> Validates if a value is a [Buffer][node-buffer] object.


## Installation

``` bash
$ npm install validate.io-buffer
```


## Usage

``` javascript
var isBuffer = require( 'validate.io-buffer' );
```

#### isBuffer( value )

Validates if a `value` is a [`Buffer`][node-buffer] object.

``` javascript
var value = new Buffer( [1,2,3,4] );

var bool = isBuffer( value );
// returns true
```


## Notes

* 	Validates both [Node.js][node-buffer] and [browser][browser-buffer] (polyfill) `Buffer` objects.


## Examples

``` javascript
var isBuffer = require( 'validate.io-buffer' );

console.log( isBuffer( new Buffer( [1,2,3,4] ) ) );
// returns true

console.log( isBuffer( new Buffer( 'beep' ) ) );
// returns true

console.log( isBuffer( [] ) );
// returns false
```

To run the example code from the top-level application directory,

``` bash
$ node ./examples/index.js
```

## Tests

### Unit

This repository uses [tape][tape] for unit tests. To run the tests, execute the following command in the top-level application directory:

``` bash
$ make test
```

All new feature development should have corresponding unit tests to validate correct functionality.


### Test Coverage

This repository uses [Istanbul][istanbul] as its code coverage tool. To generate a test coverage report, execute the following command in the top-level application directory:

``` bash
$ make test-cov
```

Istanbul creates a `./reports/coverage` directory. To access an HTML version of the report,

``` bash
$ make view-cov
```


### Browser Support

This repository uses [Testling][testling] for browser testing. To run the tests in a (headless) local web browser, execute the following command in the top-level application directory:

``` bash
$ make test-browsers
```

To view the tests in a local web browser,

``` bash
$ make view-browser-tests
```
