pako - high speed zlib port to javascript, works in browser & node.js

•    Javascript

zlib's test is partially affected by marshalling (that make sense for inflate only). You can change deflate level to 0 in benchmark source, to investigate details. For deflate level 6 results can be considered as correct.

needle - Nimble, streamable HTTP client for Node

•    Javascript

The leanest and most handsome HTTP client in the Nodelands. Callbacks not floating your boat? Needle got your back.

compression - Node.js compression middleware

•    Javascript

Node.js compression middleware. Returns the compression middleware using the given options. The middleware will attempt to compress response bodies for all request that traverse through the middleware, based on the given options.

JSZip - Create, read and edit .zip files with Javascript

•    Javascript

A library for creating, reading and editing .zip files with JavaScript, with a lovely and simple API.

Zopfli - Compression library from Google

•    C++

Zopfli Compression Algorithm is a compression library programmed in C to perform very good, but slow, deflate or zlib compression. The basic function to compress data is ZopfliCompress in zopfli.h. Use the ZopfliOptions object to set parameters that affect the speed and compression. Use the ZopfliInitOptions function to place the default values in the ZopfliOptions first.

Snappy - Port of Snappy to Java

•    Java

This is a rewrite (port) of Snappy writen in pure Java. This compression code produces a byte-for-byte exact copy of the output created by the original C++ code, and extremely fast.

Snappy Java - Snappy compressor/decompressor for Java

•    Java

snappy-java is a Java port of the snappy, a fast C++ compresser/decompresser developed by Google. It does fast compression/decompression around 200~400MB/sec, Less memory usage. SnappyOutputStream uses only 32KB+ in default, Compression/decompression of Java primitive arrays (float[], double[], int[], short[], long[], etc.) and lot more.

LZF Compressor- High-performance, streaming/chunking Java LZF codec, compatible with standard C LZF package

•    Java

LZF-compress is a Java library for encoding and decoding data in LZF format, written by Tatu Saloranta. LZF alfgorithm itself is optimized for speed, with somewhat more modest compression. Compared to the standard Deflate (algorithm gzip uses) LZF can be 5-6 times as fast to compress, and twice as fast to decompress. Compression rate is lower since no Huffman-encoding is used after lempel-ziv substring elimintation.

zlib-ng - zlib replacement with optimizations for "next generation" systems.

•    C

The motivation for this fork was due to seeing several 3rd party contributions containing new optimizations not getting implemented into the official zlib repository. Mark Adler has been maintaining zlib for a very long time, and he has done a great job and hopefully he will continue for a long time yet. The idea of zlib-ng is not to replace zlib, but to co-exist as a drop-in replacement with a lower threshold for code change.

flate2-rs - DEFLATE, gzip, and zlib bindings for Rust

•    C

A streaming compression/decompression library DEFLATE-based streams in Rust. This crate by default uses the miniz_oxide crate, a port of miniz.c to pure Rust. This crate also supports other backends, such as the widely available zlib library or the high-performance zlib-ng library.

ZipStorer - A Pure C# Class to Store Files in Zip

•    DotNet

Small C# class to store and extract uncompressed and deflated files in new or existing Zip files, without any external library. Works with .net 2.0 and up, and Compact Framework.

HTTP Compression Library for Heavy Load Web Server

Deflater is a HTTP Compression Library, supporting Deflate (RFC 1950, RFC 1951) and GZip (RFC 1952). It is designed to encode and compress HTML content at once.

DeflateLib

The implementation of RFC 1951 -- DEFLATE Compressed Data Format Specification version 1.3 (also RFC 1950 ZLIB and 1952 GZIP). It's written in managed C#. The project has basic compression algorithm implementation as it's described in the RFC.

simple-get - Simplest way to make http get requests

•    Javascript

Simplest way to make http get requests. Supports HTTPS, redirects, gzip/deflate, streams in < 100 lines.

oppressor - streaming http compression response negotiator

•    Javascript

Return a duplex stream that will be compressed with gzip, deflate, or no compression depending on the accept-encoding headers sent.oppressor will emulate calls to http.ServerResponse methods like writeHead() so that modules like filed that expect to be piped directly to the response object will work.

minizlib - A smaller, faster, zlib stream built on http://npm

•    Javascript

A tiny fast zlib stream built on minipass and Node.js's zlib binding.This module was created to serve the needs of node-tar v2. If your needs are different, then it may not be for you.

decompress-response - Decompress a HTTP response if needed

•    Javascript

Decompresses the response from http.request if it's gzipped or deflated, otherwise just passes it through.Used by got.

tiny-cdn - A tiny static files serving handler

•    Javascript

This module has been developed on top of holdon utility. While this script is the fastest on Internet of Things devices such Arduino Yun or Raspberry PI, it has also been tested on regular servers and it has demonstrated to be both reliable and on average 2X or more faster than common nodejs solutions.
