webpack 설정을 아래와 같이 변경하여 이슈를 해결하였다.

원인
일반적인 jQuery Plugin 의 경우에는 아래와 같다.
node_modules/bootstrap/dist/js/bootstrap.js
/*!
* Bootstrap v3.3.7 (http://getbootstrap.com)
* Copyright 2011-2016 Twitter, Inc.
* Licensed under the MIT license
*/
...
+function ($) {
'use strict';
...
$(window).on('load', function () {
$('[data-spy="affix"]').each(function () {
var $spy = $(this)
var data = $spy.data()
data.offset = data.offset || {}
if (data.offsetBottom != null) data.offset.bottom = data.offsetBottom
if (data.offsetTop != null) data.offset.top = data.offsetTop
Plugin.call($spy, data)
})
})
}(jQuery);
Error 가 발생한 jQuery Plugin 의 소스는 아래와 같았다.
1004lucifer
node_modules/bootstrap-wysiwyg/src/bootstrap-wysiwyg.js
/* jshint browser: true */
( function( window, $ )
{
"use strict";
...
$.fn.wysiwyg = function( userOptions ) {
var wysiwyg = new Wysiwyg( this, userOptions );
};
} )( window, window.jQuery );
사용하려는 jQuery Plugin 이 예전형식의 jQuery Load 형식을 취해서 오류가 발생을 했었다.
jQuery Plugin 소스를 열어보지 않았다면 알 수 없었을 상황..ㅠ
한참동안 삽질하다 겨우 찾았다.
