LDJSON Stream Parser & Serializer

ldjson-stream is a streaming library designed for parsing and serializing line-delimited JSON (also known as NDJSON or JSON Lines). It provides two primary Transform streams: `parse()` for converting newline-separated JSON strings into JavaScript objects, and `serialize()` for converting JavaScript objects into newline-delimited JSON strings. The package is lightweight and was last updated over a decade ago, with its current stable version being 1.2.1. Due to its age, it exclusively uses CommonJS modules and does not offer native ESM support or TypeScript type definitions. While it remains functional for basic NDJSON processing in older Node.js environments, its abandoned status means it lacks ongoing maintenance, security updates, or compatibility enhancements for modern JavaScript ecosystems. It was a minimalist solution for streaming JSON in its time.
