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.
//... 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 }
