How to hide express HTTP request logging?

In the aspect of user privacy server should not log the txhash url when user browse them....

I'm not sure about the privacy aspect unless people are also logging and tracking IPs. Otherwise this is simply no different than an access log and very useful for development purposes.

I'd instead would like to change the topic of discussion away from privacy and instead think about the expandability of having loglevels. The inclusion of all requests is pretty verbose, whereas most would rather just have errors/warnings.

Correct, we should be able to exclude non error/warning messages.
