watch_throttled
A throttled version of watch.
Demo
Usage
use leptos::*;
use leptos::logging::log;
use leptos_use::watch_throttled;
pub fn Demo() -> impl IntoView {
let (source, set_source) = create_signal(0);
watch_throttled(
move || source.get(),
move |_, _, _| {
log!("changed!");
},
500.0,
);
view! { }
}This really is only shorthand shorthand for watch_with_options(deps, callback, WatchOptions::default().throttle(ms)).
Please note that if the current component is cleaned up before the throttled callback is called, the throttled callback will not be called.
There's also watch_throttled_with_options where you can specify the other watch options (except filter).
use leptos::*;
use leptos::logging::log;
use leptos_use::{watch_throttled_with_options, WatchThrottledOptions};
pub fn Demo() -> impl IntoView {
let (source, set_source) = create_signal(0);
watch_throttled_with_options(
move || source.get(),
move |_, _, _| {
log!("changed!");
},
500.0,
WatchThrottledOptions::default().leading(true).trailing(false),
);
view! { }

Server-Side Rendering
On the server the callback
will never be called except if you set immediate to true in which case the callback will be
called exactly once.
