When this `-compressed` directory is passed to a properly configured web
|
||||
server, it will serve those pre-compressed files:
|
||||
|
||||
$ curl -I -H 'Accept-Encoding: br' https://irc.example.org/
|
||||
<...>
|
||||
content-encoding: br
|
||||
<...>
|
||||
|
||||
For example, a caddy configuration snippet for gamja to serve
|
||||
the static assets (JS, CSS files) pre-compressed:
|
||||
|
||||
virtualHosts."irc.example.org".extraConfig = ''
|
||||
root * ${pkgs.compressAll pkgs.gamja {}}
|
||||
file_server browse {
|
||||
precompressed br gzip
|
||||
}
|
||||
'';
|
||||
|
||||
This feature is also available in nginx via `ngx_brotli` and
|
||||
`ngx_http_gzip_static_module`.
|
||||
|
||||
|
||||
Inputs:
|
||||
- formats :: [String]
|
||||
|
||||
The default list of file extensions to compress.
|
||||
|
||||
Default: common formats that compress well. The list may be appended (but
|
||||
not reduced) without warning.
|
||||
|
||||
- extraFormats :: [String]
|
||||
|
||||
Extra extensions to compress in addition to `extensions`.
|
||||
|
||||
- compressors :: [String]
|
||||
|
||||
A list of compressor names to use.
|
||||
|
||||
Default: ["gz" "br"]
|
||||
|
||||
- compressor-<COMPRESSOR> :: String
|
||||
|
||||
Maps a desired extension (e.g. `gz`) to a compress program (e.g. `zopfli
|
||||
--keep {}`).
|
||||
|
||||
The compressor program that will be executed to get the `COMPRESSOR`
|
||||
extension. The program is passed to xargs like this:
|
||||
|
||||
xargs -I{} -n1 ${prog}
|
||||
|
||||
Example:
|
||||
|
||||
compressor-xz = "${xz}/bin/xz --keep {}";
|
||||
compressor-zst = "${zstd}/bin/zstd --keep {}";
