Open Graph photographs. These little photographs that present up when your web site is shared on social media. Those for my web site had been… unhealthy. My default was to make use of one, big, boring branded picture for all the pieces—which supplied no additional worth and simply cluttered up y’alls feeds (sorry!). I needed to make them higher and right here’s what I did.

The Lazy Methodology

Whereas constructing a screenshot cloud service for 11ty.dev, it grew to become apparent that I ought to add an Open Graph measurement to make use of screenshots as Open Graph photographs. You possibly can see this in use on the Eleventy docs pages:

  • Navigate to https://www.11ty.dev/docs/
  • With the screenshot service in place, it’s only one line for a customized Open Graph picture: <meta property="og:picture" content material="https://v1.screenshot.11ty.dev/https%3A%2F%2Fwww.11ty.dev%2Fdocs%2F/opengraph/">
  • The social card picture appears to be like like this: Open Graph images for 11ty.dev/docs/

For the quantity of labor this took to setup, it was completely price it (one <meta>!). However I needed to take it to the following stage for my private weblog (with a long run purpose of possibly convincing my colleagues to make use of one thing like this on netlify.com 😅).

The Underwhelming Methodology

Prior to now, I did experiment a bit with utilizing the SVG to raster picture function of Eleventy Picture (by way of sharp) but it surely wasn’t fairly what I needed. It had the good thing about being a lot quicker than HTML-based strategies (often primarily based on Puppeteer) however I ended up having to slog by way of a bunch of hand-written SVG to get it to look how I needed to look. I’ll admit, I’m not as productive at hand-authoring SVG as I’d like.

The Fancy Methodology

With these experiences beneath my belt, I made a decision to customized design a web page on my web site (supply code) that will iterate over every weblog put up and will function the goal for my screenshot service. This supplied a few advantages:

  • I can use the entire present HTML/CSS/JS/Fonts already in use on my web site. Meaning faux browser chrome, customized Twitter avatars, Lighthouse scores, recognition ranks, amongst others!
  • I don’t must run Puppeteer regionally. I attempt to keep away from this when doable—it’s superior but it surely slows down the construct (lots).

Every particular person weblog put up has a devoted Open Graph picture web page, for instance /opengraph/net/automatic-opengraph/ (Truthful warning: this web page isn’t utilizing responsive net design ideas. It’s particularly created for the 1200×630 side ratio).

If I need a customized background picture for a single put up’s open graph picture, I add entrance matter with the picture url:

---
search engine marketing:
openGraphBackgroundImage: /og/sources/graphpaper.jpg
---

Subsequent, in my base Eleventy format file (supply code) I level the Open Graph web page for every particular weblog put up in direction of the screenshot service to seize the picture:

https://v1.screenshot.11ty.dev/https%3A%2F%2Fwww.zachleat.com%2Fopengraph%2Fweb%2Fautomatic-opengraph%2F/opengraph/_20210830_b/

It appears to be like like this:

I needed the picture to have the put up title, my avatar, the printed date, and the URL of the web page.

For bonus metadata, right here’s one with a Lighthouse rating hooked up (up to date recurrently by way of Speedlify), a webmentions rely, and even the web page weight (e.g. 226 KiB, additionally pushed by Speedlify):

DevTools Machine Emulation

Within Chrome Devtools, I added a customized Emulated Machine particularly for Open Graph picture codecs to check the layouts.

Social Card Preview

I added a bit <particulars> on the underside of every weblog put up in order that I might check the social card picture preview. I’ll most likely pivot this to a link-based sharing widget sooner or later or mix into my present Retweet to Share part.

On-demand Builder Cache Busting

The Eleventy Screenshot service is an unbiased undertaking that makes use of On-demand Builders to cache screenshot picture content material to Netlify’s CDN. That cache is fairly sticky. The best strategy to invalidate the cache is to set off a Screenshot service construct on Netlify, however that will reset the cache for all screenshots saved by the service, which is simply too heavy. It has been a standard request for a extra granular Netlify API to reset items of the cache however throughout the improvement of this undertaking I spotted that we will deal with this manually on the app facet utilizing our previous good friend, the Cache Buster URL.

If the previous URL regarded like this https://v1.screenshot.11ty.dev/https%3A%2F%2Fwww.zachleat.com%2Fopengraph%2Fweb%2Fcomprehensive-webfonts%2F/opengraph/, I can add an arbitrary cache busting key to the tip of it (prefixed by an underscore to determine it anyplace within the URL).

If I generated that key with in the present day’s date (e.g. https://v1.screenshot.11ty.dev/https%3A%2F%2Fwww.zachleat.com%2Fopengraph%2Fweb%2Fcomprehensive-webfonts%2F/opengraph/_20210803/), it might generate new photographs day by day with out the screenshot service needing to invalidate the complete cache.
