msgpack-lite

msgpack-lite is a pure JavaScript implementation of the MessagePack serialization format, providing fast encoding and decoding capabilities for both Node.js and web browsers. As of version 0.1.26, it offers synchronous `encode` and `decode` functions, along with streaming interfaces via `createEncodeStream` and `createDecodeStream`. It differentiated itself by claiming performance superior to some C++ MessagePack libraries for Node.js v4, without requiring native C++ compilation (node-gyp). The library supports various input types for decoding, including Node.js `Buffer`, standard JavaScript `Array`, and `Uint8Array`. It was tested on older Node.js versions (v0.10 through v6) and a wide range of browsers, including IE8. The last release was over 8 years ago, indicating it is no longer actively maintained.
