Minimal server-driven UI in Rust.

NanoRust renders HTML on the server, keeps state in Rust, and updates the browser through SSE plus small DOM patches. No WASM, no hydration step, no client framework runtime.

Example

use nanorust::prelude::*;
use nanorust::{component, signal};

signal!(Counter, i32, 0);

component! {
    CounterWidget {
        <div nano:id="counter-widget">
            <h2>"Counter: " $count</h2>
            <button on:click=increment>"+"</button>
        </div>
    }

    action increment() {
        Counter::update(|n| *n += 1);
    }
}

What It Is

• SSR-first
• signal-based state
• server actions
• SSE updates
• tiny client script

Run
