Ever reused a UI component and spent hours guessing how it works? With Custom Elements Manifest, your components come with contracts: typed props, events, slots & CSS vars—great for docs, IDEs & storybooks. Lucien Immink shows how: javapro.io/2025/09/04/design… @openwc #WebComponents

I guess I'm officially announcing Component Odyssey: component-odyssey.com/articl… It's a course to teach developers how to build component libraries with minimal tech. CO focuses on web components, so your components will work anywhere.

Navigating Your Component Journey with Component Odyssey

There are dozens reasons to build a component library, but it's not an easy task. Component Odyssey will help you navigate your component library journey.

Interested in Web Components? Check out my latest blog. link.medium.com/jZXuvidMvyb This is a re-publication & expansion of a section from a prior post. Since then, I discovered more erroneous info I wanted to correct. I'll continue to update this new article going forward.

Look at that, @OpenWc just shipped some "spread" directives for @buildWithLit: github.com/open-wc/open-wc/b… There are A LOT of considerations to keep in mind when leveraging them: open-wc.org/docs/development… but, otherwise; glhf!

hey everyone 👋 are you using `@open-wc/[email protected]`? A proposal is out for when you don't need scoping ➡️ make it works without polyfill of scoped registry ➡️ means less js to ship ➡️ always works (no more strange errors because of loading order)
14%using it
21%using it + need scoping
14%using it + createElement

~7 more hours to go before the UKs "Mobile ecosystems market study" will stop accepting comments. There is still time to write a formless email to [email protected] Need inspirations for what to write? @brucel has you covered in his blog post brucelawson.co.uk/2022/sampl…

In case you didn't know... this might be a rough awakening 😅 Chrome, Firefox, and any browser you download on your iPhone/iPad are skins on top of the apple WebKit browser engine. The reason for this is due to section 2.5.6 in the Apple App Store rules.

If I think I'm maybe 2/3 of the way through writing a followup post to xitter.cf/OpenWc/status/14862537… on #webComponents and #a11y how much past 25% could I really be and is it possible for me to actually finish it in less than the two weeks that it has taken me to get this far? 😳
