Automatically parses your posts and generates social cards for Twitter, Slack, Facebook and other sites.

To learn more about social-cards in general, check out open graph, twitter cards and this CSS tricks article on meta-tags for social.

Current Status: Beta

I’m using this for and it works for me, both locally and for Netlify builds. Contact me on Twitter if you’re testing this and it fails.

Only works for remark nodes at the moment.



There are two design available now, “card” and “default”. But we can expand that later.

default card design

default card design

default card design

Custom Backgrounds

You can put a cover frontmatter on your post, and we’ll use that. Otherwise, we’ll use a default-background that you can specify or if that fails, we’ll use a fallback one.

Custom Author image

If specified, an author image is shown on the image. That is also configurable.

Powerd by SVG, React and Sharp

We use the same underlying library that powers gatsby-images to convert our React generated SVG files into images.


yarn add @andrioid/gatsby-plugin-social-card
# or npm install --save @andrioid/gatsby-plugin-social-card

How to use

Configure our site to use the plugin by editing gatsby-config.js. You don’t need to specify options.

plugins: [

If you want to customise the look of the cards, try these options.

plugins: [
		resolve: '@andrioid/gatsby-plugin-social-card',
		options: {
			// ommit to skip
			authorImage: './static/img/coffee-art.jpg',
			// image to use when no cover in frontmatter
			backgroundImage: './static/img/hvitserkur.JPG',
			// author to use when no auth in frontmatter
			defaultAuthor: 'Andri Óskarsson',
			// card design
			design: 'default' // 'default' or 'card'

Then you need to add the meta tags to your site. For a more complete example of meta tags, check out seo.js from Kent C. Dodds.

import Helmet from 'react-helmet'

const image = node.frontmatter.socialcard

export const SEO = ({ postData, frontmatter = {}, metaImage, isBlogPost }) => (
		{/* Your other meta tags... */}
		<meta name="image" content={image} />
		<meta property="og:image" content={image} />
		<meta name="twitter:card" content="summary_large_image">
		<meta name="twitter:image" content={image} />



We use sharp to convert our SVG images to JPG. The means that the fonts available to you are limited to those of the build-machine.

VIPS image library

Depending on your installation, SVG support in libvips (used by Sharp) might be missing.

It needs to be built with JPEG and SVG support.
