$ mojolicious generate lite_app [exist] /Users/marcus [write] /Users/marcus/foosball [chmod] foosball 744 That was easy. Now let’s check out the contents of the ﬁle

Lite app #!/usr/bin/env perl use Mojolicious::Lite; get '/' => 'index'; get '/:groovy' => sub { my $self = shift; $self->render_text( $self->param('groovy')); }; shagadelic;

Lite app (enterprise edition) #!/usr/bin/env perl use Mojolicious::Lite; get '/' => 'index'; get '/:synergy' => sub { my $self = shift; $self->render_text( $self->param('synergy')); }; app->start;

View __DATA__ @@ index.html.ep % layout 'funky'; Yea baby! @@ layouts/funky.html.ep <!doctype html><html> <head><title>Funky!</title></head> <body><%== content %></body> </html>

Let’s fire her up: $ ./foosball usage: foosball COMMAND [OPTIONS] These commands are currently available: generate Generate files and directories from templates. routes Show available routes. cgi Start application with CGI backend. daemon Start application with HTTP 1.1 backend. daemon_prefork Start application with preforking HTTP 1.1 backend. fastcgi Start application with FastCGI backend. get Get file from URL. psgi Start application with PSGI backend. test Run unit tests. version Show versions of installed modules. See 'foosball help COMMAND' for more information on a specific command. $ ./foosball daemon Server available at http://Command-Central.local:3000.
