Mojo(3) Web development toolkit


package MyApp;
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
$tx->res->body("$method request for $path!");
# Resume transaction


A powerful web development toolkit, with all the basic tools and helpers needed to write simple web applications and higher level web frameworks, such as Mojolicious. Some of the most commonly used tools are Mojo::UserAgent, Mojo::DOM, Mojo::JSON, Mojo::Server::Daemon, Mojo::Server::Prefork, Mojo::IOLoop and Mojo::Template.

See Mojolicious::Guides for more!


Mojo implements the following attributes.


  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');


  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');


  my $ua = $app->ua;
  $app   = $app->ua(Mojo::UserAgent->new);

A full featured HTTP user agent for use in your applications, defaults to a Mojo::UserAgent object.

  # Perform blocking request
  say $app->ua->get('')->res->body;


Mojo inherits all methods from Mojo::Base and implements the following new ones.


  my $tx = $app->build_tx;

Transaction builder, defaults to building a Mojo::Transaction::HTTP object.


  my $hash = $app->config;
  my $foo  = $app->config('foo');
  $app     = $app->config({foo => 'bar', baz => 23});
  $app     = $app->config(foo => 'bar', baz => 23);

Application configuration.

  # Remove value
  my $foo = delete $app->config->{foo};
  # Assign multiple values at once
  $app->config(foo => 'test', bar => 23);



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) = @_;
