An Introduction to Lean and Functional Domain Modelling

Rich domain models, inspired by imperative objective-oriented approaches, dominate our industry. But lean domain models are a compelling alternative. By separating behaviour and state, lean models offer an effective way to represent units of behaviour. This session will explore how to represent a lean domain model using a functional programming paradigm. We’ll explore how types can be used as a natural way to represent business constraints alongside smart constructors and functional validation. How behaviour can be better composed, and how to keep domain behaviour isolated from application state.
