In Compojure, if you want to display a static file from resource/public,
you can either redirect to that file or serve it as a resource response using
functions provided by ring-core library via ring.util.response.
Let’s consider the following application:
(ns example.core
(:use ring.util.response)
(:require [compojure.handler :as handler]
[compojure.route :as route]
[compojure.core :refer [GET POST defroutes]]))
(defroutes app-routes
(GET "/" [] ...)
(route/resources "/")
(route/not-found "Page not found"))
(def app
(handler/api app-routes))
In the case of the redirect, you should replace … by the following line
(redirect “index.html”)
With this approach index.html will be part of the URL. If you prefer not to
display index.html as a part of the URL while serving it to the user, you
should use resource-response function i.e.
(resource-response "index.html" {:root "public"})
This function serves files found on the classpath - it means it will also work
for the uberjar which is not true for file-resource function.
It's public as opposed to resources/public, because resources is one of
the top-level directories included in the uberjar.
