§Global Signals
Global Signals are like Signals but you declare them statically 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
}
)
}
