I am using Golang, Negroni, and Gorilla mux for a web api server. I have my api routes under /api and I am using Negroni to serve static files from my /public directory using urls under /. I would like to serve my index.html file (containing a single page javascript application) not only if it is requested by name or as the index file, but also if the request would otherwise result in a 404 because it doesn't correspond to a route or a file in the /public directory. This is so that those URLs will load the webapp which will transition to the correct route (client side javascript history/pushState) or else give a not found error if that resource doesn't exist. Is there a way to get Negroni's static middleware or Gorilla mux to do this?

The
Router
type in the mux library has aNotFoundHandler
field of typehttp.Handler
. This would allow you to handle a unmatched route as you see fit:// NotFoundHandler overrides the default not found handler func NotFoundHandler(w http.ResponseWriter, r *http.Request) { // You can use the serve file helper to respond to 404 with // your request file. http.ServeFile(w, r, "public/index.html") } func main() { r := mux.NewRouter() r.NotFoundHandler = http.HandlerFunc(NotFoundHandler) // Register other routes or setup negroni log.Fatal(http.ListenAndServe(":8080", r)) }
