Someone on peerlist mentioned that he created a web app in Rust "Frontend is Leptos and backend is Axum, full stack Rust" - I've been in web development for over 2 decades now -
What's so new and shiny in this Rust framework ?
How are things different from React / NextJS etc ?
I'd say Leptos is pretty much React / Next.js for Rust. Not sure if there is anything new and shiny about it; the first release is over 4 years old. This is a mature project. There is a chapter about deployment of client-side and hybrid apps in the book if you are interested. I'd say it's pretty much as difficult as deploying a Node server, sans the services that specialise in that (I don't think there is a service that is focused specifically on hosting hybrid Leptos apps).
The most notable difference is no virtual dom but I guess that is not your main concern. If you want Next.js in rust then yes, Leptos is one of the similar products and Dioxus is the one with the virtual doms approach.
I create web applications using Rust, however my stack doesn't include any of your components. The world is a really big and you can always find not occupied niche for your talents.
More like SolidJS, because of how reactivity and DOM updates work. The only real difference Is that using Rust sometimes creates a lot of friction: some pattern that simply work in JavaScript don't make the borrow checker too happy. Server-side functions (you write them in the client and get translated to server code + client HMR call) are great. Deploy is OK anywhere you can run an executable. In the end it works quite well even if it is still a bit rough aeound the edges.
BTW, I use Rust with Polars in some data heavy web apps and It works great: much more responsive than processing the data on the server.
