I have a JavaScript library called web3js that is a back-end library and required by NodeJS. I need to apply web3js in the client side (HTML DOM), So I tried it by Browserify. I traversed all steps mentioned in Browserify guide sequencely. So, I tried these:

1. I just write this single-line code in NodeJS file:

   var Web3=require(web3);

That is the entire of NodeJS code.

2. npm install web3

3. browserify main.js -o bundle.js

main.js is the same NodeJS file that just has var Web3=require(web3);. After that, I included bundle.js in my DOM:

4. <script src="bundle.js"></script>

Now, I don't know how I should call and access web3js functions. What steps should I traverse to apply web3js there?
