Pre/post processing of files posted to a node

Hi,
is there any standard way of implementing hooks into the process of storing new data? I’d like to send the data for further processing prior to having it stored in IPFS. I was hoping I can avoid creating proxy for the entire IPFS API.

Does not have to anything sophisticated, simply pass the data to some service. No need to handle response or anything like that.

thanks for help
