For the demonstration, a exchange-rate-cbrf-ui project was made and deployed an online demonstration in the cloud.
For authorization, you can use the account superuser
with password SYS
For this project, I used the AdminLTE template, which I have already used in my projects more than once, for example info-chest or access-matrix.
On the main page, you can get a table of exchange rates...
... or download data from the official website of the Central Bank of the Russian Federation.
Two more pages have been created for demonstration purposes.
They show graphs of fluctuations in the exchange rate of different currencies for different time periods.
