inertia-rails VS Svelte

I'm assuming your friend's comment about React/Laravel is referring to Inertia.js, which is a commonly used library in the Laravel community. If thats the case, Inertia is also available for Rails: https://github.com/inertiajs/inertia-rails

I'd like to recommend Inertia.js. it essentially adds JavaScript frameworks as a view layer and seamlessly hands data off from your controllers to your react components. You don't need to maintain an API or set up GraphQL. It can be added to your project alongside your existing views. I've been using it for a few projects and I love it.

Svelte is handled as a competetitor of react. It es easier to learn, no virtual dom. Together with inertia-rails its well connected to the backend and you can use the rails-router. JavaScript and html are together in a .svelte file.

Here's an example app using [Vue.js in Rails](: https://github.com/ElMassimo/pingcrm-vite), which uses Inertia.js to provide a SPA-like experience. What's nice about it is that you could try it in a single page/endpoint, and will still integrate nicely with the rest of your application.

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.

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