SME Web Application Framework provides a Web application framework for small and medium-sized organizations.

SMEWebApp is a framework for constructing Web applications for SMEs (small and medium-sized enterprises, companies, institutions, and organizations). It is built on phpWebApp, and it is higher-level and more specific than phpWebApp.

It has some components that can be reused in any application (perhaps with small modifications), like hierarchical menus, user authentication, and user administration.

The aim of the project is to make Web application construction for SMEs easier than using VB.

CGI::Application is a framework for building reusable web-applications.

SYNOPSIS

# In "WebApp.pm"...
package WebApp;
use base CGI::Application;

# ( setup() can even be skipped for common cases. See docs below. )
sub setup {
my $self = shift;
$self->start_mode(mode1);
$self->mode_param(rm);
$self->run_modes(
mode1 => do_stuff,
mode2 => do_more_stuff,
mode3 => do_something_else
);
}
sub do_stuff { ... }
sub do_more_stuff { ... }
sub do_something_else { ... }
1;


### In "webapp.cgi"...
use WebApp;
my $webapp = WebApp->new();
$webapp->run();

CGI::Application is intended to make it easier to create sophisticated, high-performance, reusable web-based applications. This module implements a methodology which, if followed, will make your web software easier to design, easier to document, easier to write, and easier to evolve.

CGI::Application judiciously avoids employing technologies and techniques which would bind a developer to any one set of tools, operating system or web server.

REST::Application is a framework for building RESTful web-applications.

SYNOPSIS

# MyRESTApp L instance / mod_perl handler
package MyRESTApp;
use Apache;
use Apache::Constants qw(:common);

sub handler {
__PACKAGE__->new(request => $r)->run();
return OK;
}

sub getMatchText { return Apache->uri }

sub setup {
my $self = shift;
$self->resourceHooks(
qr{/rest/parts/(d+)} => get_part,
# ... other handlers here ...
);
}

sub get_part {
my ($self, $part_num) = @_;
# Business logic to retrieve part num
}

# Apache conf
< Location /rest >
perl-script .cgi
PerlHandler MyRESTApp
< /Location >

This module acts as a base class for applications which implement a RESTful interface. When an HTTP request is received some dispatching logic in REST::Application is invoked, calling different handlers based on what the kind of HTTP request it was (i.e. GET, PUT, etc) and what resource it was trying to access. This module wont ensure that your API is RESTful but hopefully it will aid in developing a REST API.

OpenPlugin::Application is a subclass of CGI::Application, meant to help you create reusable web applications.

SYNOPSIS

# Example from OpenThoughts Demo.pm

package Demo;
use base "OpenPlugin::Application";
sub setup {
my $self = shift;
$self->run_modes(
mode1 => init_demo,
mode2 => get_os_list,
mode3 => get_os_info,
);
$self->start_mode( mode1 );
$self->mode_param(run_mode);
}
sub init_demo { ... }
sub get_os_list { ... }
sub get_os_info { ... }
1;

# Example from OpenThoughts demo.pl

#!/usr/bin/perl -wT
use strict;
my $r = shift;
my $demo = Demo->new( PARAMS => {
config => { src => "/path/to/OpenPlugin.conf" },
request => { apache => $r },
});

$demo->run();

OpenPlugin::Application is built on Jesse Erlbaums popular CGI::Application module. OpenPlugin::Application is simply a subclass of CGI::Application. Jesse says the following about CGI::Application:

"CGI::Application is intended to make it easier to create sophisticated, reusable web-based applications. This module implements a methodology which, if followed, will make your web software easier to design, easier to document, easier to write, and easier to evolve."

How does it do this? Jesse goes on to say:

"The guiding philosophy behind CGI::Application is that a web-based application can be organized into a specific set of "Run-Modes." Each Run-Mode is roughly analogous to a single screen (a form, some output, etc.). All the Run-Modes are managed by a single "Application Module" which is a Perl module. In your web servers document space there is an "Instance Script" which is called by the web server"

The biggest difference between CGI::Application and OpenPlugin::Application is that query object they both use; one is designed to use CGI.pm, the other OpenPlugin. Generally speaking, everything in the still applies. Any differences will be noted in this document.
It is not necessary to use OpenPlugin::Application in order to build web applications using OpenPlugin. This plugin is meant to be for your convenience -- to help you structure your web applications in a manner which makes sense, and is reusable.

Bulk Meter Flow and Operations provides a Web-based application to manage water meter readings.

IssueTrackerProduct is an issue/bug tracker Web application that uses the Zope Web application server.

IssueTrackerProduct is very easy to use, and fancy features are switched off by default.
