nrsc - Resource Compiler for Go

nrsc a directory of resource into a Go source file so you can still deploy a single executable as a web server with all the CSS, image files, JS ... included.


go get bitbucket.org/tebeka/nrsc

Also grab the nrsc script from here

And you'll need zip somewhere in your path.


go build
nrsc <executable> <resource dir>


The nrsc package has the following interface

nrsc.Handle(prefix string)

This will register with the net/http module to handle all paths starting with prefix.

When a request is handled, prefix is stripped and then a resource is located and served.

Resource that are not found will cause an HTTP 404 response.

nrsc.Get(path string) Resource
Will return a resource interface (or nil if not found) (see resource interface below). This allows you more control on how to serve.
LoadTemplates(t *template.Template, filenames ...string) (*template.Template, error)
Will load named templates from resources. If the argument "t" is nil, it is created from the first resource.

func Size() int64

import (


func indexHandler(w http.ResponseWriter, req *http.Request) {
        fmt.Fprintf(w, "Hello World\n")

func main() {
        http.HandleFunc("/", indexHandler)
        if err := http.ListenAndServe(":8080", nil); err != nil {
                fmt.Fprintf(os.Stderr, "error: %s\n", err)
