In a recent post I covered how to get MDX-style posts with web components and people come to me every day, tears in their eyes, and ask me to go into more detail.
Seriously, tho it’s just regular markdown…
blah blah blah
<script type="module" src="path/to/my-cool-component.js"></script>
<my-cool-component></my-cool-component>
blah blah blah
And it’ll pretty much work.
