just-debounce

just a basic debounce function

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
  • at_start: if true, the function will be called at the beginning of the delay rather than the end
  • guarantee: ensures the time before the next call the fn is not greater \ than the delay period.

    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
