coin-scrapper

This is a very simple Node script that I made for a friend of mine grab all bitcoin quotes from a period of time and outputs the data in CSV format.

All that comes from MercadoBitcoin. I'm using their REST API.

Installation

To use this, you must have Node and NPM installed. I'm using Node v8.6.0 and npm 4.6.1 at this time.

Go to your terminal and inside the folder where the project lives, type:

npm i
npm link

Usage

coin-scrapper <initial_date> <final_date>

Note that all dates must be in the following format YYYY-MM-DD
