**Sauron** is a versatile web framework and library for building client-side and/or server-side web applications
with strong focus on simplicity. It is suited for developing web application which uses progressive rendering.


#### Counter example
In your `src/lib.rs`
```rust
use sauron::html::text;
use sauron::prelude::*;
use sauron::{node, Cmd, Application, Node, Program};

#[derive(Debug)]
pub enum Msg {
    Increment,
    Decrement,
}

pub struct App {
    count: i32,
}

impl App {
    pub fn new() -> Self {
        App { count: 0 }
    }
}

impl Application<Msg> for App {
    fn view(&self) -> Node<Msg> {
        node! {
            <main>
                <input type="button"
                    value="+"
                    key="inc"
                    on_click=|_| {
                        Msg::Increment
                    }
                />
                <div class="count">{text(self.count)}</div>
                <input type="button"
                    value="-"
                    key="dec"
                    on_click=|_| {
                        Msg::Decrement
                    }
                />
            </main>
        }
    }

    fn update(&mut self, msg: Msg) -> Cmd<Self, Msg> {
        match msg {
            Msg::Increment => self.count += 1,
            Msg::Decrement => self.count -= 1,
        }
        Cmd::none()
    }
}

#[wasm_bindgen(start)]
pub fn main() {
    Program::mount_to_body(App::new());
}
```
`index.html`
```html
<html>
  <head>
    <meta content="text/html;charset=utf-8" http-equiv="Content-Type"/>
    <title>Counter</title>
    <style type="text/css">
        body { font-family: verdana, arial, monospace; }
        main {
            width:30px;
            height: 100px;
            margin:auto;
            text-align: center;
        }
        input, .count{
            font-size: 40px;
            padding: 30px;
        }
    </style>
    <script type=module>
        import init from './pkg/counter.js';
        await init().catch(console.error);
    </script>
  </head>
  <body>
  </body>
</html>
