mega65-adventure VS yew

What are you on about, can you clarify? Rust can compile in no-std/embedded style just as fine (or better) than C can for basically any ARM or RISCV based processor, and quick googling shows this hal for nearly all pi needs and even MEGA65 is "as supported" (read: not at all officially by anything, fan-only) as any current C compiler. Setting up rust for a new target, so long as the code-gen is supported somehow by LLVM, LLVM plugin, LLVM IR transpiler (and maybe libgcc-jit sort of soon) is just as painful or unpainful as setting up a whole team to work via C/C++ with comparable testing harnesses. This doesn't mean easy and is an area Rust is still improving rapidly by the various enterprise agencies (Ferrous systems, Oxide, more I can't remember...) who specifically want to bring rust to such low end hardware because frankly both C and C++ suck with vendor proprietary tool chains and quirks.

Rust? It's built clean from the ground up. The crates.io registry is full of modern, safe, composable libraries. You've got Axum, Rocket and Actix for backends, Leptos, Dioxus, and Yew for frontend, and more. Every library you use follows the same philosophy: safety, performance, and zero tolerance for ambiguity.

> To my knowledge there is not a Vue/React-WASM-type framework out there yet or any framework for building web apps in WASM (without starting from a blank canvas).

Not sure if these qualify, but these Rust web frameworks use wasm:

https://leptos.dev/

https://yew.rs/

Yew

This has already been done; there are multiple languages/frameworks that compile directly to WASM with no JS such as https://yew.rs/

> You still need to access the DOM, which can't be done directly from WASM. Maybe someday it will happen?

You can access the DOM through JavaScript glue. These Rust WASM frameworks do that:

- Leptos: https://www.leptos.dev/

- Sycamore: https://sycamore.dev/

- Yew: https://yew.rs/

- Dioxus: https://dioxuslabs.com/

> Okay, so use canvas instead and do all UI inside WASM?

You can do that too. That's what this VB6 clone written in C# and compiled to WebAssembly does:

- https://github.com/BAndysc/AvaloniaVisualBasic6

> vague "JavaScript limitations"

It's not vague. Despite 28 years of effort optimizing JavaScript, WebAssembly outperforms JavaScript:

[package] name = "wasm-dev" version = "0.1.0" edition = "2021" [dependencies] yew = { git = "https://github.com/yewstack/yew/", features = ["csr"] }

Yew is a framework for creating reliable and efficient web applications. Yew

I coded up a game of life implementation in rust and web assembly using https://yew.rs/ as an effort to sharpen my rust skills and it resulted as a fun toy. You can find the source here: https://gitlab.com/reedrichards/wvdom Enjoy!
