Determine if an object is a Buffer (including the browserify Buffer)

saucelabs

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 module in browserify).

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(Buffer.alloc(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
