Creating a Compojure route

Let's do an example that will allow the awful sounding tech jargon to make sense. We will create an extremely basic route, which will simply print out the original request map to the screen. Let's perform the following steps:

    (defroutes home-routes
      (GET "/" [] (home-page))
      (GET "/about" [] (about-page))
      (ANY "/req" request (str request)))
  3. Start the Ring Server if it's not already started.
  4. Navigate to http://localhost:3000/req.

    Note
