Combatting Alert Fatigue by Prioritizing Malicious Intent
In 2023, data breaches surged 78% from zero-day and supply chain attacks, but developers are still buried under alerts that are unable to prevent these threats.
collect-all
Advanced tools
DEPRECATED. This package has been replaced by stream-read-all which does the same job but with a Promises interface.
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.
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'
