In this episode, we explore the Functional Core, Imperative Shell (FC/IS) architecture pattern popularized by Gary Bernhardt. This powerful approach separates pure business logic from side effects, resulting in code that's more testable, maintainable, and reasoning-friendly.
We'll discuss how FC/IS differs from traditional layered architectures by treating effects as data, enabling an impressive 85% of code to exist as pure functions. Using the analogy of a presidential cabinet, we explain how the functional core makes decisions while the imperative shell handles execution.
The episode covers practical implementation strategies, the crucial role of Datomic in solving the "all relevant facts" problem, and real-world benefits including enhanced REPL-driven development, simplified error reproduction, and improved system observability.
