First things first. I know that there are other questions that are similar to this e.g. use NodeJs Buffer class from client side or How can I use node.js buffer library in client side javascript

However, I don't understand how to make use of the reference to use browserify though it is given approval.

Here is my Node code:

import { Buffer } from 'buffer/';

I know this is the ES6 equivalent of require.

I would like a javaScript file implementation of this module so that I can simply use the standard html file reference:

<script src=./js/buffer.js></script>

And then use it as in for example

return new Buffer(temp).toString('utf-8');

This simply falls over with the

Uncaught ReferenceError: Buffer is not defined 

no matter how I create the buffer.js file.

So using the browserify idea I've tried using the standalone script (from the as /[email protected] )

I've created a test.js file and put

var Buffer = require('buffer/').Buffer 

in it and then run browserify on it as

browserify test.js -o buffer.js

and many other variations. I'm not getting anywhere. I know I must be doing something silly that reflects my ignorance. Maybe you can help educate me please.

These instructions worked for me. Cheers!

Here are the instructions you can look at the web section. https://github./feross/buffer

Here is what the instructions state about using it in the browser without browserify. So from what you tried

 browserify test.js -o buffer.js

I would just use the version directly that does not require browserify

To use this module directly (without browserify), install it:

npm install buffer

To depend on this module explicitly (without browserify), require it like this:

var Buffer = require('buffer/').Buffer // note: the trailing slash is important!
