Stream to Buffer

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

It will concatenate a raw stream to a Buffer, an ascii or utf8 encoded stream to a String, and an object mode stream to an Array.

Installing

npm install --save stream2buffer

API

var stream2Buffer = require('stream2buffer');
var fs = require('fs');
var Readable = require('stream').Readable;
var assert = require('assert');
 
// Raw stream
var rawStream = fs.createReadStream('hamlet.txt');
stream2Buffer(rawStream, function (err, buffer) {
  assert.ok(buffer instanceof Buffer);
  assert.ok(Buffer.isBuffer(buffer));
});
 
// utf8 encoded stream
var encodedStream = fs.createReadStream('hamlet.txt', {
  encoding: 'utf8' // would be the same with ascii here
});
stream2Buffer(encodedStream, function (err, buffer) {
  assert.ok(typeof buffer === 'string');
});
 
// object mode stream
var objectStream = new Readable({ objectMode: true });
var n = 10;
objectStream._read = function _read () {
  objectStream.push({ "hello": "world" });
  if (!n--)
    objectStream.push(null);
};
stream2Buffer(objectStream, function (err, buffer) {
  assert.ok(buffer instanceof Array);
  assert.ok(Array.isArray(buffer));
});

A fork of

Jonathan Ong's stream-to-buffer. I forked it because we disagree on how much stream-to-buffer must know to work properly.
