It's my blogger article for http://programer-learn.blogspot.com/2015/03/reactjs-example-with-browserify-and.html

app.js

var React = require("react");  //use require(module_name) to load module.

React.render(
    <p>Hello, World!</p>,
    document.getElementById('hello')
);

build.sh

$ cd react-browserify-demo # go into project root folder
$ browserify -t reactify -t debowerify public/js/src/app.js -o public/js/build/build.js

ex1.js

var React = require('react');
// or
var flux = require('flux');

index.jade

extends layout
block content
  div(id="hello")
  script(src="/js/build/build.js")

init.sh

$ npm install browserify -g    #install browserify to your systems first. But you can just install in you project only
$ express react-browserify-demo
$ cd react-browserify-demo
$ npm install debowerify --save-dev
$ npm install reactify --save-dev
# before use bower, plz prepare your bower.json, following is a basic format
# {
#   "name": "react-browserify-demo",
#   "version": "0.1.0"
# }
$ bower install react --save  #Here I install react woth bower instead of npm
