method-throttle

throttles a method for a specific time

Installation

    npm install --save method-throttle

Usage

Delay your methods execution by defining an interval of idle time.

var throttle = require( 'method-throttle' );
 
var method = throttle(function ( a, b, c ){
    // your code as usually
}, 1000 );
 
method( null, null, 1 );
method( null, null, 1 );
method( null, null, 1 );
method( null, null, 1 );
 
setTimeout( method, 1500 );
 
// function provided into throttle would run only twice!
 

Example use case:

Imagine that you want to register how many times an user scrolls a page. If you place an event listener on window.scroll, you would have a ton of data since almost all browsers fire those events whenever page is modified / rendered.

 
var timesScrolled = 0;
 
window.on( 'scroll', function () {
    timesScrolled++;
});
 

That would not be a bottleneck, but for most advanced use cases, you would be some how pissed off.

With throttle you can limit how many times, within a provided interval of time, a method could run:

var throttle = require( 'method-throttle' );
var timesScrolled = 0;
 
window.on( 'scroll', throttle(function () {
    timesScrolled++;
}, 1000 ));
 

Now, if you were always scrolling, you would get at a maximum of 60 count!!
