Next-static-og-images NPM

next-static-og-images

Generate static Open Graph images for Next.js at build time

Getting started

Installation

npm i -D next-static-og-images

yarn add -D next-static-og-images

Building Open Graph images

Add next-static-og-images to your postbuild script

{
  "build": "next build",
  "postbuild": "next-sitemap && next-static-og-images"
}

The sitemap.xml is used to identify pages that need Open Graph images generated. next-static-og-images works best with a sitemap generator like next-sitemap and assumes that a sitemap.xml file is created in the public directory.

Add og:image meta tags

Add the og:image tags to your _app.js or to reference the generated images.

<meta property="og:image" content="{`${host}/open-graph${asPath == "/" ? "/index" : asPath}.png`}" />
<meta property="og:image:alt" content="..." />
<meta property="og:image:type" content="image/png" />
<meta property="og:image:width" content="1200" />
<meta property="og:image:height" content="630" />
