Hirola is a declarative frontend framework that is focused on simplicity and reactivity.


  1. KISS: A simple and declarative way to build frontend UIs in rust.
  2. Make it easy to read, extend and share code.
  3. Frp signals allowing fine-grained reactivity.
  4. Familiarity: Uses rsx which is very similar to jsx.


We are going to create a simple counter program.

cargo new counter

With a new project, we need to create an index file which is the entry point and required by trunk

cd counter

Create an index.html in the root of counter. Add the contents below

<!DOCTYPE html>
    <meta charset="UTF-8" />
    <title>Hirola Counter</title>

Lets add some code to src/main.rs

use hirola::prelude::*;
use hirola::dom::*;

fn counter() -> Dom {
    let count = Mutable::new(0i32);
    let decrement = count.callback(|s| *s.lock_mut() -= 1);
    let increment = count.callback(|s| *s.lock_mut() += 1);
    html! {
            <button on:click=decrement>"-"</button>
            <button on:click=increment>"+"</button>
fn main() {

Now lets run our project

trunk serve
