About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

Duplex Stream-like

Test if a value is Node duplex stream-like.

Installation

1npm install @stdlib/assert-is-node-duplex-stream-like

Usage

1var isNodeDuplexStreamLike = require( '@stdlib/assert-is-node-duplex-stream-like' );

isNodeDuplexStreamLike( value )

Tests if a value is Node duplex stream-like.

1var transformStream = require( '@stdlib/streams-node-transform' );
2
3var bool = isNodeDuplexStreamLike( transformStream() );
4// returns true

Examples

1var stream = require( 'stream' );
2var transformStream = require( '@stdlib/streams-node-transform' );
3var isNodeDuplexStreamLike = require( '@stdlib/assert-is-node-duplex-stream-like' );
4
5var bool = isNodeDuplexStreamLike( new stream.Duplex() );
6// returns true
7
8bool = isNodeDuplexStreamLike( new stream.Transform() );
9// returns true
10
11bool = isNodeDuplexStreamLike( transformStream() );
12// returns true
13
14bool = isNodeDuplexStreamLike( new stream.Writable() );
15// returns false
16
17bool = isNodeDuplexStreamLike( new stream.Readable() );
18// returns false
19
20bool = isNodeDuplexStreamLike( new stream.Stream() );
21// returns false
22
23bool = isNodeDuplexStreamLike( {} );
24// returns false
25
26bool = isNodeDuplexStreamLike( [] );
27// returns false
28
29bool = isNodeDuplexStreamLike( null );
30// returns false
31
32function Stream() {
33    return this;
34}
35
36bool = isNodeDuplexStreamLike( Stream );
37// returns false
38
39bool = isNodeDuplexStreamLike( new Stream() );
40// returns false

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
