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.

Installing

go get bitbucket.org/tebeka/nrsc
go get bitbucket.org/tebeka/nrsc/nrsc

(The 2’nd command will grab the nrsc executable)

And you’ll need zip somewhere in your path.

Invocation

go build
nrsc <executable> <resource dir> [zip options]

API

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.

Resource Interface

func Open() (io.Reader, error)

Returns a reader to resource data

func Size() int64

Returns resource size (to be used with Content-Length HTTP header).

func ModTime() time.Time

Returns modification time (to be used with Last-Modified HTTP header).

Example Code

package main

import (
        "fmt"
        "net/http"
        "os"

        "bitbucket.org/tebeka/nrsc"
)

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

func main() {
        nrsc.Handle("/static/")
        http.HandleFunc("/", indexHandler)
        if err := http.ListenAndServe(":8080", nil); err != nil {
                fmt.Fprintf(os.Stderr, "error: %s\n", err)
                os.Exit(1)
        }
}
