sample-jsonstream.js

var stream = require('stream');
var JSONStream = require('JSONStream');

var inputStream = new stream.PassThrough();
var jsonStream = JSONStream.parse('*');
var finalStream = new stream.Writable({ objectMode: true });
finalStream._write = function (doc, encoding, done) {
  console.log(doc);
  done();
};

inputStream.pipe(jsonStream).pipe(finalStream);
inputStream.push('[{"a": 1},{"b" : 2},{"c": 3},');
inputStream.push('{"d": [4,5,6]}]');
inputStream.end();
