Amazon Review Stream

Node Transform Stream for parsing the SNAP Amazon Review datasets into JavaScript objects.

Usage

Assuming you've saved a SNAP dataset locally.

var fs = require('fs'),
    reviews = require('amazon-review-stream');

var reviewStream = fs.createReadStream('./Arts.txt.gz').pipe(reviews());

reviewStream.on('data', function(item) {
    console.log('Product: %s', item.product.title);
    console.log('Review: %s', item.review.summary);
});

Of course if you're a very patient person, you could just stream directly from the SNAP site. Keep in mind this below sample will pull down 4.4GB of data if you sit through it...

var request = require('request'),
    reviews = require('amazon-review-stream');

var reviewStream = request('http://snap.stanford.edu/data/amazon/Books.txt.gz').pipe(reviews());

reviewStream.on('data', function(item) {
    console.log('Review: %s', item.review.summary);
});
