Quickstart example

Below you'll find a simple counter example, demonstrating how to read and write to shared state.

#![allow(unused)]
fn main() {
extern crate yewdux;
extern crate yew;
use yew::prelude::*;
use yewdux::prelude::*;

#[derive(Default, Clone, PartialEq, Store)]
struct State {
    count: u32,
}

#[function_component]
fn ViewCount() -> Html {
    let (state, _) = use_store::<State>();
    html!(state.count)
}

#[function_component]
fn IncrementCount() -> Html {
    let (_, dispatch) = use_store::<State>();
    let onclick = dispatch.reduce_mut_callback(|counter| counter.count += 1);

    html! {
        <button {onclick}>{"+1"}</button>
    }
}

#[function_component]
fn App() -> Html {
    html! {
        <>
        <ViewCount />
        <IncrementCount />
        </>
    }
}
}

Additional examples

Complete working examples can be found in the examples folder of github.

To run an example you'll need to install trunk (a rust wasm bundler), then run the following command (replacing [example] with your desired example name):

    trunk serve examples/[example]/index.html --open
