Overview of this book

<p>The Scala programming language has gained a lot of traction in the last couple of years because of its functional orientation and conciseness. The industry has a strong interest in using Scala in modern production systems, and as such, the Spray framework and Akka toolkit became a natural choice for back-end Scala developers building highly-scalable, reliable, reactive REST(ful) web services and APIs.</p> <p>This video course will be an exciting journey into the universe of the web development using the Scala programming language and frameworks. It is a starting point from which you'll learn the basics of building REST(ful) web services and APIs using the non-blocking and asynchronous programming models that lie in the heart of the Spray framework. You’ll start off by learning about the REST architecture. After that, you will switch gears to the Akka toolkit and Spray framework, building the sample book catalog application along the way.</p> <p>Once you've learned about the REST architectural style and Actor Model, the foundations that the Spray framework is built upon, you’ll shape out your own REST(ful) web services by providing simple route definitions. Further on, we'll delve into authentication, authorization, secure transport, documentation, test cases, and caching support. Finally, you will learn how to develop the Spray client API.</p> <h1>Style and Approach</h1> <p>This easy-to-follow video course takes a systematic approach by starting with the big problem, dividing it into sub-problems, and then solving each one of them as we progress.</p>

Authorization
Authentication helps a lot with answering the question about who is accessing the system. However, in most cases, this is not enough as the next challenge to solve is what the authenticated user is allowed to do? - Learn what the authorization is and its role in securing REST(ful) Web services and APIs - Discover the Spray Routing directives for performing authorization - Make a clear distinction between authentication and authorization, and discuss how they complement each other
