Castra

Castra allows calling server functions directly from the client using Clojure expressions, abstracting HTTP details as shown in examples like `(update-record 123 {:x 1 :y 2})`, reducing boilerplate.

Integrates with Javelin cells to automatically manage loading, error, and success states for remote calls, demonstrated in client code with `record`, `error`, and `loading` cells.

Easily plugs into Ring-based Clojure servers via `wrap-castra`, requiring minimal configuration for server-side setup without additional HTTP handling.

Embraces CQRS and unidirectional patterns, promoting scalable architecture by separating commands and queries, as highlighted in the philosophy and Hoplon examples.
