=head1 NAME
Plack::Middleware::Refresh - Refresh all modules in %INC
=head1 SYNOPSIS
enable "Refresh", cooldown => 3;
$app;
=head1 DESCRIPTION
This is I<yet another> approach to refresh modules in C<%INC> during
the development cycle, without the need to have a forking process to
watch for filesystem updates. This middleware, in a request time,
compares the last refresh time and the current time and if the
difference is bigger than I<cooldown> seconds which defaults to 10,
call L<Module::Refresh> to reload all Perl modules in C<%INC> if the
files have been modified.
Note that this only reloads modules and not other files such as
templates.
This middleware is quite similar to what Rack::Reoader does. If you
have issues with this reloading technique, for instance when you have
in-file templates that needs to be recompiled, or Moose classes that
has C<make_immutable>, take a look at L<plackup>'s default -r option
or L<Plack::Loader::Shotgun> instead.
