# go-bindata-assetfs
Serve embedded files from [jteeuwen/go-bindata](https://github.com/jteeuwen/go-bindata) with `net/http`.
[GoDoc](http://godoc.org/github.com/elazarl/go-bindata-assetfs)
### Installation
Install with
$ go get github.com/jteeuwen/go-bindata/...
$ go get github.com/elazarl/go-bindata-assetfs/...
### Creating embedded data
Usage is identical to [jteeuwen/go-bindata](https://github.com/jteeuwen/go-bindata) usage,
instead of running `go-bindata` run `go-bindata-assetfs`.
The tool will create a `bindata_assetfs.go` file, which contains the embedded data.
A typical use case is
$ go-bindata-assetfs data/...
### Using assetFS in your code
The generated file provides an `assetFS()` function that returns a `http.Filesystem`
wrapping the embedded files. What you usually want to do is:
http.Handle("/", http.FileServer(assetFS()))
This would run an HTTP server serving the embedded files.
## Without running binary tool
You can always just run the `go-bindata` tool, and then
use
import "github.com/elazarl/go-bindata-assetfs"
...
http.Handle("/",
http.FileServer(
&assetfs.AssetFS{Asset: Asset, AssetDir: AssetDir, Prefix: "data"}))
to serve files embedded from the `data` directory.
