Works for Node-core `Stream` objects (for 0.8, 0.10, 0.11, and in theory, older and newer versions) and all versions of **[readable-stream](https://github.com/isaacs/readable-stream)**.\n\n## Usage:\n\n```js\nvar isStream = require('isstream')\nvar Stream = require('stream')\n\nisStream(new Stream()) // true\n\nisStream({}) // false\n\nisStream(new Stream.Readable()) // true\nisStream(new Stream.Writable()) // true\nisStream(new Stream.Duplex()) // true\nisStream(new Stream.Transform()) // true\nisStream(new Stream.PassThrough()) // true\n```\n\n## But wait! There's more!\n\nYou can also test for `isReadable(obj)`, `isWritable(obj)` and `isDuplex(obj)` to test for implementations of Streams2 (and Streams3) base classes.\n\n```js\nvar isReadable = require('isstream').isReadable\nvar isWritable = require('isstream').isWritable\nvar isDuplex = require('isstream').isDuplex\nvar Stream = require('stream')\n\nisReadable(new Stream()) // false\nisWritable(new Stream()) // false\nisDuplex(new Stream()) // false\n\nisReadable(new Stream.Readable()) // true\nisReadable(new Stream.Writable()) // false\nisReadable(new Stream.Duplex()) // true\nisReadable(new Stream.Transform()) // true\nisReadable(new Stream.PassThrough()) // true\n\nisWritable(new Stream.Readable()) // false\nisWritable(new Stream.Writable()) // true\nisWritable(new Stream.Duplex()) // true\nisWritable(new Stream.Transform()) // true\nisWritable(new Stream.PassThrough()) // true\n\nisDuplex(new Stream.Readable()) // false\nisDuplex(new Stream.Writable()) // false\nisDuplex(new Stream.Duplex()) // true\nisDuplex(new Stream.Transform()) // true\nisDuplex(new Stream.PassThrough()) // true\n```\n\n*Reminder: when implementing your own streams, please [use **readable-stream** rather than core streams](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).*\n\n\n## License\n\n**isStream** is Copyright (c) 2015 Rod Vagg [@rvagg](https://twitter.com/rvagg) and licenced under the MIT licence.
