UPCtoASIN.com -- A website to easily convert a UPC to an ASIN.

Features

1. There is an sqlite database used for caching lookups.
2. Requests to the Amazon API are throttled to 1 request/sec.

Installation

git clone [email protected]:AlexCline/upctoasin.com.git
cd upctoasin.com
npm install
make test
node app.js

Also needed is a file at conf/aws.conf with the following contents:

AWSAccessKeyId: YOURAWSACCESSID
AWSSecretKey: YOURAWSSECRETKEY
AWSTagId: YOURAWSASSOCTAGID

You'll also need to specify the path to XCode before you run npm install. This is needed for the sqlite3 module.

sudo xcode-select --switch /usr/bin

You'll need the following packages to build the required modules:

sudo yum install make
