NAME

Mojolicious - Real-time web framework

SYNOPSIS

  # Application
  package MyApp;
  use Mojo::Base 'Mojolicious';

  # Route
  sub startup {
    my $self = shift;
    $self->routes->get('/hello')->to('foo#hello');
  }

  # Controller
  package MyApp::Foo;
  use Mojo::Base 'Mojolicious::Controller';

  # Action
  sub hello {
    my $self = shift;
    $self->render(text => 'Hello World!');
  }

DESCRIPTION

Take a look at our excellent documentation in Mojolicious::Guides!

HOOKS

Mojolicious will emit the following hooks in the listed order.

after_build_tx

Emitted right after the transaction is built and before the HTTP request gets parsed.

  $app->hook(after_build_tx => sub {
    my ($tx, $app) = @_;
    ...
  });

This is a very powerful hook and should not be used lightly, it makes some rather advanced features such as upload progress bars possible. Note that this hook will not work for embedded applications. (Passed the transaction and application object)

before_dispatch

Emitted right before the static file server and router start their work.

  $app->hook(before_dispatch => sub {
    my $c = shift;
    ...
  });

Very useful for rewriting incoming requests and other preprocessing tasks. (Passed the default controller object)

after_static

Emitted after a static file response has been generated by the static file server.

  $app->hook(after_static => sub {
    my $c = shift;
    ...
  });

Mostly used for post-processing static file responses. (Passed the default controller object)

before_routes

Emitted after the static file server determined if a static file should be served and before the router starts its work.

  $app->hook(before_routes => sub {
    my $c = shift;
    ...
  });

Mostly used for custom dispatchers and collecting metrics. (Passed the default controller object)

around_action

Emitted right before an action gets invoked and wraps around it, so you have to manually forward to the next hook if you want to continue the chain. Default action dispatching is the last hook in the chain, yours will run before it.

  $app->hook(around_action => sub {
    my ($next, $c, $action, $last) = @_;
    ...
    return $next->();
  });

This is a very powerful hook and should not be used lightly, it allows you for example to pass additional arguments to actions or handle return values differently. (Passed a callback leading to the next hook, the current controller object, the action callback and a flag indicating if this action is an endpoint)

before_render

Emitted before content is generated by the renderer. Note that this hook can trigger out of order due to its dynamic nature, and with embedded applications will only work for the application that is rendering.

  $app->hook(before_render => sub {
    my ($c, $args) = @_;
    ...
  });

Mostly used for pre-processing arguments passed to the renderer. (Passed the current controller object and the render arguments)

after_render

Emitted after content has been generated by the renderer that is not partial. Note that this hook can trigger out of order due to its dynamic nature, and with embedded applications will only work for the application that is rendering.

  $app->hook(after_render => sub {
    my ($c, $output, $format) = @_;
    ...
  });

Mostly used for post-processing dynamically generated content. (Passed the current controller object, a reference to the content and the format)

after_dispatch

Emitted in reverse order after a response has been rendered. Note that this hook can trigger out of order due to its dynamic nature, and with embedded applications will only work for the application that is rendering.

  $app->hook(after_dispatch => sub {
    my $c = shift;
    ...
  });

Useful for rewriting outgoing responses and other post-processing tasks. (Passed the current controller object)

around_dispatch

Emitted right before the "before_dispatch" hook and wraps around the whole dispatch process, so you have to manually forward to the next hook if you want to continue the chain. Default exception handling with "render_exception" in Mojolicious::Controller is the first hook in the chain and a call to "dispatch" the last, yours will be in between.

  $app->hook(around_dispatch => sub {
    my ($next, $c) = @_;
    ...
    $next->();
    ...
  });

This is a very powerful hook and should not be used lightly, it allows you for example to customize application wide exception handling, consider it the sledgehammer in your toolbox. (Passed a callback leading to the next hook and the default controller object)

ATTRIBUTES

Mojolicious inherits all attributes from Mojo and implements the following new ones.

commands

  my $commands = $app->commands;
  $app         = $app->commands(Mojolicious::Commands->new);

Command line interface for your application, defaults to a Mojolicious::Commands object.

  # Add another namespace to load commands from
  push @{$app->commands->namespaces}, 'MyApp::Command';

controller_class

  my $class = $app->controller_class;
  $app      = $app->controller_class('Mojolicious::Controller');

Class to be used for the default controller, defaults to Mojolicious::Controller.

mode

  my $mode = $app->mode;
  $app     = $app->mode('production');

The operating mode for your application, defaults to a value from the MOJO_MODE and PLACK_ENV environment variables or development. Right before calling "startup", Mojolicious will pick up the current mode, name the log file after it and raise the log level from debug to info if it has a value other than development.

moniker

  my $moniker = $app->moniker;
  $app        = $app->moniker('foo_bar');

Moniker of this application, often used as default filename for configuration files and the like, defaults to decamelizing the application class with "decamelize" in Mojo::Util.

plugins

  my $plugins = $app->plugins;
  $app        = $app->plugins(Mojolicious::Plugins->new);

The plugin manager, defaults to a Mojolicious::Plugins object. See the "plugin" method below if you want to load a plugin.

  # Add another namespace to load plugins from
  push @{$app->plugins->namespaces}, 'MyApp::Plugin';

renderer

  my $renderer = $app->renderer;
  $app         = $app->renderer(Mojolicious::Renderer->new);

Used in your application to render content, defaults to a Mojolicious::Renderer object. The two main renderer plugins Mojolicious::Plugin::EPRenderer and Mojolicious::Plugin::EPLRenderer contain more information.

