Option[] as type of field in case class
Additionally, I also like to use Refined, so that my names are actually NonEmptyStrings, and I'll usually go even farther and make a LastName type alias to NonEmptyString and a FirstName type alias to NonEmptyString so that I can legitimately return just Char as an initial, for example. That way parsing guarantees you're not just sending me empty stuff that is just as useless as an empty person, and also so that I don't accidentally put a FirstName where a LastName should go somewhere in my code.

Why there is still no ExpressJS-like alternative in Scala?
This example uses probably the most popular JSON library for Scala, Circe. There is another Scala library that lets us "be more specific with," or "refine," our types, called Refined. http4s doesn't provide any particular support for Refined, but Circe has a module integrating Refined, meaning that all of Circe's parsing, encoding, and decoding support is integrated with Refined. Putting together http4s' Circe support, Circe's generic codec derivation, and Circe's Refined integration, here's what I came up with:
