Browserify with twitter bootstrap

Question

There are many similar questions including answers here on stack overflow, but none of them have worked for me, so here I am asking you guys. I appreciate everyone's time.

I recently started using gulp with browserify, and that works great. I then tried to use browserify for the front-end using: Backbone and Bootstrap3.

things are appearing to work, until I try to require the js file that comes with Bootstrap. I get an error in my chrome tools stating: jQuery is undefined.

I have attempted to shim it in, but I am very confused by the shim. I am using jQuery 2.1.1, so I should not need to shim jQuery, but it exists in the shim now, as I was desperate and trying everything. Here is my package.json and my main.js file:

    "bootstrap": {
      "depends": [
        "jQuery"
      ]
    }
  }
}

------------------------- main.js ----------------------

var shim = require('browserify-shim');
$ = require('jquery');
var Backbone = require('backbone');
Backbone.$ = $;
var bootstrap = require('bootstrap');

/* the following logs fine if I comment out the bootstrap require, otherwise I get 'jQuery undefined' */

console.log(Backbone);
$(function() {
    alert('jquery works');
});

You shouldn't need to shim jquery that way if you've installed it with npm. The following works for a project I've been writing:

I've also learned that using npm for bootstrap is kind of a PITA. I've been using bower to install and maintain certain front-end components when they need to be shimmed like this.

package.json:

{
  "name": "...",
  "version": "0.0.1",
  "description": "...",
  "repository": {
    "type": "git",
    "url": "..."
  },
  "browser": {
    "d3js": "./bower_components/d3/d3.min.js",
    "select2": "./bower_components/select2/select2.min.js",
    "nvd3js": "./bower_components/nvd3/nv.d3.min.js",
    "bootstrap": "./node_modules/bootstrap/dist/js/bootstrap.js"
  },
  "browserify": {
    "transform": [
      "browserify-shim",
      "hbsfy"
    ]
  },
  "browserify-shim": {
    "d3js": {
      "exports": "d3",
      "depends": [
        "jquery:$"
      ]
    },
    "bootstrap": {
      "depends": [
        "jquery:jQuery"
      ]
    },
    "select2": {
      "exports": null,
      "depends": [
        "jquery:$"
      ]
    },
    "nvd3js": {
      "exports": "nv",
      "depends": [
        "jquery:$",
        "d3js:d3"
      ]
    }
  },
  "devDependencies": {
    "browserify-shim": "~3.4.1",
    "browserify": "~3.36.0",
    "coffeeify": "~0.6.0",
    "connect": "~2.14.3",
    "gulp-changed": "~0.3.0",
    "gulp-imagemin": "~0.1.5",
    "gulp-notify": "~1.2.4",
    "gulp-open": "~0.2.8",
    "gulp": "~3.6.0",
    "hbsfy": "~1.3.2",
    "vinyl-source-stream": "~0.1.1",
    "gulp-less": "~1.2.3",
    "bower": "~1.3.3",
    "cssify": "~0.5.1",
    "gulp-awspublish": "0.0.16",
    "gulp-util": "~2.2.14",
    "gulp-rename": "~1.2.0",
    "gulp-s3": "git+ssh://[email protected]/nkostelnik/gulp-s3.git",
    "gulp-clean": "~0.2.4",
    "process": "~0.7.0"
  },
  "dependencies": {
    "backbone": "~1.1.2",
    "jquery": "~2.1.0",
    "lodash": "~2.4.1",
    "d3": "~3.4.8",
    "rickshaw": "~1.4.6",
    "datejs": "~1.0.0-beta",
    "moment": "~2.7.0"
  }
}

js:

$ = jQuery = require('jquery');
var _ = require('lodash');
var Rickshaw = require('rickshaw');
var d3 = require('d3js');
var nvd3 = require('nvd3js');
var moment = require('moment');
require('datejs');
require('select2');

var bootstrap = require('bootstrap');
console.log(bootstrap)

Also - one sometimes useful thing is to have browserify-shim output its diagnostics. This is what my browserify.js task looks like:

var browserify   = require('browserify');
var gulp         = require('gulp');
var handleErrors = require('../util/handleErrors');
var source       = require('vinyl-source-stream');
var process      = require('process');

process.env.BROWSERIFYSHIM_DIAGNOSTICS=1;

var hbsfy = require('hbsfy').configure({
  extensions: ['html']
});

gulp.task('browserify', ['images', 'less'], function(){
    return browserify({
      transform: ['hbsfy', 'cssify'],
            entries: ['./src/javascript/app.js'],
        })
        .bundle({debug: true})
        .on('error', handleErrors)
        .pipe(source('app.js'))
        .pipe(gulp.dest('./build/'));
});
