NAME¶
Plack::Loader::Shotgun - forking implementation of plackup
SYNOPSIS¶
plackup -L Shotgun
DESCRIPTION¶
Shotgun loader delays the compilation and execution of your application until
the runtime. When a new request comes in, this forks a new child, compiles
your code and runs the application.
This should be an ultimate alternative solution when reloading with
Plack::Middleware::Refresh doesn't work, or plackup's default "-r"
filesystem watcher causes problems. I can imagine this is useful for
applications which expects their application is only evaluated once (like
in-file templates) or on operating systems with broken fork implementation,
etc.
This is much like good old CGI's fork and run but you don't need a web server,
and there's a benefit of preloading modules that are not likely to change. For
instance if you develop a web application using Moose and DBIx::Class,
plackup -MMoose -MDBIx::Class -L Shotgun yourapp.psgi
would preload those modules and only re-evaluates your code in every request.
