## What it is
A Ruby gem providing C bindings to the YAJL library for streaming JSON parsing and encoding. It supports parsing directly from IO streams (files, sockets, compressed streams) and offers a drop-in replacement API for the standard JSON gem with significantly better performance.

## Use cases
- parse large JSON files without loading them fully into memory
- stream-parse multiple JSON objects from a socket or HTTP response
- replace the Ruby JSON gem with a faster drop-in alternative
- parse gzip or bzip2 compressed JSON streams
- incrementally feed JSON chunks to a parser in an evented server
- encode Ruby objects to JSON faster than JSON.generate

## When to avoid
- you only need simple, occasional JSON parsing where the stdlib JSON gem suffices
- you need a pure-Ruby solution without native C extensions
- your project no longer uses Ruby

## Facets
- artifact type: library
- maturity: maintenance
- function: serialization, parser, http-client
- domain: developer-tools, apis
- platform: ruby, cross-platform
- tags: json, streaming, c-extension, ruby-gem, performance, data-engineering
