generate Open Graph images with Deno and Supabase Edge Functions. View on GitHub.

Code

Create a handler.tsx file to construct the OG image in React:

tsx

import React from 'https://esm.sh/[email protected]'
import { ImageResponse } from 'https://deno.land/x/[email protected]/mod.ts'

export default function handler(req: Request) {
  return new ImageResponse(
    <div
      style={{
        width: '100%',
        height: '100%',
        display: 'flex',
        alignItems: 'center',
        justifyContent: 'center',
        fontSize: 128,
        background: 'lavender',
      }}
    >
      Hello OG Image!
    </div>
  )
}

Create an index.ts file to execute the handler on incoming requests:

import handler from './handler.tsx'

console.log('Hello from og-image Function!')

Deno.serve(handler)
