In this live coding session in Scala, Kfir Bloch (Head of Backend Engineering at Wix) will showcase how to build a full-blown feature in Scala, while maintaining the principles of TDD and Clean Code. We'll start with some simple scaffolding and build the feature in its entirety: defining the user-facing API, writing tests outside-in with all of the required building blocks (collaborators and matchers) and development-refactoring cycles, and end up with a clean codebase.
