pebounce

debounce used to ignore most of my requests, so I found something more promising.

Install

$ npm install pebounce

Usage

import pebounce from 'pebounce';

const expensiveCall = async input => input;

const debouncedFn = pebounce(expensiveCall, 200);

for (const number of [1, 2, 3]) {
	console.log(await debouncedFn(number));
}
//=> 3
//=> 3
//=> 3

API

pebounce(fn, wait, [ immediate || false ])

Creates and returns a new debounced version of the passed function that will postpone its execution until after wait milliseconds have elapsed since the last time it was invoked.

fn

Type: Function Promise-returning/async function to debounce.

wait

Type: number Milliseconds to wait before calling fn.

immediate

Type: object

Pass true for the immediate parameter to cause debounce to trigger the function on the leading edge instead of the trailing edge of the wait interval. Useful in circumstances like preventing accidental double-clicks on a "submit" button from firing a second time.

The pebounced function returned has a property 'clear' that is a function that will clear any scheduled future executions of your function.

The pebounced function returned has a property 'flush' that is a function that will immediately execute the function if and only if execution is scheduled, and reset the execution timer for subsequent invocations of the debounced function.
