HostRouter
hostrouter
is a small Go pkg to let you route traffic to different http handlers or routers
based on the request host. This is useful to mount multiple routers on a single server.
Basic usage example
//...
func main() {
r := chi.NewRouter()
r.Use(middleware.RequestID)
r.Use(middleware.RealIP)
r.Use(middleware.Logger)
r.Use(middleware.Recoverer)
hr := hostrouter.New()
// Requests to api.domain.com
hr.Map("", apiRouter()) // default
hr.Map("api.domain.com", apiRouter())
// Requests to doma.in
hr.Map("doma.in", shortUrlRouter())
// Requests to *.doma.in
hr.Map("*.doma.in", shortUrlRouter())
// Requests to host that isn't defined above
hr.Map("*", everythingElseRouter())
// Mount the host router
r.Mount("/", hr)
http.ListenAndServe(":3333", r)
}
// Router for the API service
func apiRouter() chi.Router {
r := chi.NewRouter()
r.Get("/", apiIndexHandler)
// ...
return r
}
// Router for the Short URL service
func shortUrlRouter() chi.Router {
r := chi.NewRouter()
r.Get("/", shortIndexHandler)
// ...
return r
}
