auth0-demo

Simple Clojure authentication example for Auth0, using Buddy.

Prerequisites

You will need Leiningen 2.0.0 or above installed.

You need to create an account on Auth0, and a client to use for authentication. The client should have Google authentication enabled.

Running

To build a standalone jar, run:

lein uberjar

Run it like this:

$ java [-Doption=value ...] -jar auth0-demo.standalone.jar
$ [OPTION=value ...] java -jar auth0-demo.standalone.jar

or using Leiningen (requires a profiles.clj with options, more about that below):

$ lein ring server

or without opening a browser window:

$ lein ring server-headless

Options

Some options are only possible to set using environment variables or Java system variables. The options in the table below are shown as Clojure keywords, eg :auth-domain. Those are used in the profiles.clj file, which is useful when running the system using Leiningen, running a REPL using Leiningen, or running tests using Leiningen. The file should look like this:

{:dev-overrides
  {:env {:auth-domain "cljdemo.eu.auth0.com"
         :auth-client-id "someid"
         :auth-client-secret "thesecretkey"}}
 ...}

The :auth-return-to-uri and :auth-callback-uri keys are optional, but can be specified like this:

{:dev-overrides
  {:env {:auth-domain "cljdemo.eu.auth0.com"
         :auth-client-id "someid"
         :auth-client-secret "thesecretkey"
         :auth-callback-uri "http://localhost:3000/callback"
         :auth-return-to-uri "http://localhost:3000/login"}}}

If Java system variables are used, remove the colon and replace dashes with dots, as in -Dauth.domain:

$ java -Dauth.domain=cljdemo.eu.auth0.com \
-Dauth.client.id=someid \
-Dauth.client.secret='thesecretkey' \
-jar auth0demo.standalone.jar

If environment variables are used, remove the colon, replace dashes with underscore, and change to uppercase, as in AUTH_DOMAIN:

$ AUTH_DOMAIN=cljdemo.eu.auth0.com \
AUTH_CLIENT_ID=someid \
AUTH_CLIENT_SECRET='thesecretkey' ... \
java -jar auth0-demo.standalone.jar

The web server port can also be changed:

$ PORT=3333 ... java -jar auth0-demo.standalone.jar
$ java -Dport=4444 ... -jar auth0-demo.standalone.jar

keyword	env var	default	required	description
:auth-domain	AUTH_DOMAIN		yes	Auth0 client domain, for example: cljdemo.eu.auth0.com
:auth-client-id	AUTH_CLIENT_ID		yes	Auth0 client id.
:auth-client-secret	AUTH_CLIENT_SECRET		yes	Auth0 client secret.
:auth-callback-uri	AUTH_CALLBACK_URI	http://localhost:<PORT>/callback	no	The URI which will be called after successful authentication.
:auth-return-to-uri	AUTH_RETURN_TO_URI	http://localhost:<PORT>/login	no	The URI to redirect to after logout.
:port	PORT	3000	no	Web server port. Note that the 'Allowed Callback URLs' and 'Allowed Logout URLs' on Auth0 need to include this port.

The reason the profiles should be named *-overrides is that in order to merge profiles correctly, they are defined like this in project.clj:

  :profiles {:dev         [:dev-common :dev-overrides]
             :dev-common  {:dependencies [[javax.servlet/servlet-api "2.5"]
                                          [ring/ring-mock "0.3.0"]]}}
