headlessui VS Svelte

Catalyst is a comprehensive, fully componentized UI kit for modern React projects, built on the next generation of Headless UI. With Catalyst, you can create a custom set of components to use and reuse in your projects.

And that is why I was looking for a UI library that would deliver these things for a long time and today I am happy to announce that I have found it! It is Headless UI by the Tailwind Team.

Headless UI provides a suite of unstyled, fully accessible UI components perfect for developers who want full control over their interface design. It's a developer's canvas, offering the foundational parts needed to build a user interface without dictating the aesthetics, making it ideal for those who love to integrate with Tailwind CSS. With https://headlessui.com/, you can ensure that your applications are inclusive and easy to use for everyone, while also maintaining the freedom to craft a unique look and feel that aligns with your brand or style guidelines.

Few months ago, I discovered project called Headless UI and I instantly liked the idea.

In addition to Tailwind CSS, Tailwind Labs also created Headless UI, a collection of components that work well with Tailwind CSS.

Thanks for sharing! I love projects that reimagine entire ecosystems: there's a lot of value in imagining what could be if we didn't worry about what is.

Some feedback: your comparison of the various ListBox implementations[0] feels disingenuous. I know Vue best, so I looked at that implementation in detail, and it's got a lot going on that you don't attempt to replicate in your version. A few key features that are missing:

* Search—in the HeadlessUI version there are several hundred lines dedicated to making typing work for jumping to specific list items.

* Multiselect—HeadlessUI supports multiple selections, yours does not appear to. Again, this occupies a lot of lines.

* Focus management—HeadlessUI has a lot of code dedicated to smoothing out the focus management. In my testing, your implementation has pretty buggy support for using tab to navigate.

* The HeadlessUI version dedicates a lot of lines to types, where your Nue implementation is dynamically typed. This may be a feature for you, but in my mind those type declarations are doing important work.

* In general, the HeadlessUI implementation tries to be flexible for many use cases [2], while yours only needs to support the one demo list.

You also include this render.ts file [1] from HeadlessUI, which is more part of a bespoke sub-framework used by HeadlessUI than it is a necessary part of any old Vue ListBox implementation. If you're going to count that against Vue, then there are parts of Nue JS that should be included as well.

These kinds of comparisons are most persuasive if you can write all the implementations from the ground up, using idiomatic patterns for each framework and identical feature sets for each implementation. When you do that, it's easy to compare and contrast the frameworks. As it is, it's like comparing a house to a garden shed: yes, you've used fewer lines of code, but it's not obvious to me that that's a feature of Nue and not just a byproduct of a less ambitious component.

React has introduced measures like batching state updates, background concurrent rendering and memoization to tackle this. My opinion is that the best way to solve the problem is by improving their reactivity model. The app needs to be able to track the code that should be re-run on updating a given state variable and specifically update the UI corresponding to this update. Tools like solid.js and svelte work in this manner. It also eliminates the need for a virtual DOM and diffing.

Similarly to Promises/A+, this effort focuses on aligning the JavaScript ecosystem. If this alignment is successful, then a standard could emerge, based on that experience. Several framework authors are collaborating here on a common model which could back their reactivity core. The current draft is based on design input from the authors/maintainers of Angular, Bubble, Ember, FAST, MobX, Preact, Qwik, RxJS, Solid, Starbeam, Svelte, Vue, Wiz, and more…

Svelte is a powerful web framework that offers a fresh approach to building web applications. Its simplicity, reactivity model, and built-in features make it an excellent choice for developers looking to create efficient and maintainable applications. By following this guide, you should now have a good understanding of how to get started with Svelte and build your first components, routes, and transitions. You can read more about svelte on the official Svelte website.

Use .NET features (especially dotnet watch) as a setup for a client-side Svelte application, starting from a simple C# console app.

Volar originally was Vue3's language support tool for VScode (I don't know about other editors). By today, volar has become a language indipendent framework to create language tools. It might still be a bit early for the dev with skill issues like me to use it and build some tools, but astro and svelte already use Volar to create their language tools.
