Shapeless

Shapeless is a powerful generic programming library for Scala, enabling compile-time abstraction and manipulation of types. It provides features such as HLists (heterogenous lists), generic derivation of type class instances, dependent types, and polymorphic functions—allowing developers to write boilerplate-free, type-safe code.

Features

Supports HLists and Coproducts for heterogeneous data structures
Generic derivation of type class instances across case classes
Polymorphic functions and function lifting across varying types
Compile-time tooling for transformations between tuples, case classes, and sealed traits
Powerful type-level programming without macros
Useful for serialization, validation, auto-derivation, and boilerplate reduction
