However, this only is useful if there are regular rebuilds of the site. On some days, I'm pushing new content to the site multiple times a day, each which rebuilds the site. However, I also go many days without updating which means that many webmentions are left un-rendered.
In IndieWeb Summit 2019, day 1, fluffy mentioned that they had a client-side script for rendering Webmentions. So this afternoon I thought I'd give it a go, and it was super easy and drop-in to get it working.
With this announcement, I'm now using
webmention.js to render all my webmentions on page load.
