Methods

streamify(object, function)

Passes the function chunks of the object until there is none of the object left. streamify is a synchronous function.

var assert = require('assert')
  , streamify = require('../streamify').streamify
  , streamingWrite = require('../streamify').streamingWrite
  , fs = require('fs')
  , object = { a: 1, b: 2, c: 3}

var str = '';
streamify(object, function(data) { str += data; });
console.log(str);
// => {"a":1,"b":2,"c":3}

streamingWrite(filepath, object, callback)

Writes chunks of the object to the given filepath until there is none of the object left. When it finishes, it calls callback.

var str = '';
streamingWrite('./ACOOLFILE.txt', object, function(data) { str += data; }, function() {

  console.log(fs.readFileSync('./ACOOLFILE'));
  // => {"a":1,"b":2,"c":3}
});

Most of this was written by James Halliday, with a few small things by David Trejo.

TODOs

• allow a stream to be passed into streamify(object, stream)?
