Nectar - Rust-like React framework compiling to WebAssembly

Show HN: Nectar, a Rust-like React that compiles to WebAssembly

Nectar reimagines web development by eliminating JavaScript dependencies in favor of a single, high-performance WebAssembly binary. Inspired by Rust, this framework compiles your entire application logic, state, and rendering into one file, removing the need for npm, node_modules, or complex build tools. With O(1) signal updates, a built-in borrow checker for compile-time safety, and a runtime smaller than 10 KB, Nectar offers a streamlined path from code to deployment. Developers can write less code, ship faster, and achieve zero virtual DOM overhead while leveraging familiar React-like syntax for modern web apps.

Your entire app — logic, state, rendering — runs in WASM. JavaScript is reduced to a 10 KB syscall layer.

    This is neat. It's like a framework and language in one. Congrats on the launch! The tooling for it feels quite novel.

    I get the allure of having zero dependencies but... the reason why I have dependencies in the first place is because the ecosystem provides tons of functionality out of the box. Do you want the language/framework to provide all the functionality?

    The landing page's main value prop is removing the dependency on JS. Thing is... I don't hate JS. Typescript has quite a lot of fans.

    I feel like you should demonstrate performance metrics or app size or just some other value prop other than hating on Javascript.

    How is this different / better than Leptos or Dioxus?

    Nice! Heads up that unfortunately the demos don't appear to scroll on mobile
