A FUNCTIONAL SCALA STACK FOR 2020
summary
Builds a tiny backend that records likes for programming languages with a simple schema (languages, likes) and a working HTTP endpoint bound on port 8080. Uses tapir + http4s to describe endpoints as values, doobie transact to compile ConnectionIO upserts and a sequenced insert for likes, and generates OpenAPI -> Swagger UI docs. Demo inserts show 3 likes across 2 language rows, uses a bearer token "1234" for auth, and the live demo runs successfully.
