This is a an example Compojure-based web application that demonstrates a number of basic features of Ring and Compojure.

This example borrows heavily from James Reeves' Compojure-Example project.

The example is oriented towards Emacs/Slime/Swank users.

To play around with this example project, you will first need Leiningen installed.

Download the project dependencies with:

lein deps

Now you can start a development web server with:

lein swank

You should see something like this:

user=> Connection opened on local port  4005
#<ServerSocket ServerSocket[addr=localhost/127.0.0.1,port=0,localport=4005]>

Then, in emacs:

M-x slime-connect

Accept the default host and port, you should be connected to the running Clojure in your slime-repl window. Interact with the Clojure REPL as follows:

; SLIME 20100404
user> (use 'ring.util.serve)
nil
user> (use 'compojure.example.routes)
nil
user> (serve main-routes)
Started web server on port 3000

A web browser should get launched pointing to the web server running the app. If you prefer to launch the web browser yourself, call

(serve-headless main-routes)

instead.

I intend to extend this example with other typical features needed by a web application, with different feature sets contained in seperate branches of this project.

To Do:

Explain how to set an breakpoint in the app.

For some reason the second image in this app doesn't work in Safari. Use FireFox for now!
