Ring-Serve provides a convenient way of starting a web server for a Ring handler.

The serve macro:

• Is safe to run multiple times.
• Finds a free port if you do not specify one.
• Opens up a web browser to view your handler, or if you don't want this, call the serve-headless macro instead.
• Automatically takes into account any changes made to your handler.
• Wraps your handler in the wrap-stacktrace middleware.
• Ensures that the swank.core/break function works correctly inside your handler.

user> (defn handler [request]
        {:status 200
         :headers {"Content-Type" "text/plain"}
         :body "Hello World"})
#'user/handler
user> (use 'ring.util.serve)
nil
user> (serve handler)
Started web server on port 3000
nil
user> (stop-server)
Stopped web server
nil
