+### Serving Single Page Applications
+
+Most of the time it makes sense to serve your SPA on a separate web server from your API,
+but sometimes it's desirable to serve them both from one place. It's possible to write a simple
+handler for serving your SPA (for use with React Router's [BrowserRouter](https://reacttraining.com/react-router/web/api/BrowserRouter) for example), and leverage
+mux's powerful routing for your API endpoints.
+
+```go
+package main
+
+import (
+ "encoding/json"
+ "log"
+ "net/http"
+ "os"
+ "path/filepath"
+ "time"
+
+ "github.com/gorilla/mux"
+)
+
+// spaHandler implements the http.Handler interface, so we can use it
+// to respond to HTTP requests. The path to the static directory and
+// path to the index file within that static directory are used to
+// serve the SPA in the given static directory.
+type spaHandler struct {
+ staticPath string
+ indexPath string
+}
+
+// ServeHTTP inspects the URL path to locate a file within the static dir
+// on the SPA handler. If a file is found, it will be served. If not, the
+// file located at the index path on the SPA handler will be served. This
+// is suitable behavior for serving an SPA (single page application).
+func (h spaHandler) ServeHTTP(w http.ResponseWriter, r *http.Request) {
+ // get the absolute path to prevent directory traversal
+ path, err := filepath.Abs(r.URL.Path)
+ if err != nil {
+ // if we failed to get the absolute path respond with a 400 bad request
+ // and stop
+ http.Error(w, err.Error(), http.StatusBadRequest)
+ return
+ }
+
+ // prepend the path with the path to the static directory
+ path = filepath.Join(h.staticPath, path)
+
+ // check whether a file exists at the given path
+ _, err = os.Stat(path)
+ if os.IsNotExist(err) {
+ // file does not exist, serve index.html
+ http.ServeFile(w, r, filepath.Join(h.staticPath, h.indexPath))
+ return
+ } else if err != nil {
+ // if we got an error (that wasn't that the file doesn't exist) stating the
+ // file, return a 500 internal server error and stop
+ http.Error(w, err.Error(), http.StatusInternalServerError)
+ return
+ }
+
+ // otherwise, use http.FileServer to serve the static dir
+ http.FileServer(http.Dir(h.staticPath)).ServeHTTP(w, r)
+}
+
+func main() {
+ router := mux.NewRouter()
+
+ router.HandleFunc("/api/health", func(w http.ResponseWriter, r *http.Request) {
+ // an example API handler
+ json.NewEncoder(w).Encode(map[string]bool{"ok": true})
+ })
+
+ spa := spaHandler{staticPath: "build", indexPath: "index.html"}
+ router.PathPrefix("/").Handler(spa)
+
+ srv := &http.Server{
+ Handler: router,
+ Addr: "127.0.0.1:8000",
+ // Good practice: enforce timeouts for servers you create!
+ WriteTimeout: 15 * time.Second,
+ ReadTimeout: 15 * time.Second,
+ }
+
+ log.Fatal(srv.ListenAndServe())
+}
+```
