How is Keechma Different
summary
Keechma is a Reagent-based frontend framework that powers about 40 production apps and treats the URL as the primary source of truth. It uses a route-centric model where route changes start and stop stateful controllers with a strict controller lifecycle, communicating via core.async channels so sockets and UI commands map to single controller handlers. It adds promise-based pipelines (promesa) for ordered side effects and a centralized data loader to manage dependent API loading and cache invalidation; apps start/stop predictable and avoid global state.
