Mojolicious - Real-time web framework
# 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!');
}
Take a look at our excellent documentation in Mojolicious::Guides!
Mojolicious inherits all attributes from Mojo and implements the following new ones.
commandsmy $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 the value of the MOJO_MODE environment variable or development. You can also add per mode logic to your application by defining methods named ${mode}_mode in the application class, which will be called right before startup.
sub development_mode {
my $self = shift;
...
}
sub production_mode {
my $self = shift;
...
}
Right before calling startup and mode specific methods, 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.
pluginsmy $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';
renderermy $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';
routesmy $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.
sub startup {
my $self = shift;
my $r = $self->routes;
$r->get('/:controller/:action')->to('test#welcome');
}
secret my $secret = $app->secret;
$app = $app->secret('passw0rd');
A secret passphrase used for signed cookies and the like, defaults to the application name which is not very secure, so you should change it!!! As long as you are using the unsecure default there will be debug messages in the log file reminding you to change your passphrase.
sessionsmy $sessions = $app->sessions; $app = $app->sessions(Mojolicious::Sessions->new);
Simple signed cookie based sessions, 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.
staticmy $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';
typesmy $types = $app->types; $app = $app->types(Mojolicious::Types->new);
Responsible for connecting file extensions with MIME types, defaults to a Mojolicious::Types object.
$app->types->type(twt => 'text/tweet');
Mojolicious inherits all methods from Mojo and implements the following new ones.
newmy $app = Mojolicious->new;
Construct a new Mojolicious application, calling ${mode}_mode and startup in the process. Will automatically detect your home directory and set up logging based on your current operating mode. Also sets up the renderer, static dispatcher and a default set of plugins.
build_txmy $tx = $app->build_tx;
Transaction builder, defaults to building a Mojo::Transaction::HTTP object.
defaults my $defaults = $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.
# Manipulate defaults
$app->defaults->{foo} = 'bar';
my $foo = $app->defaults->{foo};
delete $app->defaults->{foo};
dispatch$app->dispatch($c);
The heart of every Mojolicious application, calls the static and routes dispatchers for every request and passes them a Mojolicious::Controller object.
handler$app->handler($tx); $app->handler($c);
Sets up the default controller and calls process 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(add => sub { $_[1] + $_[2] });
# Controller/Application
my $result = $self->add(2, 3);
# Template
%= add 2, 3
hook $app->hook(after_dispatch => sub {...});
Extend Mojolicious with 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 dispatchers!')
if $c->req->url->path->contains('/do_not_dispatch');
});
These hooks are currently available and are emitted in the listed order:
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, just note that it will not work for embedded applications. (Passed the transaction and application object)
Emitted right before the static dispatcher 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)
Emitted in reverse order after the static dispatcher determined if a static file should be served and before the router starts its work.
$app->hook(after_static_dispatch => sub {
my $c = shift;
...
});
Mostly used for custom dispatchers and post-processing static file responses. (Passed the default controller object)
Emitted in reverse order after a response has been rendered. Note that this hook can trigger before after_static_dispatch due to its dynamic nature.
$app->hook(after_dispatch => sub {
my $c = shift;
...
});
Useful for rewriting outgoing responses and other post-processing tasks. (Passed the current controller object)
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 to customize application wide exception handling for example, consider it the sledgehammer in your toolbox. (Passed a closure leading to the next hook and the default controller object)
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);
$app->plugin('MyApp::Plugin::SomeThing', {foo => 23});
Load a plugin with "register_plugin" in Mojolicious::Plugins.
These plugins are included in the Mojolicious distribution as examples:
Change the application charset.
Perl-ish configuration files.
General purpose helper collection, loaded automatically.
Renderer for plain embedded Perl templates, loaded automatically.
Renderer for more sophisiticated embedded Perl templates, loaded automatically.
Route condition for all kinds of headers, loaded automatically.
Internationalization helpers.
JSON configuration files.
Mount whole Mojolicious applications.
Renderer for POD files and documentation browser.
Add an X-Powered-By header to outgoing responses, loaded automatically.
Log timing information, loaded automatically.
Template specific helper collection, loaded automatically.
start$app->start; $app->start(@ARGV);
Start the command line interface for your application with "start" 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;
...
}
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 controller_class object, so they can't depend on or change controller state, which includes request, response and stash.
$app->log->debug($app->dumper({foo => 'bar'}));
