Geckoboard Ruby script

Ruby 3.2.1

This little Ruby script will generate and/or push the latest average bitcoin rate to a Geckoboard dashboard every 10 minutes.

I kept in mind the simplest and minimum amount of code. Also it has been written in a short amount of time. Meaning it still needs some work.

At first I thought doing it in Sinatra or Node/Express, but as the dashboard requires a computer to display its data I thought we could run a script locally. Although, if a server is needed the implementation should be easy.

At this moment it pushes Pounds, US Dollars, Euros and Reals.

Taking it further:

Store data to a remote database to display ratings over the time.
Use series parameter to create line charts.
Display all available currencies.
Display extra charts such as monitoring.
From this point I would move to a Rails API only app and work on tests.

How to use:

To view the dashboard: https://srmarquinho.geckoboard.com/dashboards/0DC18FF9ECFD3A4D

Clone this repository git clone https://github.com/srMarquinho/bitcoin-widget.

Install dependencies bundle

Set an ENV["GECKOBOARD_API_KEY"] environment or change GECKOBOARD_API_KEY constant with your Geckoboard api.

Change the constant INTERVAL_IN_SECONDS to change the time interval to push.

Run the script ruby app.rb to live update.

Difficulties:

I had difficulties and spent some time tying to get the hash in the example to work.

dataset = client.datasets.find_or_create('sales.gross', fields: [
  Geckoboard::MoneyField.new(:amount, name: 'Amount', currency_code: 'USD'),
  Geckoboard::DateTimeField.new(:timestamp, name: 'Time'),
])

unknown keyword: currency_code
