NAME

Curio::Role::CHI - Build Curio classes around CHI.

SYNOPSIS

Create a Curio class:

package MyApp::Service::Cache;

use Curio role => '::CHI';

use Exporter qw( import );
our @EXPORT = qw( myapp_cache );

add_key geo_ip => (
    driver => 'Memory',
    global => 0,
);

sub myapp_cache {
    return __PACKAGE__->fetch( @_ )->chi();
}

1;

Then use your new Curio class elsewhere:

use MyApp::Service::Cache;

my $chi = myapp_cache('geo_ip');

DESCRIPTION

This role provides all the basics for building a Curio class which wraps around CHI.

Fun fact, this "SYNOPSIS" is functionally identical to "SYNOPSIS" in Curio.

ATTRIBUTES

chi

my $chi = MyApp::Service::Cache->fetch('geo_ip)->chi();

Holds the CHI object.

CACHING

This role sets the "does_caching" in Curio::Factory and "cache_per_process" in Curio::Factory features.

cache_per_process is important to set since there are quite a few CHI drivers which do not like to be re-used across processes.

You can of course disable these features.

does_caching 0;
cache_per_process 0;

NO KEYS

If you'd like to create a CHI Curio class which exposes a single CHI object and does not support keys then here's a slightly altered version of the "SYNOPSIS" to get you started.

Create a Curio class:

package MyApp::Service::GeoIPCache;

use Curio role => '::CHI';

use Exporter qw( import );
our @EXPORT = qw( myapp_geo_ip_cache );

default_arguments (
    driver => 'Memory',
    global => 0,
);

sub myapp_geo_ip_cache {
    return __PACKAGE__->fetch( @_ )->chi();
}

1;

Then use your new Curio class elsewhere:

use MyApp::Service::GeoIPCache;

my $chi = myapp_geo_ip_cache();
