jsontuki

JSONtuki is an open-source software library that provides tools for working with JSON data in JavaScript environments. It emphasizes fast parsing, validation, and transformation, with support for streaming to handle large documents without loading them entirely into memory. The library is designed to run in both Node.js and web browsers, making it suitable for server-side data processing as well as client-side data handling.

Key features include a streaming JSON parser, schema-based validation compatible with JSON Schema rules, and transformation pipelines that allow applying a sequence of operations as data is parsed. It provides detailed error reporting with position information to aid debugging in streaming contexts. The modular design separates the core parsing engine from validation and transformation plugins, enabling customization and extension.

JSONtuki is released under an open-source license and follows semantic versioning to communicate compatibility and changes. The project typically distributes via standard package managers, with installation example: npm install jsontuki, then import or require the library in applications. It supports incremental parsing, backpressure-aware streams, and adapters for common runtimes, including Node.js streams and browser ReadableStream instances.

In practice, JSONtuki is used in data ingestion pipelines, API servers, and web applications that need robust, memory-efficient JSON handling. It aims to provide a consistent API for parsing, validating, and transforming JSON data across environments, reducing boilerplate and improving error reporting in streaming scenarios.
