Superjson | Awesome Repository

Superjson is a lossless JSON serialization library and data transcoder. It converts complex JavaScript and TypeScript data types into strings and metadata to ensure that type identity is preserved during data transfer.

The library preserves non-native types such as Dates, Maps, and Sets by splitting values into a JSON-compatible payload and a separate map of type-specific metadata. It utilizes a registry-based mapping system that allows for the definition of custom type handlers to manage third-party data types during serialization and deserialization.

This utility supports cross-process data communication and type-safe data transfer by restoring original object prototypes and complex data types. It performs encoding based on runtime types rather than using a predefined schema.

Features

Lossless - Implements a lossless transcoding mechanism to preserve non-native types like Dates, Maps, and Sets during transport.
Type Fidelity Preservation - Implements lossless serialization that preserves complex JavaScript types like Maps and Sets.
Complex Data Serialization - Converts non-standard types into a compatible string and metadata pair for lossless transport.
Complex Data Type Exchange - Restores complex data types from strings and metadata to maintain type fidelity after transfer.
