With stream 2+, this is equivalent to `stream.unpipe()`. When used with streams 1 style streams (typically Node.js 0.8 and below), this module attempts to undo the actions done in `stream.pipe(dest)`. ## License [MIT](LICENSE) [npm-image]: https://img.shields.io/npm/v/unpipe.svg [npm-url]: https://npmjs.org/package/unpipe [node-image]: https://img.shields.io/node/v/unpipe.svg [node-url]: http://nodejs.org/download/ [travis-image]: https://img.shields.io/travis/stream-utils/unpipe.svg [travis-url]: https://travis-ci.org/stream-utils/unpipe [coveralls-image]: https://img.shields.io/coveralls/stream-utils/unpipe.svg [coveralls-url]: https://coveralls.io/r/stream-utils/unpipe?branch=master [downloads-image]: https://img.shields.io/npm/dm/unpipe.svg [downloads-url]: https://npmjs.org/package/unpipe unpipe-1.0.0/index.js000066400000000000000000000021361253736164500144730ustar00rootroot00000000000000/*! * unpipe * Copyright(c) 2015 Douglas Christopher Wilson * MIT Licensed */ 'use strict' /** * Module exports. * @public */ module.exports = unpipe /** * Determine if there are Node.js pipe-like data listeners. * @private */ function hasPipeDataListeners(stream) { var listeners = stream.listeners('data') for (var i = 0;
