Browserify hello world

Browserify hello world example that exports a function for both browser and Node.js usage.

Basically answering: https://stackoverflow.com/questions/23296094/browserify-how-to-call-function-bundled-in-a-file-generated-through-browserify

Node.js development usage:

git clone https://github.com/cirosantilli/browserify-hello-world
cd browserify-hello-world
npm link
npm link browserify-hello-world
./browserify-hello-world

Output:

1 2 3

Here, ./browserify-hello-world is a Node.js executable, and it sees our browserify_hello_world.myfunc function and calls it.

Node.js usage from NPM:

npm install browserify-hello-world
npx browserify-hello-world

Browser usage:

npm run b

This runs:

npx browserify --outfile out.js --standalone browserify_hello_world index.js

which creates the file out.js, which is used in the index.html example with:

<script src="out.js"></script>

You can observe it:

xdg-open index.html

That page contains 1 2 3, which was also generated by our browserify-hello-world code just like the Node.js call.

As you can see, the cool thing about Browserify is that it recursively packs up all Node.js dependencies into the browser version of the JavaScript. Here as an example we imported the uniq library both on Node.js and browser.
