# 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.
