Mojolicious::Plugin::Config - Perl-ish configuration plugin


  # myapp.conf (it's just Perl returning a hash)
    # Just a value
    foo => "bar",

    # Nested data structures are fine too
    baz => ['♥'],

    # You have full access to the application
    music_dir => app->home->child('music')

  # Mojolicious
  my $config = $app->plugin('Config');
  say $config->{foo};

  # Mojolicious::Lite
  my $config = plugin 'Config';
  say $config->{foo};

  # foo.html.ep
  %= config->{foo}

  # The configuration is available application-wide
  my $config = app->config;
  say $config->{foo};

  # Everything can be customized with options
  my $config = plugin Config => {file => '/etc/myapp.stuff'};


Mojolicious::Plugin::Config is a Perl-ish configuration plugin.

The application object can be accessed via $app or the app function, strict, warnings, utf8 and Perl 5.16 features are automatically enabled. A default configuration filename in the application home directory will be generated from the value of "moniker" in Mojolicious ($moniker.conf). You can extend the normal configuration file $moniker.conf with mode specific ones like $moniker.$mode.conf, which will be detected automatically.

These configuration values are currently reserved:


If this configuration value has been set in "config" in Mojolicious when this plugin is loaded, it will not do anything besides loading deployment specific plugins.

  plugins => [{SetUserGroup => {user => 'sri', group => 'staff'}}]

One or more deployment specific plugins that should be loaded right after this plugin has been loaded.

The code of this plugin is a good example for learning to build new plugins, you're welcome to fork it.

See "PLUGINS" in Mojolicious::Plugins for a list of plugins that are available by default.


Mojolicious::Plugin::Config supports the following options.


  # Mojolicious::Lite
  plugin Config => {default => {foo => 'bar'}};

Default configuration, making configuration files optional.


  # Mojolicious::Lite
  plugin Config => {ext => 'stuff'};

File extension for generated configuration filenames, defaults to conf.


  # Mojolicious::Lite
  plugin Config => {file => 'myapp.conf'};
  plugin Config => {file => '/etc/foo.stuff'};

Path to configuration file, absolute or relative to the application home directory, defaults to the value of the MOJO_CONFIG environment variable or $moniker.conf in the application home directory.


Mojolicious::Plugin::Config inherits all methods from Mojolicious::Plugin and implements the following new ones.


  $plugin->load($file, $conf, $app);

Loads configuration file and passes the content to "parse".

  sub load ($self, $file, $conf, $app) {
    return $self->parse($content, $file, $conf, $app);


  $plugin->parse($content, $file, $conf, $app);

Parse configuration file.

  sub parse ($self, $content, $file, $conf, $app) {
    return $hash;


  my $config = $plugin->register(Mojolicious->new);
  my $config = $plugin->register(Mojolicious->new, {file => '/etc/app.conf'});

Register plugin in Mojolicious application and merge configuration.
