We are building the frontend of our _application_ in Rust and rendering it to a canvas using egui.rs. For the web site we are using more "traditional" tech, as you've noticed.
I am not a big fan of the complexity of modern web sites (including our own), which is exactly why I created egui. However, it is targeted at web apps, not web sites.
I'm very curious how well this is working for you in practice, since I've been thinking about what it would look like to share a single Rust UI implementation across a webapp and native apps.
Putting the UI in a canvas elements have some distinct drawbacks (https://github.com/emilk/egui/tree/master/crates/eframe#prob...) but for us it is definitely worth it. Having one unified codebase for our web app and native app, and having it all in Rust, is just amazing.
We're currently working on a 3D renderer based on wgpu (https://github.com/gfx-rs/wgpu) that we will likewise use for both web and desktop.
