Serve index.html at / by default in Compojure

Question

I have a static file called index.html that I\'d like to serve when someone requests /. Usually web servers do this by default, but Compojure doesn

This would be a pretty simple Ring middleware:

(defn wrap-dir-index [handler]
  (fn [req]
    (handler
     (update-in req [:uri]
                #(if (= "/" %) "/index.html" %)))))

Just wrap your routes with this function, and requests for / get transformed into requests for /index.html before the rest of your code sees them.

(def app (-> (routes (your-dynamic-routes)
                     (resources "/"))
             (...other wrappers...)
             (wrap-dir-index)))
