This is the backend to get the exchange rates over time for ARS-USD.

To run this project you will need:

• Ruby version: 3.0 or higher

• Rails

• System dependencies:

  • Postgres database running. Configure connection string on database.yml
  • Sidekiq running: this allows to run a job that will fetch exchange rates every 10 minutes.
  • Whenever: this allows to set up a cron job on the machine that will run the job to fetch exchange rates.
  • Redis running: whenever will enqueue the job into a redis, and sidekiq will fetch the job from the queue and hit the endpoint.

Steps to run this project:

1. Create a new postgres database and configure the connection.
2. Run rails migrations into the db using rails db:migrate.
3. Run whenever --update-crontab to set up the cron job in your computer.
4. Run bundle exec sidekiq to start running sidekiq jobs. You can check it's running at http://0.0.0.0:3000/sidekiq/.
5. Verify everything is running. Every 10 minutes the job will hit the endpoint to fetch the new exchange rates. You can run the job yourself in the rails console (enter with rails console) and then running FetchDolarDataJob.perform_now.
6. Hit the endpoint http://0.0.0.0:3000/dolar to get the current rate. Hit http://0.0.0.0:3000/dolar to get the rates over time.
