Meteor ReferenceError Buffer is not defined

I'm running Meteor 1.4.2.3 and after adding some code that deals with files I get a reference error saying "Buffer" is not defined.

The error is in util.js

exports.isPrimitive = isPrimitive; exports.isBuffer = Buffer.isBuffer;

Uncaught ReferenceError: Buffer is not defined

What is the dependency for Buffer ? am I missing a package?

Adding this code on Startup worked for me

 global.Buffer = function() {}
 global.Buffer.isBuffer = () => false

Complete Code looks like this

Meteor.startup(()=> {
  global.Buffer = function() {}
  global.Buffer.isBuffer = () => false
  ReactDOM.render(<App />, document.getElementById('container'));
});

Buffer is a builtin class in Node.js and doesn't exist in browsers. If there is a separate browser compatible version of the dependency try using that one instead. If not, there is a package in NPM called buffer that can be used as a polyfill in browsers, React Native and other non-Node.js environments.

import Buffer from 'buffer';

if (typeof this.Buffer === 'undefined') {
  this.Buffer = Buffer.Buffer;
}
