Explore the event-driven architecture (EDA) in a purely functional way, mainly powered by Fs2 streams in Scala 3.

In the same spirit of Practical FP in Scala, we will develop a distributed system that meets the requirements of a modern software architecture capable of processing billions of events per day at scale using Apache Pulsar.

It also includes a Web Sockets service powered by Http4s, and a Web application written in ELM.

Although the application picks a particular design and implementation, the concepts should easily translate to other designs in the same space that can be built on top of Apache Kafka, Rabbit MQ, or other message brokers.

Practical FP in Scala: A hands-on approach, is a book for intermediate to advanced Scala developers. Aimed at those who understand functional effects, referential transparency and the benefits of functional programming to some extent but who are missing some pieces to put all these concepts together to build a large application in a time-constrained manner.

Throughout the chapters we will design, architect and develop a complete stateful application serving an API via HTTP, accessing a database and dealing with cached data, using the best practices and best functional libraries available in the Cats ecosystem such as Cats Effect, Fs2, Http4s, Skunk, Refined & others.

You will also learn about common design patterns such as managing state, error handling and anti-patterns, all accompanied by clear examples. Furthermore, in the Bonus Chapter, we will dive into some advanced concepts such as MTL and Optics, and will explore Fs2 streams with a few interesting examples.

The book is supplemented by two Scala projects:
