## Why not use `Buffer.isBuffer`?
|
||
|
|
|
||
|
|
This module lets you check if an object is a `Buffer` without using `Buffer.isBuffer` (which includes the whole [buffer](https://github.com/feross/buffer) module in [browserify](http://browserify.org/)).
|
||
|
|
|
||
|
|
It's future-proof and works in node too!

|
## install
|
||
|
|
|
||
|
|
```bash
|
||
|
|
npm install is-buffer
|
||
|
|
```
|
||
|
|
|
||
|
|
## usage
|
||
|
|
|
||
|
|
```js
|
||
|
|
var isBuffer = require('is-buffer')
|
||
|
|
|
||
|
|
isBuffer(new Buffer(4)) // true
|
||
|
|
|
||
|
|
isBuffer(undefined) // false
|
||
|
|
isBuffer(null) // false
|
||
|
|
isBuffer('') // false
|
||
|
|
isBuffer(true) // false
|
||
|
|
isBuffer(false) // false
|
||
|
|
isBuffer(0) // false
|
||
|
|
isBuffer(1) // false
|
||
|
|
isBuffer(1.0) // false
|
||
|
|
isBuffer('string') // false
|
||
|
|
isBuffer({}) // false
|
||
|
|
isBuffer(function foo () {}) // false
|
||
|
|
```
