stream-transform is a Node.js package designed for transforming streams of data. It simplifies processing data in a streaming fashion, allowing you to apply transformations to each chunk or record as it passes through. This is especially useful when dealing with large datasets or continuous data feeds. Features include flexible transformation functions, error handling, and asynchronous operations, empowering you to efficiently manipulate data streams without loading everything into memory at once. Use cases range from data cleansing to format conversion within streaming pipelines.
