Counter Example

use seed::{prelude::*, *};

// `init` describes what should happen when your app started.
fn init(_: Url, _: &mut impl Orders<Msg>) -> Model {
    Model::default()
}

// `Model` describes our app state.
type Model = i32;

// `Msg` describes the different events you can modify state with.
enum Msg {
    Increment,
}

// `update` describes how to handle each `Msg`.
fn update(msg: Msg, model: &mut Model, _: &mut impl Orders<Msg>) {
    match msg {
        Msg::Increment => *model += 1,
    }
}

// `view` describes what to display.
fn view(model: &Model) -> Node<Msg> {
    div![
        "This is a counter: ",
        C!["counter"],
        button![
            model,
            ev(Ev::Click, |_| Msg::Increment),
        ],
    ]
}

#[wasm_bindgen(start)]
pub fn start() {
    // Mount the `app` to the element with the `id` "app".
    App::start("app", init, update, view);
}

future	Asynchronous values.
helpers
prelude	Introduce El and Tag into the global namespace for convenience (El will be repeated often in the output type of components), and UpdateEl, which is required for element-creation macros, input event constructors, and the History struct. Expose the wasm_bindgen prelude.
shortcuts	This file exports helper macros for element creation, populated by a higher-level macro, and macros for creating the parts of elements. (attrs, style, events)
