ZIO is a new Scala library and zionomicon book helps you quickly create fault—tolerant and efficient parallel applications that are easy to understand and test, and that do not allow for resource leaks, deadlocks, or error loss. In one book that you can study in just 4 weeks, Zionomicon will give you the in-demand skills to succeed in one of the fastest growing libraries in the Scala ecosystem.

Why ZIO

ZIO is an innovative next—generation library for quickly creating modern applications that are highly competitive, efficient, asynchronous, and fully testable.

ZIO applications do not waste resources, are not blocked, and do not lose errors. Using the power of the Scala type system, ZIO applications are correct in design, with statically validated error behavior that requires less work and fewer tests to achieve a given level of application quality.

Themes

A detailed review of the aspects of ZIO, from the basics for getting started to concurrency and parallel data structures, resource processing, dependency injection, and software transactional memory. Includes streaming and testing processing. Each chapter is provided with clear learning objectives, exercises, and working examples so that you can make the most of it.
