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.
If the configuration value config_override has been set in "config" in Mojolicious when this plugin is loaded, it will not do anything.
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.
