Two presentations:

Kevin Webber: Akka Streams

Pub/sub, dynamic push/pull, non-blocking, non-dropping; these are some of the concepts we'll cover, but more importantly we'll discuss how to leverage streams in a real-world application. Are streams just collections? How do I incorporate streams into a real world architecture? What are the benefits? These are a few of the questions we’ll answer during this talk

Mark Waks: End-to-End Scala: a Case Study in Integrating Akka, Play, Scala, and Scala.js

Querki is an online database/website app written entirely in Scala. In this session, we will go spelunking into its code ( https://github.com/jducoeur/Querki ), discussing the front-end Scala.js framework and the back-end Akka framework, looking a bit at how a Scala.js Single-Page Application works and how to use Cluster Sharding to easily build a scalable system in the back. The main focus will be on how the API works, using a combination of Play and Autowire to not just write a completely native-Scala API, but even propagate strongly-typed Exceptions from the server to the client. A particular goal is exploring how we can connect a front-end UI component with the correct back-end user session automatically, with nearly zero boilerplate.
