NAME

plackup - Run PSGI application with Plack servers

SYNOPSIS

# read your app from app.psgi file
plackup

# can be passed as an ARGV[0] (or with -a option)
plackup hello.psgi

# Switch server implementation with --server (or -s)
plackup --server HTTP::Server::Simple --port 9090 --host 127.0.0.1 test.psgi

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

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

DESCRIPTION

plackup is a command line utility to run PSGI application 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 authorative list.

plackup assumes you have an app.psgi script in your current directory, that would look like:

#!/usr/bin/perl
use MyApp;
my $app = MyApp->new;
my $handler = sub { $app->run_psgi(@_) };

The last statement of app.psgi should be a code reference that is a PSGI application.

ARGUMENTS

.psgi

plackup --host 127.0.0.1 --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 option. If omitted, the default file path is app.psgi in the current directory.

OPTIONS

-a, --app

--app option allows you to locate a .psgi script with a different name in a different path. This can also be set as a non-option argument. (See above)

-e

Evaluate the given perl code as a PSGI app, much like perl's -e option.

-o, --host

The interface a TCP based server daemon binds to. Defauts to undef, which lets most server backends bind the any (*) interface. This opeion doesn't mean anything if the server does not support TCP socket.

-p, --port

The port number a TCP based server daemon listens on. Defaults to 5000. This option doesn't mean anything if the server does not support TCP socket.

-s, --server

Select a specific implementation to run on using the PLACK_SERVER environment variable or use the -s or --server flag which will be prefered over the environment variable if present.

-S, --socket

UNIX domain socket path to listen on. Defaults to undef. This option doesn't mean anything if the server doesn't support UNIX sockets.

-l, --listen

Addresses to listen on. It could be "HOST:PORT", ":PORT" or "PATH" (without colons). It could be multiple but it depends on the server implementations whether multiple interfaces are supported.

-D, --daemonize

Makes the process go background. It's up to the backend server/handler implementation whether this option is respected or not.

-I

Specify perl library include path, like perl's -I option.

-M

Specify modules to load before loading the app code.

-E, --env

Specify the environment option (default is development). If it's set to development, following middleware is enabled by default: AccessLog, StackTrace.

-r, --reload

Make plackup to watch updates from your development directory and restarts the server whenever a file is updated. This option by default watches the lib directory and the base directory where .psgi file is located. Use -R if you want to watch other directories.

-R, --Reload

-R option allows you to specify the path to watch file updates separated by comma (,).

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

-L, --loader

Specify 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) and Shotgun.

Other options that starts with -- are passed through to the backend server. See each Plack::Server backend documentations to see which options are available.
