Express JSON Prettifier Middleware

express-prettify is an Express.js middleware designed to automatically format (pretty-print) JSON responses based on the presence of a specified query parameter in the request URL. This enables developers to easily get human-readable API output for debugging or inspection by adding, for instance, `?pretty` to their requests, while standard minified JSON is returned otherwise. The current stable version is 0.1.2. However, the package has not seen significant updates since 2018, indicating an effectively abandoned status. It differentiates itself by offering a simple, client-controlled mechanism for JSON formatting without requiring server-side changes to every `res.json()` call or a global configuration.
