.SH DESCRIPTION
.IX Header "DESCRIPTION"
This is \fIyet another\fR approach to refresh modules in \f(CW%INC\fR 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 \fIcooldown\fR seconds which defaults to 10,
call Module::Refresh to reload all Perl modules in \f(CW%INC\fR if the
files have been modified.
.PP
Note that this only reloads modules and not other files such as
templates.
.PP
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 \f(CW\*(C`make_immutable\*(C'\fR, take a look at plackup's default \-r option
or Plack::Loader::Shotgun instead.
