Overview

Public: a batch middleware which surpresses the response from a call. If you know you don’t need a response (for instance, for a POST or PUT), you can add silent: true (or any truthy value, like 1) to your operation to surpress all output for successful requests. Failed requests (status != 2xx) will still return information.
