Experimental UI (web) framework

• Zero Rc<RefCell<_>> wrappers, mut-ate state directly
• Zero use_state hooks and etc
• Zero proc macros, components are really functions
• Rusty: use ownership to control components lifespans
• Event based, structured concurrency in mind
• Minimal API, reuse ready-made ecosystem

Examples

An interactive component with a button and click counter:

use {nau::prelude::*, wasm_bindgen::prelude::*};

#[wasm_bindgen(start)]
pub async fn start() {
    nau::app(clicker, "root").await;
}

async fn clicker(ui: Ui) {
    let button = ui.make_button("Click").onclick(|| ());
    let text = ui.make_div();
    let mut n = 0;
    loop {
        (&text).text(format!("clicked {n} times.."));
        button.event().await;
        n += 1;
    }
}
