=head1 NAME
Mojo - The Box!
=head1 SYNOPSIS
use base 'Mojo';
# All the complexities of CGI, FastCGI, PSGI, HTTP and WebSocket 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->headers->content_type('text/plain');
$tx->res->body("$method request for $path!");
}
=head1 DESCRIPTION
Mojo provides a flexible runtime environment for Perl web frameworks.
It provides all the basic tools and helpers needed to write simple web
applications and higher level web frameworks such as L<Mojolicious>.
See L<Mojolicious> for more!
=head1 ATTRIBUTES
L<Mojo> implements the following attributes.
=head2 C<build_tx_cb>
my $cb = $mojo->build_tx_cb;
$mojo = $mojo->build_tx_cb(sub { ... });
The transaction builder callback, by default it builds a
L<Mojo::Transaction::HTTP> object.
=head2 C<client>
my $client = $mojo->client;
$mojo = $mojo->client(Mojo::Client->new);
A full featured HTTP 1.1 client for use in your applications, by default a
L<Mojo::Client> object.
=head2 C<home>
my $home = $mojo->home;
$mojo = $mojo->home(Mojo::Home->new);
The home directory of your application, by default a L<Mojo::Home> object
which stringifies to the actual path.
=head2 C<log>
my $log = $mojo->log;
$mojo = $mojo->log(Mojo::Log->new);
The logging layer of your application, by default a L<Mojo::Log> object.
=head2 C<websocket_handshake_cb>
my $cb = $mojo->websocket_handshake_cb;
$mojo = $mojo->websocket_handshake_cb(sub { ... });
The websocket handshake callback, by default it builds a
L<Mojo::Transaction::WebSocket> object and handles the response for the
handshake request.
=head1 METHODS
L<Mojo> inherits all methods from L<Mojo::Base> and implements the following
new ones.
=head2 C<new>
my $mojo = Mojo->new;
Construct a new L<Mojo> application.
Will automatically detect your home directory and set up logging to
C<log/mojo.log> if there's a log directory.
=head2 C<handler>
$tx = $mojo->handler($tx);
The handler is the main entry point to your application or framework and
will be called for each new transaction.
sub handler {
my ($self, $tx) = @_;
}
=head2 C<start>
Mojo->start;
Mojo->start('daemon');
Start the L<Mojo::Commands> command line interface for your application.
=head1 SEE ALSO
L<Mojolicious>, L<Mojolicious::Guides>, L<http://mojolicious.org>.
