A distributed data scraping and processing framework

Usage no npm install needed!

<script type="module">
  import nodeIo from '';


Note: this library is no longer maintained.

I wrote in 2010 when node.js was still in its infancy and the npm repository didn't have the amazing choice of libraries as it does today.

Since it's now quite trivial to write your own scraper I've decided to stop maintaining the library.

Here's an example using request, cheerio and async.

var request = require('request')
  , cheerio = require('cheerio')
  , async = require('async')
  , format = require('util').format;

var reddits = [ 'programming', 'javascript', 'node' ]
  , concurrency = 2;

async.eachLimit(reddits, concurrency, function (reddit, next) {
    var url = format('', reddit);
    request(url, function (err, response, body) {
        if (err) throw err;
        var $ = cheerio.load(body);
        $('a.title').each(function () {
            console.log('%s (%s)', $(this).text(), $(this).attr('href'));

Happy scraping.
