OBSOLETE: since node@18, there is now a stream.toArray() function
Concatenate a readable stream's data into a single array.

- raw-body for strings
var toArray = require('stream-to-array')
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); })
