How to Serve Static Content from the Root URL Using Go's Gorilla Mux?

Serving Static Content from Root URL Using Gorilla Toolkit

Your goal is to serve static content, such as HTML, CSS, and JavaScript, from a root URL using the Gorilla toolkit for Go. However, you're encountering 404 errors when accessing files within subdirectories.

To address this issue, let's modify the code as suggested in the provided answer:

func main() {
    r := mux.NewRouter()
    r.HandleFunc("/search/{searchTerm}", Search)
    r.HandleFunc("/load/{dataId}", Load)
    r.PathPrefix("/").Handler(http.FileServer(http.Dir("./static/")))
    http.ListenAndServe(":8100", r)
}

By using PathPrefix, we specify that the FileServer handler should handle all requests with a prefix of /. This ensures that the static files located within the ./static/ directory are served from the root URL (e.g., http://localhost:8100/).

This modification should resolve the 404 errors and allow you to successfully access the HTML, CSS, and JavaScript files from the root URL.
