squark

Virtual DOM implemention and application definition inspired from HyperApp.

squark-macros

Crate that providing JSX like macro by proc_marco and pest parser.

Syntax

view! {
    <button class="clear-completed" onclick={ handler((), move |_| { Some(Action::Submit) }) }>
        Submit
    </button>
}

squark-stdweb

Squark runtime implemention for web browser with usinng stdweb.

Here is full example of counter app!

                state.count -= 1;
            },
        };
        state
    }

    fn view(state: State) -> View<Action> {
        view! {

                { text(state.count.to_string()) }
                <button onclick={ handler((), |_| Some(Action::Increment)) }>
                    increment

                <button onclick={ handler((), |_| Some(Action::Decrement)) }>
                    decrement
                </button>
            </div>
        }
    }
}

fn main() {
    stdweb::initialize();
    Runtime::<CounterApp>::new(
        document().query_selector("body").unwrap().unwrap(),
        State::new(),
    ).start();
    stdweb::event_loop();
}
