Nodeify: Promise to Node Callback Converter

Nodeify is a compact utility designed to convert Promise/A+-compliant promises into Node.js-style callback invocations. It allows developers to seamlessly integrate promise-based asynchronous operations into existing callback-driven codebases. The package offers several usage patterns: a direct functional approach, a `nodeify.Promise` constructor that returns promises with a `.nodeify` method, and various `extend` methods to add the `.nodeify` method to existing promise constructors or instances. The current stable version is 1.0.1. Due to its last publish date over seven years ago and no recent activity, the package is considered abandoned. For modern Node.js development, built-in features like `util.promisify` or native `async/await` are the preferred and more robust solutions for handling asynchronous operations and bridging between promises and callbacks.
