The proxy-protocol-parser is a Node.js module that provides encoding and decoding functionality for HAProxy's proxy protocol v1 and v2 formats, supporting IPv4, IPv6, TCP, and UDP connections. It's designed for developers working with load balancers, reverse proxies, or network infrastructure who need to parse or generate proxy protocol headers to preserve client connection information. The library offers separate functions for each protocol version and includes validation capabilities to ensure header integrity.
