Web Stream Tools

Web Stream Tools (available as `@openpgp/web-stream-tools` on npm) is a JavaScript utility library designed to simplify working with WhatWG Streams. It provides a comprehensive set of functions for common stream operations, including reading to completion (`readToEnd`), concatenating streams (`concat`), slicing parts of streams (`slice`), cloning streams (`clone`), and facilitating conversion between Node.js streams and Web Streams (`webToNode`, `nodeToWeb`). The library also features advanced capabilities for transforming stream data, either directly (`transform`) or in chunks with backpressure handling (`transformPair`), and for parsing structured data from streams (`parse`) with functions like `readByte`, `readBytes`, and `readLine`. The current stable version is 0.3.0. Developed by the OpenPGP.js team, it maintains an active development status, with updates generally released as needed. A key differentiator is its explicit focus on the WhatWG Streams API, providing a consistent interface across browser and modern Node.js environments, streamlining complex stream manipulations that often involve manual reader/writer management.
