Browsers don't have the require method defined, but Node.js does. With Browserify you can write code that uses require in the same way that you would use it in Node.
Here is a tutorial on how to use Browserify on the command line to bundle up a simple file called main.js along with all of its dependencies:
var unique = require('uniq');
var data = [1, 2, 2, 3, 4, 5, 5, 5, 6];
Install the uniq
module with npm
npm install uniq
Now recursively bundle up all the required modules starting at main.js into a single file called bundle.js with the browserify command:
browserify main.js -o bundle.js
Browserify parses the AST
calls to traverse the entire dependency graph of your project.

- Read the Browserify Handbook
Use many of the tens of thousands of modules on NPM in the browser
- Use watchify, a browserify compatible caching bundler, for super-fast bundle rebuilds as you develop.
- Use tinyify for optimized, tree-shaked bundles in production environments.
- Use --debug when creating bundles to have Browserify automatically include Source Maps for easy debugging.
- Check out tools like Beefy or run-browser which make automating browserify development easier.
