Trying to do common + page pattern. How do I build this with the API? https://github.com/substack/node-browserify#methods

build.js

#!/usr/bin/env node
var browserify = require('browserify');
var bowerResolve = require('bower-resolve');

// shared / common
bowerResolve.init(function(){
  var bCfg = {
    basedir: '/path/to/repo',
    noParse: [bowerResolve('jquery')]
  };
  var writestream = require('fs').createWriteStream('./src/main/resources/static/js/common.js');
  browserify(bCfg)
    .require(bowerResolve('jquery'), { expose: 'jquery' })
    .require(bowerResolve('flight', {expose: 'flight'}))
    .add('./src/main/js/common.js')
    .transform('deamdify')
    .transform('debowerify')
    .bundle()
    .pipe(writestream);

  //  about (logged-out)
  var writestream = require('fs').createWriteStream('./src/main/resources/static/js/about.js');
  browserify(bCfg)
    .external('jquery')
    .external('flight')
    .add('./src/main/js/page/about.js')
    .bundle()
    .pipe(writestream);
});

build.sh

## This works as expected

## Make the common bundle
$(npm bin)/browserify \
 -t debowerify \
 -t deamdify \
 -r ./src/main/js/common.js \
 > src/main/resources/static/js/common.js

## Make the page bundle
$(npm bin)/browserify \
 -t deamdify \
 -t debowerify \
 -x ./lib/bower_components/jquery/jquery.js \
 -x ./lib/bower_components/flight/lib/index.js \
 ./src/main/js/page/about.js \
 > ./src/main/resources/static/js/about.js

common.js

// vendor modules
// located in lib/bower_components
require('es5-shim/es5-shim');
require('es5-shim/es5-sham');
require('jquery');
require('flight');
require('bootstrap');

// our modules
require('./ui/analytics');
require('./ui/analytics_listener').attachTo(document.body);

page.html

<script src="common.js"></script>
<script src="page.js"></script>

page.js

module.exports = function (nodeOrSelector) {
  // use "jquery" supplied by "common"
  var $ = require("jquery");
  // do page stuff with jquery or other modules from "common"
};
