This video is for the advanced Scala programmer. We learn how to interact with a database in a purely functional way with Scala and Doobie, one of the best libraries in the Scala ecosystem. This is the first part of a 2-part series, where we set up an initial project with PostgreSQL as a Docker container which we will use to test various features of Doobie within Scala.

We learn how to
retrieve values from the database
generate keys
run joins
programmatically generate queries
add support for custom types in Doobie with type classes
and many more.
