Part 2: youtube.com/watch?v=9xgOQh-Ppao Blog post: blog.rockthejvm.com/doobie/ Resources: The Cats Effect course: rockthejvm.com/p/cats-effect How to write your own string interpolator: youtube.com/watch?v=J6Vnn7aHYAk Value types in Scala: youtube.com/watch?v=xf3i4ZjrNs0 Doobie documentation: tpolecat.github.io/doobie/ 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.
