funkz-debounce

A lightweight and strongly typed debounce utility written in TypeScript.
It helps control how often a function is executed by delaying its execution until a specified amount of time has passed since the last call.

Installation

npm i funkz-debounce

Usage

import debounce from "funkz-debounce";

function handleInput(value: string) {
  console.log("Search:", value);
}

// Create a debounced version of the function
const debouncedSearch = debounce(handleInput, 500);

// Call multiple times, but it only triggers once after 500ms
debouncedSearch("apple");
debouncedSearch("banana");
debouncedSearch("orange");

Function Signature

debounce<T extends (...args: Array<unknown>) => void>(
    func: T,
    delay: number,
    immediate: boolean = false
): (...args: Parameters<T>) => void;

Parameters:

• func : The function to debounce.
• delay : The time (in milliseconds) to wait before executing.
• immediate : If true, run the function immediately on the first call, then ignore subsequent calls until the delay passes.

Example with Immediate Execution

const logClick = debounce(() => console.log("Clicked!"), 300, true);

document.addEventListener("click", logClick);

In this case, the function executes immediately on the first click, then ignores any other clicks for the next 300ms.
