Because you're adding a new listener every single time you request item info.
 
Just use the callback and you won't need to worry about it.

node-globaloffensive is using an option where instead of underscores, you should provide protobuf fields in camelCase. Basically, just remove the underscores and capitalize the next letter.
 
However, I've added that functionality in v1.1.0.

WebStorm is giving you an error because csgo doesn't exist when you're trying to listen for an event on it. Create your GlobalOffensive object at the same time as when you create your SteamUser object.

WebStorm sometimes has trouble resolving Node dependencies.
 
Do you have the Node.js plugin installed in WebStorm?
