Basic Usage

Since reel-rack is a Rack-based web server, we need to make a config.ru (a.k.a. "rackup") file for it to serve. We'll use the following one:

# config.ru
run Proc.new {|env| [200, {"Content-Type" => "text/html"}, "Hello Rack!"]}

Now we need to install the reel-rack gem to serve this "application":

$ gem install reel-rack
Fetching: timers-1.1.0.gem (100%)
Successfully installed timers-1.1.0
Fetching: celluloid-0.15.1.gem (100%)

Fetching: nio4r-0.5.0.gem (100%)

Fetching: rack-1.5.2.gem (100%)
Successfully installed rack-1.5.2
Fetching: reel-rack-0.0.2.gem (100%)
Successfully installed reel-rack-0.0.2

Once the reel-rack has been installed, we can start Reel by running the associated command:

$ reel-rack config.ru
I, [2013-09-14T23:40:14.556975 #7674]  INFO -- : A Reel good HTTP server! (Codename "Garbo")
I, [2013-09-14T23:40:14.557065 #7674]  INFO -- : Listening on http://0.0.0.0:3000

We now have our "Hello Rack!" application listening on port 3000. We can confirm it's running using a tool like curl:

$ curl http://0.0.0.0:3000
Hello Rack!
