Takes a buffer and does not read from the file system.\n\nPlease consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.\n\n## Install\n\nInstall with [npm](https://www.npmjs.com/):\n\n```sh\n$ npm install --save is-binary-buffer\n```\n\n## What is this?\n\nThis a node.js library written in pure javascript that can be used to check if the given value is a \"binary buffer\".\n\n## Usage\n\nYou can add this library to your node.js application using node's `require()` system with the following line of code:\n\n```js\nvar fs = require('fs');\nvar isBinary = require('is-binary-buffer');\n\nconsole.log(isBinary('foo'));             \nconsole.log(isBinary(new Buffer('foo'))); \n//=\u003e false\n\nconsole.log(isBinary(fs.readFileSync('some-image.jpg'))); \nconsole.log(isBinary(fs.readFileSync('some-image.gif'))); \n//=\u003e true\n```\n\n## Attribution\n\nBased on the code from [isbinaryfile](https://github.com/gjtorikian/isBinaryFile), which only reads from the file system. If the file doesn't exist, is a directory, or is empty, the function returns false.\n\n[isbinaryfile is MIT Licensed](https://github.com/gjtorikian/isBinaryFile/blob/b808cba3faa824bd3cade089743a714187af7193/LICENSE.txt)\n\n## About\n\n\u003cdetails\u003e\n\u003csummary\u003e\u003cstrong\u003eContributing\u003c/strong\u003e\u003c/summary\u003e\n\nPull requests and stars are always welcome.
