Practical Scala DSLs: Real-World Applications Using Domain Specific Languages

Build domain specific languages (DSLs) using Java’s most popular functional programming language: Scala. This book introduces the basics of Scala and DSLs using a series of practical examples. In Practical Scala DSLs, you’ll learn to create pragmatic and complete code examples that explain the actual use of DSLs with Scala: a web API and microservices; a custom language; a mobile app; a Forex system; a game; and cloud applications.

At the end of this unique book, you’ll be able to describe the differences between external and internal DSLs; understand when and how to apply DSLs; create DSLs using Scala; and even create a DSL using another programming language.
