Stringify-object is a Node.js package that converts JavaScript objects into readable, single-line strings. It preserves object structure and data types, making debugging and logging easier. Unlike JSON.stringify, it produces cleaner output with quoted keys and supports circular references. You can configure options like indent size and quote style to tailor the output format to your needs for enhanced readability. It is useful for logging, debugging, and testing where clear and concise object representation is necessary.
