Install with npm:

$ npm install --save is-binary-buffer
This a node.js library written in pure javascript that can be used to check if the given value is a "binary buffer".
You can add this library to your node.js application using node's require() system with the following line of code:
`js
var fs = require('fs');
var isBinary = require('is-binary-buffer');
console.log(isBinary('foo'));
console.log(isBinary(new Buffer('foo')));
//=> false
console.log(isBinary(fs.readFileSync('some-image.jpg')));
console.log(isBinary(fs.readFileSync('some-image.gif')));
//=> true
`
Based on the code from isbinaryfile, which only reads from the file system. If the file doesn't exist, is a directory, or is empty, the function returns false.
