module Y2018.M05.D18.Exercise where
-- Before we insert new articles, let's step back in time for a moment. Recall
import Y2018.M04.D09.Exercise
where we uploaded tags, we uploaded a sample set of 10 tags. There are a lot
more tags than 10 for the World Policy Journal. Today we're going to find out
how many.
The REST endpoint for the tags is as follows:
import Y2018.M04.D11.Exercise (PageNumber)
tagEndpoint :: PageNumber -> FilePath
tagEndpoint pn = ""
++ show pn
-- The JSON format we already know and parse (see above exercise) and the
-- tags are exhausted when the Value returned is the empty list.
-- How many tags are there for this REST endpoint?
downloadTags :: IO [Tag]
downloadTags = undefined
-- You may want to use some pagination function to help define downloadTags
-- hint: see definitions in Y2018.M04.D13 for downloading packets and use
-- a similar approach
{-- BONUS -----------------------------------------------------------------
Create an application that downloads all the tags from the REST endpoint and
then uploads those tags to a PostgreSQL data table as described in the module
-- BONUS-BONUS ------------------------------------------------------------
Create an application that does the same thing, but for categories this time.
See Y2018.M04.D06 for information on categories (very (VERY)) much like tags.
