# Mojolicious
my $config = $app->plugin('JSONConfig');
say $config->{foo};
# Mojolicious::Lite
my $config = plugin 'JSONConfig';
say $config->{foo};
# foo.html.ep

#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.
