It is not very difficult to do what you request. You don't have to base64 encode it or anything (it will just make it harder for you to edit.).

Below is an example of how to output a javascript file with correct mime type:

package main

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

const jsFile = `alert('Hello World!');`

func main() {
    http.HandleFunc("/file.js", JsHandler)

    log.Fatal(http.ListenAndServe(":8080", nil))
}

func JsHandler(w http.ResponseWriter, r *http.Request) {
    // Getting the headers so we can set the correct mime type
    headers := w.Header()
    headers["Content-Type"] = []string{"application/javascript"}
    fmt.Fprint(w, jsFile)
}
