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::Controller::Foo;
         use Mojo::Base 'Mojolicious::Controller';

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

DESCRIPTION

       An amazing real-time web framework built on top of the powerful Mojo web development toolkit. With
       support for RESTful routes, plugins, commands, Perl-ish templates, content negotiation, session
       management, form validation, testing framework, static file server, "CGI"/"PSGI" detection, first class
       Unicode support and much more for you to discover.

       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, because
       only the host application gets to build transactions. (Passed the transaction and application object)

   around_dispatch
       Emitted right after a new request has been received 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 "reply->exception" in Mojolicious::Plugin::DefaultHelpers 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 to, for example, 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)

   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 executed 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. Note that this hook can trigger more than once
       for the same request if there are nested routes. (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 will be assigned to the response. 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 generated. 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 generating the response.

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

       Useful for rewriting outgoing responses and other post-processing tasks.  (Passed the current 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. Note that this class
       needs to have already been loaded before the first request arrives.

   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.

         # Portably generate path relative to home directory
         my $path = $app->home->child('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. The level will default to "debug"
       if the "mode" is "development", or "info" otherwise. All messages will be written to "STDERR", or a
       "log/$mode.log" file if a "log" directory exists.

         # Log debug message
         $app->log->debug('It works');

   max_request_size
         my $max = $app->max_request_size;
         $app    = $app->max_request_size(16777216);

       Maximum request size in bytes, defaults to the value of "max_message_size" in Mojo::Message. Setting the
       value to 0 will allow requests of indefinite size. Note that increasing this value can also drastically
       increase memory usage, should you for example attempt to parse an excessively large request body with the
       methods "dom" in Mojo::Message or "json" in Mojo::Message.

   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".

   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 to render content, defaults to a Mojolicious::Renderer object. For more information about how to
       generate content see Mojolicious::Guides::Rendering.

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

         # Add another "templates" directory with higher precedence
         unshift @{$app->renderer->paths}, '/home/sri/themes/blue/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::MyController';

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

       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 "public" directory with higher precedence
         unshift @{$app->static->paths}, '/home/sri/themes/blue/public';

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

         # Remove built-in favicon
         delete $app->static->extra->{'favicon.ico'};

   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');

   ua
         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('example.com')->result->body;

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

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

         # Add validation check
         $app->validator->add_check(foo => sub {
           my ($validation, $name, $value) = @_;
           return $value ne 'foo';
         });

         # Add validation filter
         $app->validator->add_filter(quotemeta => sub {
           my ($validation, $name, $value) = @_;
           return quotemeta $value;
         });

METHODS

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

   build_controller
         my $c = $app->build_controller;
         my $c = $app->build_controller(Mojo::Transaction::HTTP->new);
         my $c = $app->build_controller(Mojolicious::Controller->new);

       Build default controller object with "controller_class".

         # Render template from application
         my $foo = $app->build_controller->render_to_string(template => 'foo');

   build_tx
         my $tx = $app->build_tx;

       Build Mojo::Transaction::HTTP object and emit "after_build_tx" hook.

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

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

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

         # Assign multiple values at once
         $app->defaults(foo => 'test', bar => 23);

   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 or replace a helper that will be available as a method of the controller object and the application
       object, as well as a function in "ep" templates. For a full list of helpers that are available by default
       see Mojolicious::Plugin::DefaultHelpers and Mojolicious::Plugin::TagHelpers.

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

         # Application
         $app->cache->{foo} = 'bar';
         my $result = $app->cache->{foo};

         # Controller
         $c->cache->{foo} = 'bar';
         my $result = $c->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;
         my $app = Mojolicious->new(moniker => 'foo_bar');
         my $app = Mojolicious->new({moniker => 'foo_bar'});

       Construct a new Mojolicious application and call "startup". Will automatically detect your home
       directory. 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 that are available by
       default see "COMMANDS" in Mojolicious::Commands.  Note that the options "-h"/"--help", "--home" and
       "-m"/"--mode", which are shared by all commands, will be parsed from @ARGV during compile time.

         # Always start daemon
         $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.

         # Call helper
         say $app->dumper({foo => 'bar'});

         # Longer version
         say $app->build_controller->helpers->dumper({foo => 'bar'});
