I hate saying things which seem blindingly obvious, but when Famous People™ such as Theo on YouTube make these basic mistakes, I wonder. 
So here you go:
`document.querySelector("# my-dumb-button").addEventListener(...)` is completely obsolete in the year 2025.
Never do that again please. You don't need to!
If you're wondering “well, what should I do instead?”, check the comments; we'll talk about what to do instead. Apparently it will BLOW YOUR MIND! 
What impressed me was the prioritizing of economic justice at the framework level. That manifests in minimal code sent to the client hosted on a Cloudflare edge worker for free; reducing costs for website owners and customers.
No $20/mo hosting lock-in scheme.
Wish #webcomponents had an SDK like this...
A great behind the scenes look at all the effort that goes into building an accessible Shopify theme by @NicMakesStuff
There's also a nice bit in there about how #WebComponents are a great fit for a one-time purchase theme that you support forever because "their extensibility is unmatched" and "they never need to be updated".

I love that I can add CSS custom properties to a Custom Element Manifest via JSDoc. Let's see if I can add the idents/keys as specific properties to a JSX style attribute object. #css #jsdoc #cem #webcomponents
Today I saw someone coming up with their own #html tags. At first I thought they were #WebComponents but the naming was off:
<holiday>, <employee>, <month> and many more
Looked at it in the #accessibility tree, they're all generic elements.
What really amazes me is the browser still rendering the content inside and simply not giving a fuck if it's fantasy HTML 
(I would be shocked if someone shows me a link to the specs for these elements in the comments )
ap-components
I want to share some information about a repository we just published. ap-components is a set of Web Components for building interfaces for the ActivityPub API. I built it as I was making a sample application for handling the acct: URI scheme. I found myself making more and more components for the UI, and realised that they would probably be useful for other applications, too. The library is available on npm at @socialwebfoundation/ap-components. It currently covers some of the simplest […]
#WebComponents people, in this Codepen that I set up for testing, the dialog inside the #ShadowDOM cannot be open by its sibling button even enough they're connected by correct ID attribute.
Is this expected or am I missing something here?
shopify embracing web components. lightdom web components no less.

Introducing Syncfusion’s Pure React Components: Built from the Ground Up for React.
I really like web components! They make developing frontends so much easier..
Does anyone have good reading on how major frameworks make their SPA url router? I'm not talking about a hash router, I'd like to see how (with the server configured properly) the JS handles all the things (history pop state changes, link clicks, etc)
Nice write-up about django-bird and dj-angles in https://bencardy.co.uk/2025/03/24/birds-and-angles-dabbling-in-django-components/
shadow parts are pretty good actually.
https://plainvanillaweb.com is a cool, simple site that shows and tells you how to de-framework. Useful info today in a world or gunked-up, cluttered, crappy and overly complicated websites.
@jensimmons Thanks for the question! Once again I'm asking for the support to extending built-in elements for #webcomponents
I've recently found that many confuse attributes and properties in web components and javascript. Here's a quick explainer with some opinions and life advice:
