Tiny helper library to extract an ASIN/ISBN number from an Amazon URL or create a (optionally localized) Amazon URL out of an ASIN/ISBN.
npm install amazon-helpers
or
yarn add amazon-helpers
Just require the library like any other npm module:
var amazonHelpers = require('amazon-helpers');
amazonHelpers.getIdent('http://www.amazon.com/gp/product/B000MTST70/')
=> B000MTST70
amazonHelpers.getProductUrl('B000MTST70')
=> http://www.amazon.com/dp/B000MTST70
You can specify a TLD as second argument to convert your URL to another country
amazonHelpers.getProductUrl('http://www.amazon.com/dp/B000MTST70', 'co.uk')
=> http://www.amazon.co.uk/dp/B000MTST70
Attention: The library does not check if the product exists in the given TLD!
amazonHelpers.getIdentByUrl('http://amazon.com/gp/product/B00L3KNWBU')
=> { asin: 'B00L3KNWBU', tld: 'com' }
