Msgpack — @coderbuzz/msgpack

High-performance MessagePack serialization for TypeScript. 55% smaller than JSON for compact objects. Zero-copy encode. Buffer reuse. Pre-allocation.

Why @coderbuzz/msgpack?

• Reusable internal buffer — minimizes GC pressure across encode calls
• encodeUnsafe() — zero-copy, returns view of internal buffer
• encodeInto() — writes to caller-owned buffer (pre-allocation)
• encodedSize() — exact byte count without allocating
• Smart integer encoding — always selects smallest possible format
• Fast paths — inline UTF-8 for short strings, ASCII scan for <=24 bytes
• <3 KB gzip vs @msgpack/msgpack ~10 KB

Installation

npm install @coderbuzz/msgpack

Quick Start

import { decode, encode } from "@coderbuzz/msgpack";

const bytes = encode({ name: "Alice", age: 30, active: true });
// ~20 bytes vs ~45 bytes JSON

const value = decode(bytes);
// => { name: "Alice", age: 30, active: true }
