To each their own, but I personally prefer the lego-building block-approach instead of the kitchen-sink approach of bigger frameworks. In Go at least, this scales quite nicely with your code IMO.

I use a couple of thin layers over net/http:

Gorilla mux: https://github.com/gorilla/mux

... Gets me easy route params and HTTP method filtering.

Negroni for middleware: https://github.com/urfave/negroni

... Super easy to roll your own, plus there's a bunch of random off-the-shelf middlewares that people have put together (see their README).

For talking with my DB, I just use sqlx (and sqlmock in my unit tests).
