sycamore VS rust-dominator

Perseus is a fast frontend web development framework for Rust with built-in support for reactivity using Sycamore, server-side rendering, and much more. Sycamore is a frontend library that allows you to build interactive user interfaces with Rust. I’d say that Perseus is to Sycamore as Next.js is to React, so it’ll be helpful for you to have a fair understanding of Sycamore before jumping into using Perseus — although it’s not necessary to follow along in this article.

Now, I considered whether to spend more time fixing everything that now failed in sycamore 0.9. But there are major changes ahead which would require yet another major refactoring, to the point where I am not sure whether it would not be more of a rewrite than a refactoring, given my previous experiences with sycamore.

Sycamore.

Sycamore, Yew, or Seed if you want a full-stack solution. (Or Leptos if you want something that's faster but less mature.)

There are others, like Sycamore, similar story as Leptos but imo Leptos is (currently) more ergonomic.

Sycamore is a reactive library for creating web apps in Rust and WebAssembly. https://github.com/sycamore-rs/sycamore

I tried my first project with yew as frontend. And my experience was after some time similar to the already mentioned ones: It is a little more to take on than I actually wanted. And some things were not straightforward to achieve. I switched to sycamore for the other projects now and I am much more satisfied (but this could also be since I have some more experience in the Rust ecosystem by now). Changing from yew to sycamore was pretty easy and I can achieve most of the tasks with less code.

If you want to do fullstack/SPA stuff, check out Sycamore, Seed, and Yew.

If you want to do front-end SPA development, take a look at Yew, Seed, or Sycamore.

I have written a front-end (website) application in Rust that is used internally in production. I wouldn't recommend to use something like sycamore, leptos, dioxus, yew for you next puplic web-app now but i can absolutely see how this is used in the future as those libs mature.

They are both async and made for GUI -- in case of rust-signals WebGUI, provided by dominator and MoonZoon.

You shouldn’t ever need to deal with OsString itself on wasm32-unknown-unknown, since that target basically just doesn’t cover functionality that needs it, but the actual situation is genuinely worse than OsString: Rust insists on valid Unicode (as is right and proper), but the web suffers from the affliction of ill-formed UTF-16. If you blindly convert from JavaScript strings to Rust strings, you will encounter data and functionality loss in a few situations, in practice always involving IME (or similar) text entry on Windows. The first bug I filed about this: https://github.com/Pauan/rust-dominator/issues/10, and you can follow further links if you’re interested. IE and Edge used to be largely immune to this, but IE is dead and I suppose Edge will have regressed in this way with the Chromium migration, since the bug filed in Chromium a few years ago <https://bugs.chromium.org/p/chromium/issues/detail?id=949056> has languished. (Firefox too, with <https://bugzilla.mozilla.org/show_bug.cgi?id=1541349>.) In the worst-case scenario, careless use like was the case in rust-dominator will mean that some users typing with particular software in a language that’s outside the Basic Multilingual Plane will not be able to type anything.

One comparison I'm missing , which I think provides quite a nice solution in Rust, is the signals based approach popularized by Solid JS and implemented in Rust by sycamore and earlier by dominator.

Missing support for characters beyond U+FFFF is the main problem caused by surrogates (their existence, even if indirect)—it normally comes of some kind of UCS-2/UTF-16 confusion. It’s not fair to disqualify them. The only (class of) case that I’m aware of for a long time where it’s not linked to that is with MySQL’s idiotic utf8 → utf8mb3 type.

You may not have encountered such bugs, but I’m very familiar with surrogate-related bugs, because I use a Compose key extensively. I haven’t been using Windows for the last year, but from time to time I would definitely encounter bugs that are certainly due to surrogates. On the web, I found bugs a few times, all but once in Rust WebAssembly things, such as https://github.com/Pauan/rust-dominator/issues/10. And even now I’m back on Linux, I know of one almost certainly surrogate-related bug: I can’t type astral plane characters in Zoom at all; pretty sure I had this problem back on Windows, too. Copy and paste, sure, but type, no, they become REPLACEMENT CHARACTER.

The history is unfortunate but I strongly refute that they had not much choice. UCS-2 should have been abandoned as a failed experiment. Certainly there had been significant investment into it in the last few years, but with the benefit of hindsight, switching to UTF-8 (which was invented before they decided on surrogates) would have made everyone’s life much easier, especially given its ASCII-compatibility.

Ah, BOM characters. Haven’t seen one in years. Good riddance.

I really don't understand why everyone jumps to Yew when it comes to front-end development. Dominator is a far cleaner and more Rust-orientated approach to building front-end apps. I have worked with both and I feel that Yew adds a lot complexity/forces a lot of design philosophies but gives very little back in terms of advantages.

Hi, I've just released a major new version of Silkenweb. It's a signals based web framework like Dominator or Sycamore, but with the emphasis on plain rust syntax rather than a macro DSL.

Check out the alternatives without vdom, especially Dominator https://github.com/Pauan/rust-dominator. It’s faster than nearly all JS frameworks. The underlying rust-signals it’s based on is a fantastic crate. Unfortunately it’s not very well documented (check the prs for some wip docs). I got a frontend up and going with reactivity and nice styles using trunk and tailwindcss with daisyUI very quickly.

How does this compare to dominator?
