Chapter 10. Scala Goodies

We have covered a number of technologies and toolkits in the previous chapters that, when combined together, offer a great opportunity to build modern and scalable-reactive web applications in Scala. Scala now celebrates 10 years of existence with an active community and large corporations supporting it, leading to a perpetual exploration of innovative ideas touching the language and the ecosystem.

We propose, in this last chapter, to touch upon a few areas where we have found some exciting ongoing projects or technologies and where we feel that Scala can provide elegant solutions to be both productive and fun. We will cover some of the following aspects:

  • NoSQL database access through MongoDB

  • Introducing DSLs and in particular, a glimpse at Parser Combinators

  • Scala.js—compiling Scala to JavaScript on the client side
