is-buffer

is-buffer

Determine if an object is a Buffer (incl. browser buffers).

Why not use Buffer.isBuffer?

If you just want to check if an object is a Buffer without require('buffer') (which bundles the entire buffer module in browserify), then use this module. It's future-proof and works in node too!

install

npm install is-buffer

usage

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

buffer

The 'buffer' package is a Node.js Buffer implementation for the browser. It's more complex than is-buffer as it aims to provide the entire Buffer API in environments that do not have it natively. Unlike is-buffer, which only checks if an object is a Buffer, the 'buffer' package allows you to create and manipulate Buffer objects in the browser.
