This is a companion repository to my Functional Scala Conference talk. The slides can be found here: https://docs.google.com/presentation/d/12EkZQKwi4cETRIsI5y0if1mG6GRuRxkeI8p7iMUBivc/edit?usp=sharing
There is a dummy database that you can start by running docker-compose up. Then you can open the root directory in your favorite editor, start a Metals project, go to src/main/scala/main.scala, edit the SQL query and watch the inferred types of res and row variables change.
Feel free to contact me if you have any questions or feedback!
