Web Components! This post by @zachleat.com is a good example of a case where it can make fine sense to use an empty custom element that doesn't need to wrap already-functional/meaningful HTML. Those cases tend to be the exception in my experience/preference though!

I am looking for a full-time job.
Being independent in open source for 3.5+ years has been wonderful. I've gotten done most of the high-level goals I wanted to, and miss having people & structure around me.
If you know of a role for a staff-level TypeScript+web developer, let me know! 🙂

Seconded! A great course and a bargain to boot.
I got access shortly after Scott's course launched and it is hands down the best course on web components I have seen. Beginner-friendly yet covers all the ground you need to get started with web components.
Can't recommend it enough.

Sometimes you only want a field to show when certain other fields have a (particular) value. The `form-show-if` web component enables that.
A Web Component for Conditionally Displaying Fields :: Aaron Gustafson
Building on my recent work in the form utility space, I’ve created a new web component that allows you to conditionally display form fields based on the values of other fields: form-show-if.

This is the most personal project I’ve made in years.
I launched a new show called The Callback. It’s weekly web dev news with my dumb humor sprinkled on top.
If this pilot does well I get to make more, so watching, liking, and sharing would be DEEPLY appreciated 💜
