I ma getting redis.get is not a function
api.config.redis.client.llen( key, function(err, length){
api.log('length was ' + length);
} );
api.redis.clients.client
inside an AH initializer, task or action, you'll have access to the `api` object. The redis connection (in v14), configured in config/redis.js, is available with api.redis.clients.client.
So to make a call to find the list length in redis, you'd make a call like
api.redis.clients.client.llen( key, function(err, length){
api.log('length was ' + length);
} );
