With go there is really less emphasis on taking advantage of a web framework like expressjs (look at go alternatives like gin) and building server functionality from the std library (since everything you need is there). I wrote a small helper library to help with template rendering if you're interested in looking at the source to see how you can take advantage of the std library for templating: https://github.com/dannav/migo

When I was learning Go, Negroni was where I left off and felt like what you may be looking for as a next step: https://github.com/urfave/negroni (I"m sure someone more experienced can provide more context or other / better links -- thought this would be a better answer than none until then)
