kriszyp/cbor-x

This is a high-performance CBOR (Concise Binary Object Representation) encoder/decoder for JavaScript and Node.js. It offers extremely fast serialization and deserialization speeds, often outperforming native JSON functions and other CBOR libraries. The library supports standard CBOR encoding, as well as extensions for records and structural cloning, making it ideal for applications requiring efficient data storage, transmission, or processing. It is particularly useful for developers working with large datasets, streaming data, or those needing to preserve object structures and types during serialization.
