Building web services in Go
summary
Shows concrete patterns: a marshalled wrapper using reflection that decodes request types and encodes JSON responses with Go-style error values; a tree router with wildcard segments and method dispatch that returns 404/405; middleware composed by wrapping handlers and overriding the ResponseWriter to implement logging, metrics and short-circuiting; and a graceful shutdown built on ConnState and SetKeepAlivesEnabled so active requests finish within a bounded grace period.
