var toArray = require('stream-to-array')
toArray([stream], [callback(err, arr)])
Returns all the data objects in an array. This is useful for streams in object mode if you want to just use an array.
var stream = new Stream.Readable()
toArray(stream, function (err, arr) {
assert.ok(Array.isArray(arr))
})
If stream is not defined, it is assumed that this is a stream.
var stream = new Stream.Readable()
stream.toArray = toArray
stream.toArray(function (err, arr) {
})
If callback is not defined, then it returns a promise.
toArray(stream)
.then(function (parts) {
})
If you want to return a buffer, just use Buffer.concat(arr)
toArray(stream)
.then(function (parts) {
var buffers = []
for (var i = 0, l = parts.length; i < l ; ++i) {
var part = parts[i]
buffers.push((part instanceof Buffer) ? part : new Buffer(part))
}
return Buffer.concat(buffers)
})
