Streaming saving file


Streaming data to file and save it using Stream.(the module will make directory itself if the directory is not exist).

Install

``
npm install file-save
`

Example

`javascript
var fileSave = require('file-save');

// the first line will create a writeStream to the file path
fileSave('sample/test')
.write('this is the first line', 'utf8')
.write('this is the second line', 'utf8', function() {
console.log('writer callback')
})
.end('this is the end')
.error(function() {
console.log('error goes here')
})
.finish(function() {
console.log('write finished.')
})
`

Usage

`
fileSave()
`

file-save module will build a write stream to the file, and automatically make directory if the directory is not exist and need to create.

Chaining methods

#### .write(chunk, [encoding], [callbak])

- chunk (string)
- encoding (string): like the encoding settings in writeable stream. http://nodejs.org/api/stream.html#stream_writable_write_chunk_encoding_callback
- callback (function): callback function settings in writeable http://nodejs.org/api/stream.html#stream_writable_write_chunk_encoding_callback

#### .end([string], [encoding], [callback])

Same as .write method, but string is also optional.
