Objectives:

Roadmap 0:

• Get a barebones 'Hello World' API running.
• Get a working database set up.
• Create a table in that database with dummy data.
• Return data from that database.
• Set up a logging scheme for these APIs.

Roadmap 1:

• Create tables and data structures for users.
• Create tables and data structures for user account balances.
• Create tables and data structures for exchange rates.
• Create tables and data structures for past exchanges.
• Create a controller that gets users.
• Create a controller that gets exchange rates (seeded with dummy data for now).
• Create a controller that gets and creates exchanges.
• Set up a testing strategy.
• Test the business logic behind the currency exchanges.

Roadmap 2:

• Obtain an API key to either fixer.io or exchangeratesapi.io.
• Implement a service that fetches a currency rate from one of the chosen APIs.
• Save that information to a database.
• Create an endpoint to get currency rates from the database and fetch that record if it's less than 30 minutes old.
• If the currency record is 30 minutes old or older, update it with a new rate record instead.
• Develop unit tests for these services.

Roadmap 3:

• Implement an identity setup to allow existing users to sign in.
• Allow the user to perform currency exchanges using the currency API and record them to the database.
• Develop unit tests for these services.

Roadmap 4:

• Polish up deployment data support.
• Fix Seq integration.
