peechy

peechy is a schema-based binary serialization format for efficiently encoding trees of data. It is designed for high performance and compact encoding of complex nested structures. Version 0.4.310 is actively developed. Unlike Protocol Buffers or FlatBuffers, peechy focuses on encoding trees with minimal overhead and supports JavaScript/TypeScript natively. It uses a schema definition language and generates efficient encoders/decoders. The package ships TypeScript types and is intended for Node.js and browser environments where binary size and speed are critical.
