Streaming Environment Variable Parser

env-parser (digitalsadhu/env-parser) is a streaming transform module designed to parse individual `key=value` pairs from a stream and emit JavaScript objects. It processes data by splitting on the first equals sign (`=`) and automatically removes quotation marks from values if present. As of version 1.0.1, last published in June 2015, this package appears to be unmaintained. Its primary use case is for integrating into Node.js stream pipelines where environment variable-like strings are being processed sequentially, rather than for parsing complete `.env` files. There are no indications of active development or a release cadence, and newer, more comprehensive environment variable parsing libraries are widely available.
