+# isStream
+
+[](http://travis-ci.org/rvagg/isstream)
+
+**Test if an object is a `Stream`**
+
+[](https://nodei.co/npm/isstream/)
+
+The missing `Stream.isStream(obj)`: determine if an object is standard Node.js `Stream`. 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)**.
+
+## Usage:
+
+```js
+var isStream = require('isstream')
+var Stream = require('stream')
+
+isStream(new Stream()) // true
+
+isStream({}) // false
+
+isStream(new Stream.Readable()) // true
+isStream(new Stream.Writable()) // true
+isStream(new Stream.Duplex()) // true
+isStream(new Stream.Transform()) // true
+isStream(new Stream.PassThrough()) // true
+```
+
+## But wait! There's more!
+
+You can also test for `isReadable(obj)`, `isWritable(obj)` and `isDuplex(obj)` to test for implementations of Streams2 (and Streams3) base classes.
+
+```js
+var isReadable = require('isstream').isReadable
+var isWritable = require('isstream').isWritable
+var isDuplex = require('isstream').isDuplex
+var Stream = require('stream')
+
+isReadable(new Stream()) // false
+isWritable(new Stream()) // false
+isDuplex(new Stream()) // false
+
+isReadable(new Stream.Readable()) // true
+isReadable(new Stream.Writable()) // false
+isReadable(new Stream.Duplex()) // true
+isReadable(new Stream.Transform()) // true
+isReadable(new Stream.PassThrough()) // true
+
+isWritable(new Stream.Readable()) // false
+isWritable(new Stream.Writable()) // true
+isWritable(new Stream.Duplex()) // true
+isWritable(new Stream.Transform()) // true
+isWritable(new Stream.PassThrough()) // true
+
+isDuplex(new Stream.Readable()) // false
+isDuplex(new Stream.Writable()) // false
+isDuplex(new Stream.Duplex()) // true
+isDuplex(new Stream.Transform()) // true
+isDuplex(new Stream.PassThrough()) // true
+```
+
+*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).*
