It is an extensible framework that is data-driven and implemented using protocols (https://clojure.org/reference/protocols) to reduce the coupling between its components. It favors data over functions and functions over macros. It allows for the creation of data-driven routes and handlers that can apply a different behavior at runtime based on incoming requests. This makes it possible to create highly flexible and dynamic services that are well suited for microservice-based applications. It also supports the building of scalable asynchronous services using server-sent events (SSE) and WebSockets:
