holepunchto/compact-encoding

compact‑encoding is a Node.js library that provides a collection of tiny, high‑performance binary encoders/decoders (e.g., var‑int, fixed‑size ints, floats, strings, buffers, arrays, IP addresses, dates, JSON, etc.). It lets developers quickly pre‑compute buffer sizes, then encode or decode values with a simple state‑object API, making it ideal for building fast, space‑efficient parsers and serializers in any JavaScript project.
