As Kotlin programming language is getting more popular, the creators of the libraries are starting to provide Kotlin API for their frameworks. The number of libraries that provide a nice little DSL grows constantly. The session introduces you to some of those libraries and explains, how Kotlin makes creating the DSL so simple. Lambdas, extension methods, lambdas with the receiver, and other syntactic sugar make it easy to implement DSL in Kotlin. In a live coding demo, we will create a simple DSL for the existing Java classes that could be used from a Kotlin code.
