Brotli is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression.
ngx_brotli is a set of two nginx modules:
Both Brotli library and nginx module are under active development.
$ cd nginx-1.x.x $ ./configure --add-module=/path/to/ngx_brotli $ make && make install
ngx_brotli filter module depends on libbrotli, which must be installed on the target system for it to work.
Alternatively, ngx_brotli static module can be compiled into nginx by itself with
NGX_BROTLI_STATIC_MODULE_ONLY=1 defined in the environment:
$ cd nginx-1.x.x $ export NGX_BROTLI_STATIC_MODULE_ONLY=1 $ ./configure --add-module=/path/to/ngx_brotli $ make && make install
Enables or disables checking of the existence of pre-compressed files with
.br extension. With the
always value, pre-compressed file is used in all cases, without checking if the client supports it.
Enables or disables on-the-fly compression of responses.
brotli_types <mime_type> [..]
Enables on-the-fly compression of responses for the specified MIME types in addition to
text/html. The special value
* matches any MIME type. Responses with the
text/html MIME type are always compressed.
brotli_buffers <number> <size>
32 4k|16 8k
size of buffers used to compress a response. By default, the buffer size is equal to one memory page. This is either
8k, depending on a platform.

Achieved compression ratio, computed as the ratio between the original and compressed response sizes.
