Blacksmith is extensible by adding middleware between the resource contracts and the real http query.
For example, requests may share a security secret that make not parts of the contract of a route.
Middleware may be shared by all clients, such as prometheus middleware that catch all the traffic for monitoring, or may be added on client to add credentials per users.
Note
Users can create their own middleware but blacksmith comes with its lists of usefull middlewares listed here.
