More Fun with Invoker Commands and Web Components
July 30, 2025

So I thought it would be fun to revisit the Invoker Commands API (MDN) which is available in Chromium-based browsers and hopefully coming soon to Safari and Firefox (both are currently in testing).I’ve talked about this API before on the blog, and I continue to feel pretty excited about it since it’s the first truly declarative “click and see something happen!!” API we’ve ever seen on the web other than forms. I mean, think about it for a moment…isn’t it quite odd that there’s never been a way to write HTML (not JavaScript!) which says “when you click this button, do that thing”?!
