flow-pow
Transform stream factory to exponentiate numeric data stream values according a specified power.
Installation
$ npm install flow-pow
API
To create a stream factory,
var powerStream = ;// Create a new factory:var pStream = ;
pStream.exponent( [value] )
This method is a setter/getter. If no value
is provided, returns the configured exponent
; default is 1
. To set the exponent
,
pStream;
pStream.stream()
To create a new power stream,
var stream = pStream;
Usage
Methods are chainable.
;
Examples
var eventStream =pStream = ;// Create some data...var data = 1000 ;for var i = 0; i < datalength; i++data i = Math;// Create a readable stream:var readStream = eventStream;// Create a new power stream:var stream =;// Pipe the data:readStream;
To run the example code from the top-level application directory,
$ node ./examples/index.js
Tests
Unit tests use the Mocha test framework with Chai assertions.
Assuming you have installed Mocha, execute the following command in the top-level application directory to run the tests:
$ mocha
All new feature development should have corresponding unit tests to validate correct functionality.
