Haml VS Svelte

First of all, I like Slim. I like the beauty and cleanness of Slim templates, to me they are way more readable than regular ERB templates and I think they fit in the ruby/Rails ecosystem very well. Slim is a close cousin to Haml, without the ugly percent characters, haha. I've used Slim exclusively in my projects since about 2016.

If you'd rather write raw HTML, keeping track of closing tags etc, then don't use HAML. No need to bash it because you personally feel it is ugly or unnecessary. FWIW I personally feel the exact opposite.

Personally, I'd recommend Maud if you don't need something with runtime reloading. Not only is it much faster, it implements a template language that is effectively the Rust-syntax equivalent to Slim or Haml using a procedural macro, so you get compile-time verification that your HTML output is well-formed.

Does this support HAML-style syntax? We're 100% HAML-only for templating, whether normal Rails views or ViewComponent... https://github.com/haml/haml https://haml.info/ so going back to writing HTML or ERB feels like a huge downgrade.

For templating, Maud is fast, gives compile-time well-formedness guarantees, and outputs minified HTML by default as a side-effect of it being based on Rust macros. (It's of a similar design philosophy to Slim and Haml)

You don’t even need closing tags. Both Haml and Jade do away with closing tags altogether.

That looks awfully like HAML.

Your HBML is similar to HAML - is it time for HCML? https://haml.info/

it's an HTML preprocessor called HAML

Svelte and specifically, SvelteKit is an open source web framework that makes developing web applications easier.

the technical decision how Svelte should treat self-closing html elements was hindered by Prettier:

Svelte

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.
