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.

This module supports almost the whole memcached ascii protocol, and provides many more commands than the embedded memcached module in Nginx. The libnginx-mod-http-srcache-filter module can be configured to use that module to cache responses.

This library implements both server and client aspects of the WebSocket protocol, striving for safety, correctness, and ergonomics. It is based on the wsproto project, which is a Sans-IO state machine that implements the majority of the WebSocket protocol, including framing, codecs, and events. This library handles I/O using the Trio framework. This library passes the Autobahn Test Suite.

This module provides more directives that can be used in the Nginx rewrite phase, like the 'set' directive. - URI escaping and unescaping - JSON quoting - digests encoding and decoding - random number generator

This Python module provides tools for converting from the Spanish banks' format *CSB/AEB norm 43* to other file formats.
