just-debounce

just a basic debounce function

changes

• 1.1.0: added typescript definitions

Why?

I searched npm and the first 3 pages of results for "debounce" did not have a small correctly implemented version of debounce

Usage

arguments

• fn: the function to debounce
• delay: debounce delay in ms
• atStart: if true, the function will be called at the beginning of the delay rather than the end

• guarantee: additional calls to debounced function will not reset they delay. This guarantees that if the function is called frequently, it will fire once every delay rather than waiting for a break in calls.

  var db = require('just-debounce');
  
  var debounced = db(function (v) {
  console.log(v);
  }, 100);
  
  debounced('hi');
  debounced('hi');
  // logs 'hi' once after 100ms
  

  var db = require('just-debounce');
  
  var debounced = db(
  function (v) {
  console.log(v);
  },
  100,
  true
  );
  
  debounced('hi');
  debounced('hi');
  // logs 'hi' once right away, but not a second time. calling after 100ms will log again
  

  var db = require('just-debounce');
  
  var debounced = db(
  function (v) {
  console.log(v);
  },
  100,
  false,
  true
  );
  
  debounced('hi');
  setTimeout(function () {
  debounced('hi2');
  }, 80);
  
  // logs 'hi2' once 100ms after the first call to debounced
