ReferenceError: jQuery is not defined

[mbiokyle29]

I am getting a jQuery is not defined error when trying to use the bootstrap-webpack plugin.

Here is my webpack.config.json

module.exports = {
    context: __dirname + "/src/",
    entry: "./jass.js",
    output: {
        path: __dirname + "/dist/",
        filename: "./bundle.js"
    },
    module: {
        loaders: [
            { test: /\.css$/, loader: "style!css" },
            { test: /\.woff\d*$/,   loader: "url-loader?limit=10000&minetype=application/font-woff" },
            { test: /\.ttf$/,    loader: "file-loader" },
            { test: /\.eot$/,    loader: "file-loader" },
            { test: /\.svg$/,    loader: "file-loader" },
        ]
    },
};

And here is my entry script

require("jquery");
require("bootstrap-webpack");
require('./style.css');

I have tried multiple different proposed solutions on SO but nothing seems to work. It seems that the issue is specifically in the bootstrap transition package.

This is from my bundle.js script

/* 11 */
/***/ function(module, exports, __webpack_require__) {

    /* ========================================================================

    +function ($) {
      'use strict';

      // CSS TRANSITION SUPPORT (Shoutout: http://www.modernizr.com/)
      // ============================================================

      function transitionEnd() {
        var el = document.createElement('bootstrap')

        var transEndEventNames = {
          WebkitTransition : 'webkitTransitionEnd',
          MozTransition    : 'transitionend',
          OTransition      : 'oTransitionEnd otransitionend',
          transition       : 'transitionend'
        }

        for (var name in transEndEventNames) {
          if (el.style[name] !== undefined) {
            return { end: transEndEventNames[name] }
          }
        }

        return false // explicit for ie8 (  ._.)
      }

      // http://blog.alexmaccaw.com/css-transitions
      $.fn.emulateTransitionEnd = function (duration) {
        var called = false
        var $el = this
        $(this).one('bsTransitionEnd', function () { called = true })
        var callback = function () { if (!called) $($el).trigger($.support.transition.end) }
        setTimeout(callback, duration)
        return this
      }

      $(function () {
        $.support.transition = transitionEnd()

        if (!$.support.transition) return

        $.event.special.bsTransitionEnd = {
          bindType: $.support.transition.end,
          delegateType: $.support.transition.end,
          handle: function (e) {
            if ($(e.target).is(this)) return e.handleObj.handler.apply(this, arguments)
          }
        }
      })
    }(jQuery);

Finally here is the output when I run webpack-dev-server

I am wondering if you have any tips on getting this figured out. Thanks for your time and thanks for developing/maintaining this package!

You need to expose the (jquery, $) variables for other third party libraries to use. Use this in your entry script

require('expose?$!expose?jQuery!jquery');

Also webpack as an argument called --display-error-details that will help you debug stuff like this.

This fixed it. Thank you very much!
