No, you can have as many endpoint components as you want.
Duct has a handler component that looks for endpoint components in its
dependencies, and combines their routes together using
compojure.core/routes.
One of the ideas in Duct is to group routes together by purpose, to achieve
the modularity of micro-service architecture without the overhead.
For example, let's say you have endpoints foo, bar and baz. Then your
system builder in Duct would look like:
(defn new-system [config]
(let [config (meta-merge base-config config)]
(-> (component/system-map
:http (jetty-server (:http config))
:app (handler-component (:app config))
:foo (endpoint-component foo-endpoint)
:bar (endpoint-component bar-endpoint)
:baz (endpoint-component baz-endpoint))
(component/system-using
{:http [:app]
:app [:foo :bar :baz]}))))
