yahoo-finance is Yahoo Finance historical quotes and snapshot data downloader written in Node.js.
The library handles fetching, parsing, and cleaning of CSV data and returns JSON result that is convenient and easy to work with. Both callback (last parameter) and promises (using Bluebird) styles are supported.
