The more you get to know Go's stdlib the less and less youll think a web framework is necessary.
Youll find that utilizing http Round Tripper along with the Handler interface in the http library will make middleware easy.
Youll eventually dig into filepath and path methods for extracting path parameters from url paths.
And logging and recovery will be a concept youll need to extend outside of just http and into the rest of your application.
I totally advise new comers to use a web framework, but in the long run, you probably wont want too.
