# gzipped.FileServer
Drop-in replacement for golang http.FileServer which supports static content
compressed with gzip (including zopfli) or brotli.
This allows major bandwidth savings for CSS, JavaScript libraries, fonts, and
other static compressible web content. It also means you can compress the
content without significant runtime penalty.
## Example
Suppose `/var/www/assets/css` contains your style sheets, and you want to make them available as `/css/*.css`:
package main
import (
"log"
"net/http"
"github.com/lpar/gzipped"
)
func main() {
log.Fatal(http.ListenAndServe(":8080", http.StripPrefix("/css",
gzipped.FileServer(http.Dir("/var/www/assets/css")))))
}
// curl localhost:8080/css/styles.css
Using [httprouter](https://github.com/julienschmidt/httprouter)?
router := httprouter.New()
router.Handler("GET", "/css/*filepath",
gzipped.FileServer(http.Dir("/var/www/assets/css"))))
log.Fatal(http.ListenAndServe(":8080", router)
## Detail
For any given request at `/path/filename.ext`, if:
1. There exists a file named `/path/filename.ext.(gz|br)` (starting from the
appropriate base directory), and
2. the client will accept content compressed via the appropriate algorithm, and
3. the file can be opened,
then the compressed file will be served as `/path/filename.ext`, with a
`Content-Encoding` header set so that the client transparently decompresses it.
Otherwise, the request is passed through and handled unchanged.
Unlike other similar code I found, this package has a license, parses
Accept-Encoding headers properly, and has unit tests.
## Caveats
All requests are passed to Go's standard `http.ServeContent` method for
fulfilment. MIME type sniffing, accept ranges, content negotiation and other
tricky details are handled by that method.
It is up to you to ensure that your compressed and uncompressed resources are
kept in sync.
Directory browsing isn't supported. (You probably don't want it on your
application anyway, and if you do then you probably don't want Go's default
implementation.)
## Related
* You might consider precompressing your CSS with [minify](https://github.com/tdewolff/minify).
* If you want to get the best possible compression for clients which don't support brotli, use [zopfli](https://github.com/google/zopfli).
* To compress your dynamically-generated HTML pages on the fly, I suggest [gziphandler](https://github.com/NYTimes/gziphandler).
