Hi all...
I'm an italian mathematician/developer and I'm working on a small tutorial
on ClojureScript/Clojure.
I'd like to give an insight into client server comunication via the
shoreleave library and lein ring.
Actually, I'd like to validate a email/password with this simple cljs
function attached to a login form:
"Client Side"
(ns CLJS-NS
(:require [shoreleave.remotes.http-rpc :as rpc]))
(defn validate-usr
[eml pswd]
(let [regex-mail
#"^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$"]
(if (not (re-matches regex-mail eml))
(do (js/alert "Please, insert a valid email address.")
false)
(rpc/remote-callback :sign-in [eml pswd] #(sign-action %)))))
Meanwhile I defined in a clj ns the following function:
"Server Side"
(ns CLJ-NS
(:require [cemerick.shoreleave.rpc :refer (defremote)]))
(defremote ^{:remote-name ::sign-in} sign-in
[eml pswd]
(let [signing-usr {:email eml :password pswd}]
(contains? database signing-usr)))
The problem now is how can I make the client see the remote function, as
the ring server throws a 404 error once i trigger the "login" event.
