debounce
Delay function calls until a set time elapses after the last invocation
Install
npm install debounce
Usage
import debounce from 'debounce';
function resize() {
console.log('height', window.innerHeight);
console.log('width', window.innerWidth);
}
window.onresize = debounce(resize, 200);
(You can also use const debounce = require('debounce')
)
To later clear the timer and cancel currently scheduled executions:
window.onresize.clear();
To execute any pending invocations and reset the timer:
window.onresize.flush();
API
debounce(fn, wait, options?)
Creates a debounced function that delays execution until wait
milliseconds have passed since its last invocation.
Set the immediate
option to true
to invoke the function immediately at the start of the wait
interval, preventing issues such as double-clicks on a button.
The returned function has a .clear()
method to cancel scheduled executions, and a .flush()
method for immediate execution and resetting the timer for future calls.
