Mojolicious::Plugin::CHI - Use CHI Caches in Mojolicious

# Mojolicious
$app->plugin(CHI => {
  MyCache => {
    driver     => 'FastMmap',
    root_dir   => '/cache',
    cache_size => '20m'
  }
});

# Mojolicious::Lite
plugin 'CHI' => {
  default => {
    driver => 'Memory',
    global => 1
  }
};

# In Controllers:
$c->chi('MyCache')->set(my_key => 'This is my value');
print $c->chi('MyCache')->get('my_key');

# Using the default cache
$c->chi->set(from_memory => 'With love!');
print $c->chi->get('from_memory');

Mojolicious::Plugin::CHI is a simple plugin to work with CHI caches within Mojolicious.

# Mojolicious
$app->plugin(CHI => {
  MyCache => {
    driver     => 'FastMmap',
    root_dir   => '/cache',
    cache_size => '20m'
  },
  default => {
    driver => 'Memory',
    global => 1
  },
  namespaces => 1
});

# Mojolicious::Lite
plugin 'CHI' => {
  default => { driver => 'Memory', global => 1 }
};

# Or in your config file
{
  CHI => {
    default => {
      driver => 'Memory',
      global => 1
    }
  }
}

Called when registering the plugin. On creation, the plugin accepts a hash of cache names associated with CHI objects. All cache handles are qualified CHI namespaces. You can omit this mapping by passing a namespaces parameter with a false value. The handles have to be unique, i.e. you can't have multiple different default caches in mounted applications using Mojolicious::Plugin::Mount. Logging defaults to the application log, but can be overridden using on_get_error and on_set_error.

All parameters can be set as part of the configuration file with the key CHI or on registration (that can be overwritten by configuration).

Use custom CHI subclasses by passing a chi_class parameter with the class name of a CHI subclass.

# In Controllers:
$c->chi('MyCache')->set(my_key => 'This is my value', '10 min');
print $c->chi('MyCache')->get('my_key');
print $c->chi->get('from_default_cache');

Returns a CHI handle if registered. Accepts the name of the registered cache. If no cache handle name is given, a cache handle name default is assumed.

The following commands are available when the plugin is registered.

perl app.pl chi list

List all CHI caches associated with your application.

perl app.pl chi purge mycache

Remove all expired entries from the cache namespace.

perl app.pl chi clear mycache

Remove all entries from the cache namespace.

perl app.pl chi expire mykey
perl app.pl chi expire mycache mykey

Set the expiration date of a key to the past. This does not necessarily delete the data, but makes it unavailable using get.

perl app.pl chi remove mykey
perl app.pl chi remove mycache mykey

Remove a key from the cache.

Mojolicious, CHI.

Note: Old versions of CHI had a lot of dependencies. It was thus not recommended to use this plugin in a CGI environment. Since new versions of CHI use Moo instead of Moose, more use cases may be possible.
