<a href=”http://browsenpm.org/package/jsonstream”>JSONStream</a> (GitHub: <a href=”https://github.com/dominictarr/JSONStream”>dominictarr/JSONStream</a>, License: Apache) is a module by <a href=”https://github.com/dominictarr”>Dominic Tarr</a> for streaming <code>JSON.parse</code> and <code>JSON.stringify</code>.
<pre><code>npm install jsonstream
<h2 id=”usage”>Usage</h2>
<pre><code>var request = require(‘request’),
JSONStream = require(‘JSONStream’),
es = require(‘event-stream’)

var parser = JSONStream.parse([‘rows’, true]),
req = request({url: ‘http://isaacs.couchone.com/registry/_all_docs’}),
logger = es.mapSync(function (data) {
return data;

request({url: ‘http://isaacs.couchone.com/registry/_all_docs’})
.pipe(es.mapSync(function (data) {
return data;

It can also integrate with <a href=”http://gulpjs.com/”>gulp.js</a> very nicely. The really cool thing for me is that you can react to specific nodes in the data structure vs having to seek them out and loop over them manually.

Are you dealing with large JSON structures on your project?
