Optimize your work with nested immutable data structures using Optics.

kotlin

Looking into immutable data with Optics 🔎

Immutability is a concept supported in Kotlin that we usually implement using data classes and read only properties. Working with complex nested immutable structures can be a bit unfriendly with this language, given how nested calls to the copy constructor lead to hardly understandable codebases. In this talk, we will learn about optics, and how we can use and compose them to create highly reusable paths to update our nested data structures.

  • Intro into Optics (Lens, Prism, Optional)
  • Composing Optics
  • Seperating path vs logic (includes DSL)
  • Outro: more optics (Traversal / Fold)

A Q&A session will immediately follow this talk.
