concat-stream-callback

Callback wrapper for concat-stream providing errors. Simplifies converting a
Readable stream into a node-style callback.

Example

$3

``javascript
var concatStreamCallback = require('concat-stream-callback')

var write = concatStreamCallback(function(err, data) {

if (err) return console.error(err);

// data will be [1,2,3,4,5,6]
console.log(data);
})

write.write([1,2,3])
write.write([4,5,6])
write.end()
`

$3

`javascript
var fs = require('fs')
var concatStreamCallback = require('concat-stream-callback')

var readStream = fs.createReadStream('cat.png')

var writeStream = concatStreamCallback(readStream, function(err, imageBuffer) {
// handle your error appropriately here, e.g.:
if (err) return console.error(err)

// imageBuffer is all of cat.png as a node.js Buffer
console.log(imageBuffer);
}

readStream.pipe(writeStream)
`

Wraps concat-stream

This module leverages the power provided by Max Ogden's
concat-stream. All of
concat-stream's functionality is available (except instantiation with new -
it is recommended to avoid this).

Usage

`javascript
var concatStreamCallback = require('concat-stream-callback');
`

See /test and concat-stream for
more example usage.

$3

#### readable

An optional Readable instance to attach error handlers to.

#### opts

Optional options passed through to concat-stream. See
here
for details.

#### cb

`javascript
function (err, result) {}
`

Required callback which executes if readable emits an 'error'`, or once after
the stream has been completely read.
