Lessons Learned using PureScript to build Mobile App Dev Framework
summary
Describes using PureScript (a Haskell-like language that compiles to JavaScript) to build a mobile app development framework for transactional apps modeled as conversational flows. Presents an approach that represents UI components and business flows as pure functions and a free-monadic UX DSL with continuation-passing style semantics to unify frontend and backend flows, enabling composable, reusable blocks and easier onboarding of non-expert engineers.
