Route To Get Days Difference

[bhaden94]

Currently I calculate days difference on the frontend. I want to move this to the backend. The route needs to handle all states/countries in one GET.

There can also be a choice of how many days difference to get. For example we could get the difference in the last day for each state/country or we could get the difference in the last 7 days for each state/country.

One option: this would move all calculation to the BE which would be nice and fast

• parameters sent to backend: State/Country object, days difference, property name(maybe, will start by just doing active)
  • State/Country object: This would come in as a LinkedHashMap(to keep order) that would look like this

    • {
      alabama: 'Alabama',
      alaska: 'Alaska',
      arizona: 'Arizona',
      etc...
      }

    • We could then build a map where the key is state/country name and the value is the difference

      • {
        Alabama: 1200,
        Alaska: 1000,
        Arizona: -500
        }

Another easier option: This would keep calculations on the FE, but the network data should still be pretty small.

• Return the most recent DB entry and the one that is daysDifference away
