HTTP Error Example

Real-world pattern

HTTP handlers often use this pattern:

func handler(w http.ResponseWriter, r *http.Request) {
    data, err := fetchData()
    if err != nil {
        http.Error(w, err.Error(), http.StatusInternalServerError)
        return
    }
    json.NewEncoder(w).Encode(data)
}

Return early on error, respond normally on success. The http.Error function writes an error response.
