Global Signals

Global Signals behave like Signals but you declare them statitically and you don’t need to pass them through props or context as you can just import it. Main use case is for apps, not libraries.

Example

static COUNT: GlobalSignal<usize> = Signal::global(|| 0);

fn app() -> Element {
    let onclick = move |_| {
        *COUNT.write() += 1; // Modify the global signal, as if it was a normal signal
    };

    rsx!(
        label {
            onclick,
            "{COUNT}" // Read the global signal
        }
        SomeOtherComp {}
    )
}

#[component]
fn SomeOtherComp() -> Element {
    rsx!(
        label {
            "{COUNT}" // We can use the global signal here again
        }
    )
}
