README

goembed

goembed takes a list of local files and embeds them into golang source files.

Compression

Supported compression algorithms:

• deflate
• gzip
• lzw
• snappy
• snappy (stream)
• zlib
• none

Wrappers

Supported wrappers:

• nodep No runtime dependencies, self-contained.
• afero using spf13/afero.

Usage

Install the command line tool first.

go get github.com/koshatul/goembed/cmd/...

goembed has sane defaults and will safely generate a go package from a directory or individual list of files.

$ goembed -f src/webasset/assets.go ./web

Then in your application just import the generated package

If you prefer to use a pseudo-filesystem there is support for using afero as a wrapper.

package main

import (
	"log"
	"net/http"

	"github.com/koshatul/goembed/examples/webserver/assets"
)

func main() {
	fileserver := http.FileServer(assets.Fs)
	http.Handle("/", http.StripPrefix("/", fileserver))
	log.Println("Listening on :8080")
	http.ListenAndServe(":8080", nil)
}

Then the filesystem should be visible from http://localhost:8080/
