declarative-shadow-dom VS shoelace-css

Take a look at Declarative Shadow DOM: https://github.com/mfreed7/declarative-shadow-dom

Hmm, I see that Chromium shipped their implementation a year ago now; I had missed that. Other than that, there’s been no real change in the situation in the last almost two years (since Shoelace 2.0 was released, the last time I examined the situation). And there still doesn’t look to be any real interest in actually implementing it outside of Google: Mozilla are unenthusiastic though not against it <https://mozilla.github.io/standards-positions/#declarative-s...>, and WebKit still find fault with some aspects of the design (https://lists.webkit.org/pipermail/webkit-dev/2021-February/..., https://github.com/mfreed7/declarative-shadow-dom/issues/9), though they’re content most of the earlier issues are ironed out.

So you certainly can’t rely on scriptless server-side rendering of Shadow DOM being possible—it’ll work in Chromium only, and it’ll probably be at least another year or two before other browsers even contemplate doing anything with it.

(And of course, even once Shadow DOM is serialisable, that’s a far shot from a particular frameworky thing being SSR-compatible, but I was quibbling over the Shadow DOM and impossibility aspects, so I shan’t step back on that.)

HTMX gets all the hype right now, but there are other tools in the same vain, my favorite being Unpoly (https://unpoly.com). Together with Shoelace (https://shoelace.style) you get nice GUIs real fast, without the burden of complicated dependency management and build steps. Also, you don't have to write a lot of JS, just what is needed for small enhancements, as it was meant to be. Some might say the main drawback is the tight coupling to your backend. In my case, this is also the main benefit as it integrates perfectly with the backend framework (Django).

Hello HN,

I'm releasing Hyperdiv (https://hyperdiv.io), a framework for rapidly developing reactive browser UIs in Python, with immediate-mode syntax and using Shoelace (https://shoelace.style) as its built-in component system.

This short coding video will give you a good idea of what it is: https://www.youtube.com/watch?v=4XJKfxaqvGE

I wrote a brief article about the motivation and approach: https://hyperdiv.io/intro.html

Hyperdiv doesn't aim to compete with serious full-stack frameworks. The core aim was to make it easy and fast to prototype apps and build UI-based tools. I was originally motivated by internal tools at work -- feeling the need to quickly put together UI-based tools to share with both technical and non-technical coworkers, without having to stand up and maintain a full internal stack.

This is my first major open source release. I really appreciate your feedback and support. - Marius

For example, all the following design systems can be used without tooling (some of them provide ready-to-use bundles, others can be used through import maps): Google's Material Web, Microsoft's Fluent UI, IBM's Carbon, Adobe's Spectrum, Nordhealth's Nord, Shoelace, etc.

Here's what this looks like - note that I'm using Shoelace components for styling purposes.

There are lots of open-source design systems built with Lit. Shoelace is a popular component set that you might check out: https://github.com/shoelace-style/shoelace There are many others...

Would it help if we listed more open source projects on our site?

Because of our focus on components and the fact that you really can use just about any libraries and scaffolding for apps, we don't really have an app starter kit, but it's something we've talked about.

I'm really excited about all this, and it makes me have some faith in the web again. I think that Lit is a step in the right direction especially the ability to do SSR / SSG and hydrate a web page. Hopefully 🤞 Shoelace can get SSR running, which is currently one hurdle, but I think it is achievable.
