       plackup - Run PSGI application with Plack handlers


         # read your app from app.psgi file

         # choose .psgi file from ARGV[0] (or with -a option)
         plackup hello.psgi

         # switch server implementation with --server (or -s)
         plackup --server HTTP::Server::Simple --port 9090 --host test.psgi

         # use UNIX socket to run FCGI daemon
         plackup -s FCGI --listen /tmp/fcgi.sock myapp.psgi

         # launch FCGI external server on port 9090
         plackup -s FCGI --port 9090


       plackup is a command line utility to run PSGI applications from the command line.

       plackup automatically figures out the environment it is run in, and runs your application
       in that environment. FastCGI, CGI, AnyEvent and others can all be detected. See
       Plack::Loader for the authoritative list.

       "plackup" assumes you have an "app.psgi" script in your current directory.  The last
       statement of "app.psgi" should be a code reference that is a PSGI application:

         use MyApp;
         my $application = MyApp->new;
         my $app = sub { $application->run_psgi(@_) };


             plackup --host --port 9090 /path/to/app.psgi

           The first non-option argument is used as a ".psgi" file path. You can also set this
           path with "-a" or "--app". If omitted, the default file path is "app.psgi" in the
           current directory.


       -a, --app
           Specifies the full path to a ".psgi" script. You may alternately provide this path as
           the first argument to "plackup".

       -e  Evaluates the given perl code as a PSGI app, much like perl's "-e" option:

             plackup -e 'sub { my $env = shift; return [ ... ] }'

           It is also handy when you want to run a custom application like Plack::App::*.

             plackup -MPlack::App::File -e 'Plack::App::File->new(...)->to_app'

           You can also specify "-e" option with ".psgi" file path to wrap the application with
           middleware configuration from the command line. You can also use Plack::Builder DSL
           syntax inside "-e" code. For example:

             plackup -e 'enable "Auth::Basic", authenticator => ...;' myapp.psgi

           is equivalent to the PSGI application:

             use Plack::Builder;
             use Plack::Util;

             builder {
                 enable "Auth::Basic", authenticator => ...;

           Note that when you use "-e" option to enable middleware, plackup doesn't assume the
           implicit "app.psgi" path. You must either pass the path to your ".psgi" file in the
           command line arguments or load the application inside "-e" after the "enable".

             plackup                                # Runs app.psgi
             plackup -e 'enable "Foo"'              # Doesn't work!
             plackup -e 'enable "Foo"' app.psgi     # Works
             plackup -e 'enable "Foo"; sub { ... }' # Works

       -o, --host
           Binds to a TCP interface. Defaults to undef, which lets most server backends bind to
           the any (*) interface. This option is only valid for servers which support TCP

       -p, --port
           Binds to a TCP port. Defaults to 5000. This option is only valid for servers which
           support TCP sockets.

       -s, --server, the "PLACK_SERVER" environment variable
           Selects a specific server implementation to run on. When provided, the "-s" or
           "--server" flag will be preferred over the environment variable.

           If no option is given, plackup will try to detect the best server implementation based
           on the environment variables as well as modules loaded by your application in %INC.
           See Plack::Loader for details.

       -S, --socket
           Listens on a UNIX domain socket path. Defaults to undef. This option is only valid for
           servers which support UNIX sockets.

       -l, --listen
           Listens on one or more addresses, whether "HOST:PORT", ":PORT", or "PATH" (without
           colons). You may use this option multiple times to listen on multiple addresses, but
           the server will decide whether it supports multiple interfaces.

       -D, --daemonize
           Makes the process run in the background. It's up to the backend server/handler
           implementation whether this option is respected or not.

       -I  Specifies Perl library include paths, like "perl"'s -I option. You may add multiple
           paths by using this option multiple times.

       -M  Loads the named modules before loading the app's code. You may load multiple modules
           by using this option multiple times.

           In combination with "-r" or "-R" may not have the desired restart effect when the
           loaded module is changed in the development directory. To avoid this problem you need
           to load the module with the app code using "-e".

       -E, --env, the "PLACK_ENV" environment variable.
           Specifies the environment option. Setting this value with "-E" or "--env" also writes
           to the "PLACK_ENV" environment variable. This allows applications or frameworks to
           tell which environment setting the application is running on.

             # These two are the same
             plackup -E deployment
             env PLACK_ENV=deployment plackup

           Common values are "development", "deployment", and "test". The default value is
           "development", which causes "plackup" to load the middleware components: AccessLog,
           StackTrace, and Lint unless "--no-default-middleware" is set.

           This prevents loading the default middleware stack even when Plack environment (i.e.
           "-E" or "PLACK_ENV") is set to "development".

       -r, --reload
           Makes plackup restart the server whenever a file in your development directory
           changes. This option by default watches the "lib" directory and the base directory
           where .psgi file is located. Use "-R" to watch other directories.

           Reloading will delay the compilation of your application. Automatic server detection
           (see "-s" above) may not behave as you expect, if plackup needs to scan your
           application for the modules it uses. Avoid problems by specifying "-s" explicitly when
           using "-r" or "-R".

           To avoid problems with changes to preloaded modules see documentation for "-M".

       -R, --Reload
           Makes plackup restart the server whenever a file in any of the given directories
           changes. "-R" and "--Reload" take a comma-separated list of paths:

             plackup -R /path/to/project/lib,/path/to/project/templates

           To avoid problems with changes to preloaded modules see documentation for "-M".

       -L, --loader
           Specifies the server loading subclass that implements how to run the server.
           Available options are Plack::Loader (default), Restarter (automatically set when "-r"
           or "-R" is used), Delayed, and Shotgun.

           See Plack::Loader::Delayed and Plack::Loader::Shotgun for more details.

           Specifies the pathname of a file where the access log should be written.  By default,
           in the development environment access logs will go to STDERR.

           Specify the root path of your app ("SCRIPT_NAME" in PSGI env) to run. The following
           two commands are roughly the same.

             plackup --path /foo app.psgi
             plackup -e 'mount "/foo" => Plack::Util::load_psgi("app.psgi")'

       Other options that starts with "--" are passed through to the backend server.  See each
       Plack::Handler backend's documentation for more details on their available options.
