Reversible

Reverse Stream data chunks!

install:
``bash
$ npm install reversible
`

include in your project:
`javascript
var reverse = require('reversible')
`

Simple buffer example:
`javascript
var Readable = require('stream').Readable

var values = ['one', 'two', 'three', 'four', 'five']
, readIndex = 0

var readable = new Readable

readable._read = function () {
var index = readIndex++, value = values[index]
if (value !== undefined) value += '\n'
readable.push(value)
}

readable
.pipe(reverse())
.pipe(process.stdout)
`

Example reading file splitting on new line:
`javascript
var fs = require('fs')
, splitStream = new (require('stream').PassThrough)()

splitStream._transform = function (chunk, enc, next) {
String(chunk).split('\n').forEach(function (piece) {
splitStream.push(piece)
})
next()
}

fs.createReadStream('file.txt')
.pipe(splitStream)
.pipe(reverse())
.pipe(process.stdout)
`

You can also pipe objects by passing in the objectMode flag:

`javascript
var stream = require('stream')
, readable = new stream.Readable()
, stringify = new stream.Transform()
, index = 0
, data = [
{ no: 'one' }
, { no: 'two' }
, { no: 'three' }
, { no: 'four' }
, { no: 'five' }
]

readable._read = function () {
this.push(data[index++])
}
readable._readableState.objectMode = true

stringify.start = true
stringify._writableState.objectMode = true
stringify.write = function (chunk, enc, next) {
var data = JSON.stringify(chunk)

if (stringify.start) {
stringify.push('[')
stringify.start = false
} else {
data = ',' + data
}

stringify.push(data)
}
stringify._flush = function () {
stringify.push(']')
}

readable
.pipe(reverse({ objectMode: true }))
.pipe(stringify)
.pipe(process.stdout)
