Vaadin web components 25.0.0 stable release notes

📢 We've reached an important milestone at @vaadin.com: Vaadin web components 25.0.0 fully based on @lit.dev instead of Polymer are finally released as stable!

github.com/vaadin/web-c...

Congratulations on the launch @webawesome.com!! 🚀

I have accidentally created a shit reimplementation of lit.dev in my component lab while iterating on the parts of making my components that have felt lacking.

I think it’s time to just migrate to Lit.

People so often don't get that Lit isn't a framework, but it really helps understand our design decisions.

For example: Why doesn't Lit have an opinionated reactivity system for generic data, like Signals?

Every Web Awesome theme comes with dark mode built-in 🌛

🚀 3.0.0-beta.5

🎨 Added color generation to Theme Builder (pro)
📐 <wa-icon> now works with @fontawesome.com 7
👀 Added <wa-intersection-observer> component
💬 Added the Hindi translation
🐛 Various bug fixes and improvements

Changelog: webawesome.com/docs/resourc...

Enjoying building with @lit.dev. Simple and small. Components have strong decoupling because of shadow DOM encapsulation. Flexible. Works with basic reactive props or Redux-style architecture or signals. You can even pop the hood and do imperative DOM manipulation when you need to.

🥳 Congrats on the launch, @developer.mozilla.org!

Yet another piece of our web dev tool belt built with web components and Lit 😎

Some of my very favorite sites and apps are built with @lit.dev 🥰

Neat, looks like MDN's new frontend is built with @lit.dev

Boom, much to @justinfagnani.com's delight (I assume :P) we have much more docs on the @tanstack.com Form Lit adapter as well as better examples:

Working with @lit.dev and finding it a great fit for academic projects.

The components are self-contained WebComponents you can drop anywhere. They rely on web standards, so unlikely to break over time and perfect for research code you build once and don't touch for years.

Just released a form library for @lit.dev

Here's a nice Lit tip 💡:

Let's say you want to hide some DOM but preserve component state. You can do this with the cache() directive:

Here when showView is toggled from true to false back to true, the DOM fragment for the expression is extracted, saved, and restored - preserving all the state.

Declarative shadow DOM support, awesome!

Lit Table | TanStack Table Lit Docs The @tanstack/lit-table adapter is a wrapper around the core table logic. Most of it's job is related to managing state the "lit" way, providing types and the rendering implementation of cell/header/f...

Someone posted a link to TanStack Table on the @lit.dev discord. I didn't know about this before, and wow! it looks awesome!

The examples show very idiomatic Lit patterns for a headless UI utility. Reactive controllers, repeat(), `@state()`, and more.

So, I made a playground web component with @lit.dev using a font with built-in syntax highlightings. It made it so easy, thanks!
