EconDataReader

Up to date remote economic data access for ruby, using Polars dataframes.

This package will fetch economic and financial information from several different sources.

Installation

Add this line to your application's Gemfile:

gem 'econ_data_reader'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install econ_data_reader

Configuration

Some data sources will require the specification of an API key. These keys should be provided as part of a configuration file, e.g., config/econ_data_reader.rb

EconDataReader::Fred.configure do |config|
  config.fred_api_key = '1234567890ABCDEF'
    OR
  config.fred_api_key = File.read(File.join('','home', 'user', '.fred_api_key.txt'), 16)
end

EconDataReader::Bls.configure do |config|
  config.bls_api_key = '8675309-1111-1111-ABCD'
end

EconDataReader::Nasdaq.configure do |config|
  config.nasdaq_api_key = 'YOUR_API_KEY_HERE'
end

Usage

EconDataReader::BankOfCanada.new('IEXE0102').fetch

EconDataReader::Fred.new('GS10').fetch 

EconDataReader::Bls.new('LNS14000006')

EconDataReader::Nasdaq.new('WIKI/AAPL').fetch

Contributing

Others are welcome to contribute to the project.

The following conventions are intended for this project.

• Different sources are intended to reside in different classes.
• API keys (if needed) should be able to be set in the single configuration file.
• Series should be able to be identified via a single unique string, provided in the constructor.
• When fetched, the dataset may be filtered based on optional (hash) arguments.
• Output should be provided in a consistent DataFrame format (currently Polars::DataFrame).
