This repo provides HTTP RoundTrippers I find myself reimplementing all the time.

bearer

This package provides an http.RoundTripper that sets a bearer authorization token on all requests.

logging

This package provides an http.RoundTripper that logs all requests it makes.

fn

This package provides a func to create an http.RoundTripper from a func.

client := &http.Client{
  Transport: fn.RoundTripperFunc(func(r *http.Request) (*http.Response, error) {
    // this func is called when the client RoundTrips.
  })
}
