What was done:
Backend
Implemented a GraphQL query to fetch exchange rates.
Integrated data source from the Czech National Bank official API.
Implemented caching in PostgreSQL with a 5-minute expiration:
If the cached rates are older than 5 minutes, they are fetched again from the bank.
Otherwise, data is served from the database.
Added a migration to support exchange rate storage.
Frontend
Created a table component to display exchange rates.
Implemented a time tracker to show when the rates were last updated.
Used GraphQL query to fetch data.
