collect-all

DEPRECATED. This package has been replaced by stream-read-all which does the same job but with a Promises interface.

collect-all

Returns a stream which fires a callback and becomes readable once all input is received.

By default the callback is invoked with a Buffer instance containing all concatenated input. If you set the option { objectMode: true } the callback is invoked with an array containing all objects received.

collectAll([callback], [options]) ⇒ Duplex ⏏

Kind: Exported function

Param	Type	Description
[callback]	function	Called once with the collected input data (by default a Buffer instance, or array in objectMode.). The value returned by this callback function will be passed downstream.
[options]	object	Stream options object, passed to the constructor for the stream returned by collect-all. If the callback function supplied returns a non-string/buffer value, set options.objectMode to true.

Example An example command-line client script - string input received at stdin is stamped with received then written to stdout.

var collectAll = require('collect-all')
process.stdin
  .pipe(collectAll(function (input) {
    input = 'received: ' + input
    return input
  }))
  .pipe(process.stdout)

An object-mode example:

var collectAll = require('collect-all')
 
function onAllCollected (collected) {
  console.log('Objects collected: ' + collected.length)
}
 
var stream = collectAll(onAllCollected, { objectMode: true })
stream.write({})
stream.write({})
stream.end({}) // outputs 'Objects collected: 3'
