I am using webpack to bundle up my javascript files.
My Webpack config (which is passed to webpack using gulp) looks like this:
var webpackConfig = {
context: __dirname,
entry: {
"app": "./js/app.js"
},
output: {
path: path.join(__dirname, ".."),
filename: "/js/[name].js",
chunkFilename: "/js/[id].js"
},
plugins: [
new webpack.ResolverPlugin(
new webpack.ResolverPlugin.DirectoryDescriptionFilePlugin("bower.json", ["main"])
)
],
resolve: {
modulesDirectories: ['js', 'bower_components', 'node_modules']
}
};
My app.js
is a simple require:
require('modernizr/modernizr.js');
Webpack builds the file without any problems and the generated file contains modernizr.
The problem is that when I include the file on a page and test it, modernizr errors out:
TypeError: document is undefined
docElement = document.documentElement,
The bundled file from webpack looks like this:
/******/ (function(modules) { // webpackBootstrap
/******/ // The module cache
/******/ var installedModules = {};
/******/
/******/ // The require function
/******/ function __webpack_require__(moduleId) {
/******/
/******/ // Check if module is in cache
/******/ if(installedModules[moduleId])
/******/ return installedModules[moduleId].exports;
/******/
/******/ // Create a new module (and put it into the cache)
/******/ var module = installedModules[moduleId] = {
/******/ exports: {},
/******/ id: moduleId,
/******/ loaded: false
/******/ };
/******/
/******/ // Execute the module function
/******/ modules[moduleId].call(module.exports, module, module.exports, __webpack_require__);
/******/
/******/ // Flag the module as loaded
/******/ module.loaded = true;
/******/
/******/ // Return the exports of the module
/******/ return module.exports;
/******/ }
/******/
/******/
/******/ // expose the modules object (__webpack_modules__)
/******/ __webpack_require__.m = modules;
/******/
/******/ // expose the module cache
/******/ __webpack_require__.c = installedModules;
/******/
/******/ // __webpack_public_path__
/******/ __webpack_require__.p = "";
/******/
/******/ // Load entry module and return exports
/******/ return __webpack_require__(0);
/******/ })

What's causing this problem?
