data-stream v0.2.3

#data-stream

A Promise like data-stream implementation.

##Installing

• npm:

    $ npm install --save data-stream

• bower

    $ bower install --save data-stream

##Documentation

const Stream = require('data-stream')
const s = new Stream()

###Stream Class

The Stream Class is responsible to receive the data from the broadcaster

####Methods

• notify(data: any) : None

  Send information to this and all child streams

• then(callback: Function) : Stream

  Generates a child stream that applies a extra callback

• map(callback: Function) : Stream

  Just like then, but applies the callback to each element of the data instead of to the data itself

Examples:

Setting up streams:

const Stream = require('data-stream');
const s = new Stream();
let stream1 = s.then(() => console.log("stream 1 exec 1"))
		.then(() => console.log("stream 1 exec 2"))
		.then(() => console.log("stream 1 exec 3"));
let stream2 = s.then(() => console.log("stream 2 exec 1"))
		.then(() => console.log("stream 2 exec 2"))
		.then(() => console.log("stream 2 exec 3"));
s.notify();
//stream 1 exec 1
//stream 1 exec 2
//stream 1 exec 3
//stream 2 exec 1
//stream 2 exec 2
//stream 2 exec 3

Transforming data:

const Broadcaster = require('data-stream');
const s = new Stream();
s.map((el) => el+1)
		.then(data => console.log(data));
s.notify([1,2,3]);
//[2,3,4]

##Why ? this package was built to easily manage asynchronous data between a service and several controllers on angular.
