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

Does anyone know someone from npm/github/microsoft? We really would like to get a hold on the unused `owc` npm namespace - but we are not getting any replay since February 😅 We opened "npm Name Disputes submission #2569951" any ideas/hints?

Version 2.1.1 of `@open-wc/scoped-elements` is out 🎉 With it, we no longer automatically load a polyfill for a scoped registry. Which results in ⬇️ smaller size 👼 fewer errors when integrating components in pages As long as you are not requiring scoping no change is needed

If you need scoping and you are already using `@open-wc/scoped-elements` then loading the polyfill for the scoped registry will enable it. And if you are imperatively creating elements then you should use the `createScopedElement` method.
