hotwire-rails VS Svelte

Applications generated with Rails 7 will get Turbo and Stimulus (from Hotwire) by default, instead of Turbolinks and UJS. Hotwire is a new approach that delivers fast updates to the DOM by sending HTML over the wire.

For Ajax-y stuff, I am really excited by the new crop of "HTML-as-a-Service" or "HTML-over-the-wire."

For all the turbo/stimulus/hotwire mix, you want to add a new feature just for the sake of adding it? or do you have a use case that fits the feature? if you have then you probably already have an implementation with a different technology (stimulus reflex? some custom websockets or ajax implementation? something with anycable?) and you have to check how to migrate from that technology to hotwire. If you just want to use the feature with no real need for it to practice then just pick any tutorial from the internet (like the intro in the official website https://hotwired.dev).

I was recently interested in similar topic. Here are 3 similar solutions I found:

* https://unpoly.com/

* https://hotwired.dev/

My personal preference is Unpoly (the idea of "layers" is awesome). But the best explanation of concept as a whole (HATEOAS, keeping app state on server using partial page updates, etc) is at HTMX homepage, and in these essays:

At the end of 2020 the Basecamp team released a collection of Javascript libraries called Hotwire. Modern web stacks have popularized javascript-rendered front ends and JSON transmissions. Hotwire's primary motivation is to reduce the Javascript footprint and allow application front ends to be created in primarily HTML. It pairs very nicely with the Ruby on Rails ideology and is often demonstrated in that context. I aim to write a series on how Hotwire can be used in any application to simplify development and reduce the need for heavy Javascript downloads. Hotwire currently consists of two javascript libraries: Turbo and Stimulus. The first part of this series introduces Turbo.

I've been doing that a while until I just got sock of the JS spagetti and often duplicated code and went full on Angular CSR and never looked back. That being said, I've been seeing a lot recently about Laravel's Livewire and Symfony and Ruby on Rail's integration with Hotwire (stimulus+turbo).

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.