  # Add another "templates" directory
  push @{$app->renderer->paths}, '/home/sri/templates';

  # Add another class with templates in DATA section
  push @{$app->renderer->classes}, 'Mojolicious::Plugin::Fun';

routes

  my $routes = $app->routes;
  $app       = $app->routes(Mojolicious::Routes->new);

The router, defaults to a Mojolicious::Routes object. You use this in your startup method to define the url endpoints for your application.

  # Add routes
  my $r = $app->routes;
  $r->get('/foo/bar')->to('test#foo', title => 'Hello Mojo!');
  $r->post('/baz')->to('test#baz');

  # Add another namespace to load controllers from
  push @{$app->routes->namespaces}, 'MyApp::Controller';

secrets

  my $secrets = $app->secrets;
  $app        = $app->secrets(['passw0rd']);

Secret passphrases used for signed cookies and the like, defaults to the "moniker" of this application, which is not very secure, so you should change it!!! As long as you are using the insecure default there will be debug messages in the log file reminding you to change your passphrase. Only the first passphrase is used to create new signatures, but all of them for verification. So you can increase security without invalidating all your existing signed cookies by rotating passphrases, just add new ones to the front and remove old ones from the back.

  # Rotate passphrases
  $app->secrets(['new_passw0rd', 'old_passw0rd', 'very_old_passw0rd']);

sessions

  my $sessions = $app->sessions;
  $app         = $app->sessions(Mojolicious::Sessions->new);

Signed cookie based session manager, defaults to a Mojolicious::Sessions object. You can usually leave this alone, see "session" in Mojolicious::Controller for more information about working with session data.

  # Change name of cookie used for all sessions
  $app->sessions->cookie_name('mysession');

static

  my $static = $app->static;
  $app       = $app->static(Mojolicious::Static->new);

For serving static files from your public directories, defaults to a Mojolicious::Static object.

  # Add another "public" directory
  push @{$app->static->paths}, '/home/sri/public';

  # Add another class with static files in DATA section
  push @{$app->static->classes}, 'Mojolicious::Plugin::Fun';

types

  my $types = $app->types;
  $app      = $app->types(Mojolicious::Types->new);

Responsible for connecting file extensions with MIME types, defaults to a Mojolicious::Types object.

  # Add custom MIME type
  $app->types->type(twt => 'text/tweet');

validator

  my $validator = $app->validator;
  $app          = $app->validator(Mojolicious::Validator->new);

Validate parameters, defaults to a Mojolicious::Validator object.

METHODS

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

build_tx

  my $tx = $app->build_tx;

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

defaults

  my $hash = $app->defaults;
  my $foo  = $app->defaults('foo');
  $app     = $app->defaults({foo => 'bar'});
  $app     = $app->defaults(foo => 'bar');

Default values for "stash" in Mojolicious::Controller, assigned for every new request.

  # Remove value
  my $foo = delete $app->defaults->{foo};

dispatch

  $app->dispatch(Mojolicious::Controller->new);

The heart of every Mojolicious application, calls the "static" and "routes" dispatchers for every request and passes them a Mojolicious::Controller object.

handler

  $app->handler(Mojo::Transaction::HTTP->new);
  $app->handler(Mojolicious::Controller->new);

Sets up the default controller and emits the "around_dispatch" hook for every request.

helper

  $app->helper(foo => sub {...});

Add a new helper that will be available as a method of the controller object and the application object, as well as a function in ep templates.

  # Helper
  $app->helper(cache => sub { state $cache = {} });

  # Controller/Application
  $self->cache->{foo} = 'bar';
  my $result = $self->cache->{foo};

  # Template
  % cache->{foo} = 'bar';
  %= cache->{foo}

hook

  $app->hook(after_dispatch => sub {...});

Extend Mojolicious with hooks, which allow code to be shared with all requests indiscriminately, for a full list of available hooks see "HOOKS".

  # Dispatchers will not run if there's already a response code defined
  $app->hook(before_dispatch => sub {
    my $c = shift;
    $c->render(text => 'Skipped static file server and router!')
      if $c->req->url->path->to_route =~ /do_not_dispatch/;
  });

new

  my $app = Mojolicious->new;

Construct a new Mojolicious application and call "startup". Will automatically detect your home directory and set up logging based on your current operating mode. Also sets up the renderer, static file server, a default set of plugins and an "around_dispatch" hook with the default exception handling.

plugin

  $app->plugin('some_thing');
  $app->plugin('some_thing', foo => 23);
  $app->plugin('some_thing', {foo => 23});
  $app->plugin('SomeThing');
  $app->plugin('SomeThing', foo => 23);
  $app->plugin('SomeThing', {foo => 23});
  $app->plugin('MyApp::Plugin::SomeThing');
  $app->plugin('MyApp::Plugin::SomeThing', foo => 23);
  $app->plugin('MyApp::Plugin::SomeThing', {foo => 23});

Load a plugin, for a full list of example plugins included in the Mojolicious distribution see "PLUGINS" in Mojolicious::Plugins.

start

  $app->start;
  $app->start(@ARGV);

Start the command line interface for your application, for a full list of commands available by default see "COMMANDS" in Mojolicious::Commands.

  # Always start daemon and ignore @ARGV
  $app->start('daemon', '-l', 'http://*:8080');

startup

  $app->startup;

This is your main hook into the application, it will be called at application startup. Meant to be overloaded in a subclass.

  sub startup {
    my $self = shift;
    ...
  }

AUTOLOAD

In addition to the "ATTRIBUTES" and "METHODS" above you can also call helpers on Mojolicious objects. This includes all helpers from Mojolicious::Plugin::DefaultHelpers and Mojolicious::Plugin::TagHelpers. Note that application helpers are always called with a new default controller object, so they can't depend on or change controller state, which includes request, response and stash.

  $app->log->debug($app->dumper({foo => 'bar'}));
