Chunking
========

Simple Task Chunking

About
-----

Chunking is a very small JavaScript library, providing the capability
to chunk (aka rate limit or throttle) method calls by first absorbing
arguments to a function up to a certain amount of time and then finally
emitting the arguments to an underlying function.

Installation
------------

``shell
$ npm install chunking
`

Usage
-----

`js
const chunking = require("chunking")
const expect = require("chai").expect

const receive = (items) => {
expect(items).to.be.deep.equal([ "foo", "bar", "baz", "quux" ])
console.log(items)
}

let notify = chunking({
reset: (ctx) => { ctx.items = [] },
absorb: (ctx, items) => { items.forEach((item) => ctx.items.push(item)) },
emit: (ctx) => { receive(ctx.items) },
delay: 2 * 1000
})

notify([ "foo", "bar" ])
notify([ "baz" ])
notify([ "quux" ])
``
