# Transform Stream-like
> Test if a value is Node [transform stream][nodejs-stream]-like.
## Usage
```javascript
var isNodeTransformStreamLike = require( '@stdlib/assert/is-node-transform-stream-like' );
```
#### isNodeTransformStreamLike( value )
Tests if a `value` is Node [transform stream][nodejs-stream]-like.
```javascript
var transformStream = require( '@stdlib/streams/node/transform' );
var bool = isNodeTransformStreamLike( transformStream() );
// returns true
```
## Examples
```javascript
var stream = require( 'stream' );
var transformStream = require( '@stdlib/streams/node/transform' );
var isNodeTransformStreamLike = require( '@stdlib/assert/is-node-transform-stream-like' );
var bool = isNodeTransformStreamLike( new stream.Transform() );
// returns true
bool = isNodeTransformStreamLike( transformStream() );
// returns true
bool = isNodeTransformStreamLike( new stream.Stream() );
// returns false
bool = isNodeTransformStreamLike( new stream.Readable() );
// returns false
bool = isNodeTransformStreamLike( new stream.Writable() );
// returns false
bool = isNodeTransformStreamLike( new stream.Duplex() );
// returns false
bool = isNodeTransformStreamLike( {} );
// returns false
bool = isNodeTransformStreamLike( [] );
// returns false
bool = isNodeTransformStreamLike( null );
// returns false
function Stream() {
return this;
}
bool = isNodeTransformStreamLike( Stream );
// returns false
bool = isNodeTransformStreamLike( new Stream() );
// returns false
```
