Pro High performance
gocraft/web is a minimalistic web framework which adds routing to the
net/http package from the standard library. Even so, web.go tries to compensate for the small abstraction that it offers by structuring routes in a tree instead of a list. As such, it's a very fast framework which makes it a good choice in applications where good performance is key.
Con Doesn't add a lot of functionality on top of the standard library
Most of the tasks that gocraft/web is used for can be completed with standard library support without adding the overhead of an additional external library and without having the risk of web.co development being abandoned one day.
