A full-featured web components library based on Vue3

• Based on custom elements and shadow DOM, works with all frameworks
• Well-encapsulated features and few required dependencies(vue and floating-ui), provides a set of high-quality components, relatively lightweight
• Provides abundant global static and dynamic configurations, easy to customize not only CSS but also many internal behaviors
• Styleless or with a beautiful preset theme based on @radix/colors, out-of-box dark mode and responsive ui support
• Ready to use new Web APIs (Popover API, CSS Anchor Positioning CustomStateSet...), provide reasonable fallbacks
• Full typescript support, provide type definitions for all components

Warning

Not production ready, still in development, you can keep an eye on it. Feel feel to give me any kind of feedback, also contribution is welcome.

FAQ & Roadmap

Why Vue3

I'm convinced by Vue3 defineCustomElement, a proper runtime is necessary for better DX. Also, most cross framework libraries use class oriented way to build themselves, I prefer hook and composition way so I chose Vue3's defineCustomElement. It's good trade-off if you use amounts of components

Why another library?

There are plenty of powerful web libraries, why creating new one?

Well, mainly for personal learning and summary. I'm interested in cross-framework library as we could have great and unified DX in different frameworks with it. Shadow DOM is an option, but obviously it's not that convenient. It's complicate on customizing CSS, hard to manage its children nodes, no dynamic slots and so on.

I don't found any library based on shadow DOM that has both useful and out-of-box features and easy customization, maybe it's because of the limitation of shadow DOM. So I decided to think up some ways to make it work.

Could it be used in Vue2?

Technically yes, because web components is not framework-specific, but you need to handle the import from vue2 and vue3 properly. Definitely needs some configurations in different CLI, haven't tested yet.
