Stream to Array

OBSOLETE: since node@18, there is now a stream.toArray() function

Concatenate a readable stream's data into a single array.

API

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) {
    const buffers = parts
      .map(part => util.isBuffer(part) ? part : Buffer.from(part));
    return Buffer.concat(buffers);
  })
