Time: 27th of October, 9-12AM SF time (19-21PM CET) - 3h
Title: Exposing an HTTP API using Scala 3
Description:

It's about time to leverage the new features available in Scala 3! A number of libraries have been updated, making it possible to write fully-functional applications using the latest Scala version.

We'll create a basic application from scratch, exposing an HTTP API, using the following Scala 3 features:

• enums to define data structures
• opaque types for even more type-safety
• typeclass derivation using the `derives` keyword
• extension methods
• new braceless syntax

The following Scala libraries will be involved:

• tapir for describing web endpoints
• http4s as the HTTP server implementation
• cats-effect to control effects and for asynchronous programming

If you've been using Scala 2 before, or if you are completely new to Scala - come and see how functional programmings works our in practice! No prior Scala experience is required.

A starting repository and setup instructions will be provided for the attendees before the workshop.
