Constructor Details
#initialize(options = nil) ⇒ Server
Options may include:
-
:app
a rack application to run (overrides :config and :builder)
-
:builder
a string to evaluate a Rack::Builder from
-
:config
a rackup configuration file path to load (.ru)
-
:environment
this selects the middleware that will be wrapped around your application. Default options available are: - development: CommonLogger, ShowExceptions, and Lint - deployment: CommonLogger - none: no extra middleware note: when the server is a cgi server, CommonLogger is not included.
-
:server
choose a specific Rackup::Handler, e.g. cgi, fcgi, webrick
-
:daemonize
if truthy, the server will daemonize itself (fork, detach, etc) if :noclose, the server will not close STDOUT/STDERR
-
:pid
path to write a pid file after daemonize
-
:Host
the host address to bind to (used by supporting Rackup::Handler)
-
:Port
the port to bind to (used by supporting Rackup::Handler)
-
:AccessLog
webrick access log options (or supporting Rackup::Handler)
-
:debug
turn on debug output ($DEBUG = true)
-
:warn
turn on warnings ($-w = true)
-
:include
add given paths to $LOAD_PATH
-
:require
require the given libraries
Additional options for profiling app initialization include:
-
:heapfile
location for ObjectSpace.dump_all to write the output to
-
:profile_file
location for CPU/Memory (StackProf) profile output (defaults to a tempfile)
-
:profile_mode
StackProf profile mode (cpu|wall|object)

.start(options = nil) ⇒ Object
Start a new rack server (like running rackup). This will parse ARGV and provide standard ARGV rackup options, defaulting to load ‘config.ru’.
Providing an options hash will prevent ARGV parsing and will not include any default options.
This method can be used to very easily launch a CGI application, for example:
Rack::Server.start(
:app => lambda do |e|
[200, {'content-type' => 'text/html'}, ['hello world']]
end,
:server => 'cgi'
)
Further options available here are documented on Rack::Server#initialize
