packages deploy complex applications made of data files and executables. They install the application, sometimes with help from a special program.

tar balls on tape are just archives, they do not know how to deploy an app. If you want to install an app from tape, you have to know everything about how to do it.

NAME
Mojo - Duct tape for the HTML5 web! SYNOPSIS
use Mojo::Base 'Mojo'; # All the complexities of CGI, PSGI, HTTP and WebSockets get reduced to a # single method call! sub handler { my ($self, $tx) = @_; # Request my $method = $tx->req->method; my $path = $tx->req->url->path; # Response $tx->res->code(200); $tx->res->headers->content_type('text/plain'); $tx->res->body("$method request for $path!"); # Resume transaction $tx->resume; } DESCRIPTION
Mojo provides a flexible runtime environment for Perl real-time web frameworks. It provides all the basic tools and helpers needed to write simple web applications and higher level web frameworks such as Mojolicious. See Mojolicious for more! ATTRIBUTES
Mojo implements the following attributes. "home" my $home = $app->home; $app = $app->home(Mojo::Home->new); The home directory of your application, defaults to a Mojo::Home object which stringifies to the actual path. # Generate portable path relative to home directory my $path = $app->home->rel_file('data/important.txt'); "log" my $log = $app->log; $app = $app->log(Mojo::Log->new); The logging layer of your application, defaults to a Mojo::Log object. # Log debug message $app->log->debug('It works!'); "ua" my $ua = $app->ua; $app = $app->ua(Mojo::UserAgent->new); A full featured HTTP 1.1 user agent for use in your applications, defaults to a Mojo::UserAgent object. Note that this user agent should not be used in plugins, since non-blocking requests that are already in progress will interfere with new blocking ones. # Perform blocking request my $body = $app->ua->get('mojolicio.us')->res->body; METHODS
Mojo inherits all methods from Mojo::Base and implements the following new ones. "new" my $app = Mojo->new; Construct a new Mojo application. Will automatically detect your home directory and set up logging to "log/mojo.log" if there's a "log" directory. "build_tx" my $tx = $app->build_tx; Transaction builder, defaults to building a Mojo::Transaction::HTTP object. "config" my $config = $app->config; my $foo = $app->config('foo'); $app = $app->config({foo => 'bar'}); $app = $app->config(foo => 'bar'); Application configuration. # Manipulate configuration $app->config->{foo} = 'bar'; my $foo = $app->config->{foo}; delete $app->config->{foo}; "handler" $app->handler($tx); The handler is the main entry point to your application or framework and will be called for each new transaction, which will usually be a Mojo::Transaction::HTTP or Mojo::Transaction::WebSocket object. Meant to be overloaded in a subclass. sub handler { my ($self, $tx) = @_; ... } SEE ALSO
