Code

Find the code at github.com/lpolish/next-auto-og-image

Features

Automatically generates OG images for all pages in your Next.js project
Uses actual page screenshots for accurate representation
Integrates seamlessly with Next.js App Router
Updates OG images during the build process

Installation

Install the package using npm:

npm install next-auto-og-image

Usage

Update your next.config.js file to include the plugin:

const withAutoOGImage = require('next-auto-og-image/next-plugin')

/** @type {import('next').NextConfig} */
const nextConfig = {
  // Your existing Next.js config
}

module.exports = withAutoOGImage(nextConfig)

In your app/layout.tsx file, use the getOGImageMetadata function:

import { Metadata } from 'next'
import { getOGImageMetadata } from 'next-auto-og-image'

export async function generateMetadata(): Promise<Metadata> {
  const ogImageMetadata = await getOGImageMetadata('app/layout.tsx')
  
  return {
    ...ogImageMetadata,
    // Add any other metadata here
  }
}

export default function RootLayout({
  children,
}: {
  children: React.ReactNode
}) {
  return (
    <html lang="en">
      <body>{children}</body>
    </html>
  )
}

For individual pages, add the following to each page.tsx file:

import { Metadata } from 'next'
import { getOGImageMetadata } from 'next-auto-og-image'

export async function generateMetadata(): Promise<Metadata> {
  const ogImageMetadata = await getOGImageMetadata('app/example/page.tsx')
  
  return {
    ...ogImageMetadata,
    // Add any other metadata here, or override the OG image if needed
    // openGraph: {
    //   images: [{ url: '/custom-image.png', width: 1200, height: 630 }],
    // },
  }
}

export default function ExamplePage() {
  return <h1>Example Page</h1>
}

How it works

During the build process, the plugin starts a development server.
It then scans your app directory for all page files.
For each page, it generates a screenshot using Puppeteer.
The screenshots are saved in the public/og-images directory.
The getOGImageMetadata function provides the correct metadata for each page.

Configuration

Currently, the package uses default settings for OG image generation. Future versions may include customization options.

Requirements

Next.js 13.0.0 or higher
Node.js 14.0.0 or higher

Limitations

The development server needs to be able to render your pages correctly for accurate screenshots.
Pages with dynamic content may not be represented accurately in the OG images.
