HSkódJSON

HSkódJSON is a software library for working with JSON data. It focuses on high‑performance parsing and serialization while providing schema‑aware validation, customizable encoders and decoders, and support for streaming data. The library is designed to be language‑agnostic, with bindings to multiple ecosystems and a pluggable backend architecture.

The core implementation emphasizes safety and speed, with the core written in a systems language and bindings to popular languages. It offers both strict mode, which adheres to the RFC 8259 specification, and permissive mode for common extensions. A streaming API enables incremental parsing and generation without loading entire documents into memory.

Key features include incremental parsing, memory efficient streaming, JSON Schema compatibility for validation, and extensible encoding/decoding hooks for dates, custom types, and user‑defined objects. Error reporting is designed to be actionable, including a path to the failing value and contextual information to ease debugging.

HSkódJSON originated as a collaborative open‑source project and has grown through community contributions and governance. It emphasizes cross‑language interoperability and compatibility with existing JSON tooling.

The library is used in data processing pipelines, web services, and client applications that require reliable JSON handling with validation and streaming support.
