About:
LsHpack is a C library implementing the HPACK compression format as defined in the HTTP/2 specification (RFC 7541). It provides efficient encoding and decoding of HTTP header fields to reduce overhead and improve performance in HTTP/2 communications. Its main value is offering a robust, standalone compression component for servers, clients, and proxies implementing HTTP/2.

Key Features:

Implements RFC 7541 HPACK compression
Written in C for high performance and portability
Standalone library with minimal dependencies
Provides both encoding and decoding functionality
Designed for integration into HTTP/2 stacks

Use Cases:

Building or extending an HTTP/2 server or client
Adding HPACK compression support to a web proxy
Educational reference for HTTP/2 header compression implementation

Alternatives:

nghttp2 – Full-featured HTTP/2 library including HPACK, whereas ls-hpack is a focused HPACK-only component.
h2o – Optimized HTTP server with built-in HPACK; ls-hpack is a library for custom integration.
