json-stream-stringify is a Node.js package that efficiently stringifies JavaScript objects and arrays into JSON streams. Ideal for handling large datasets where memory is a concern, it streams output, avoiding loading the entire JSON structure into memory at once. This makes it suitable for scenarios like creating large JSON files or serving JSON data through HTTP streams. The package offers options for formatting and filtering, providing control over the output, enhancing readability and minimizing the size of the streamed JSON.
