NAME¶

Mojolicious::Plugin::JSONConfig - JSON configuration plugin

SYNOPSIS¶

  # myapp.json (it's just JSON with embedded Perl)
  {
    %# 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('JSONConfig');
  say $config->{foo};
  # Mojolicious::Lite
  my $config = plugin 'JSONConfig';
  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 JSONConfig => {file => '/etc/myapp.conf'};

DESCRIPTION¶

Mojolicious::Plugin::JSONConfig is a JSON configuration plugin that preprocesses its input with Mojo::Template.

The application object can be accessed via $app or the "app" function. A default configuration filename in the application home directory will be generated from the value of "moniker" in Mojolicious ("$moniker.json"). You can extend the normal configuration file "$moniker.json" with "mode" specific ones like "$moniker.$mode.json", which will be detected automatically.

These configuration values are currently reserved:

"config_override"

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"

  "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.
