CallbackStream is a Node.js library that provides a pipeable stream which calls a callback with an array of data when the stream ends. It is designed as a safe alternative to concat-stream, ensuring the data is always returned as an array, and supports both Stream 2 and Stream 3 APIs. This tool is ideal for developers working with Node.js streams who need a reliable way to handle streamed data in array format.
