Serve homepage and static content from root

Question

In Golang, how do I serve static content out of the root directory while still having a root directory handler for serving the homepage.

Use the following simple web

One thing I thought of that might help you is that you can create your own ServeMux. I added to your example so that chttp is a ServeMux that you can have serve static files. The HomeHandler then checks to see if it should serve a file or not. I just check for a "." but you could do a lot of things. Just an idea, might not be what you are looking for.

package main

import (
    "fmt"
    "net/http"
    "strings"
)   

var chttp = http.NewServeMux()

func main() {

    chttp.Handle("/", http.FileServer(http.Dir("./")))

    http.HandleFunc("/", HomeHandler) // homepage
    http.ListenAndServe(":8080", nil)
}   

func HomeHandler(w http.ResponseWriter, r *http.Request) {

    if (strings.Contains(r.URL.Path, ".")) {
        chttp.ServeHTTP(w, r)
    } else {
        fmt.Fprintf(w, "HomeHandler")
    }   
}
