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:

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": {

"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/'));
});
There is error as I am using browserify which require the variable '$' or 'jQuery' to be defined.
adding the window to make it global resolve the error. Not sure if this would be the correct way to do, if not, let me know.
window.$ = window.jQuery = require('jquery');
var bootstrapjs = require('bootstrap-sass');
I've been wondering about this for a while. This simple solution does the job for me:
import foo from 'foo';
import bar from './bar';
import { default as $ } from "jquery";
global.$ = $;
global.jQuery = $; // This one does the trick for bootstrap!
// Boostrap's jQuery dependency only works with require, not with ES6 import!
const btp = require('bootstrap');
So to make Bootstrap to work with Browserify you're going to need one of Browserify CSS transforms.
First the index.js (browserify entry)
// Bootstrap needs jQuery on the Window
window.jQuery = $ = require('jquery');
// include popper.js if you want Bootstrap tooltips
window.Popper = require('popper.js');
// include bootstrap js libs (not the CSS libs as yet)
require('bootstrap');
// then the CSS Lib
require('bootstrap/dist/css/bootstrap.css');
NPM Installs:
npm install bootstrap@4.0.0-alpha.6 jquery popper.js
To use tooltips globally:
Per the Bootstrap docs.
$('[data-toggle="popover"]').popover();
I have a Browserify-Budo repo here. If you want to see it working.
