EventStream

EventStream is an open-source Node.js library that simplifies processing data through composable streams. It combines functional programming concepts with Node.js input and output operations. Developers can transform, filter, merge, split, and combine streams using reusable functions. Its API resembles familiar JavaScript array operations while processing values incrementally as they arrive. The library supports asynchronous transformations, line-oriented text processing, and stream-to-stream pipelines. It also provides utilities for converting event emitters and callbacks into streams. EventStream is useful for file processing, network operations, and data transformation workflows. The package experienced a significant supply chain compromise in 2018, making dependency version verification especially important.
