Webpack - $ is not a function

Question

I am moving an existing webapp from requirejs to webpack.

I have an issue with the way jQuery is imported/shimmed.

In my bundled js, I am getting a $ is not a function error from within the bootstrap javascript.

When I console.log($) from within the bundled script it reveals an empty object: object {}

I am assuming that this is because nothing is exported from jQuery as it would traditionally set $ to the window object and be done.

Some research pointed me to use webpack plugins (see my webpack.config.js below) but this doesn't appear to solve the issue.

Is there anything wrong in my setup?

Thanks

My webpack.config.js:

    var path = require('path');
var webpack = require('webpack');
module.exports = {
    //devtool: 'source-map',

entry: ['./mobile.js'],
resolve: {
    root: "./js/",
    alias: {

        jquery: 'libs/jquery-1.9.1',
        underscore: "libs/lodash-1.0.1",
        //backbone: 'libs/backbone-1.0.0',
        backbone: 'libs/backbone-0.9.10',
        bootstrap: "libs/bootstrap-2.3.1",
        ......
    }
},
resolveLoader: {
    root: path.join(__dirname, 'node_modules')
},
output: {
    path: './',
    filename: 'bundle.js'
},
plugins: [
    new webpack.ProvidePlugin({
        $: "jquery",
        jQuery: "jquery",
        "window.jQuery": "jquery"
    })
],
module : {
    loaders: [
        { test: /\.html$/, loader: "text" },
        { test: /\.json$/, loader: "json" }
    ]


   }
}

The offending compiled bundle code:

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

    /* WEBPACK VAR INJECTION */(function(__webpack_provided_window_dot_jQuery) {/* ===================================================

You can also try exports-loader:

npm install --save-dev exports-loader

And config:

{
   include: require.resolve('libs/jquery-1.9.1'),
   loader: 'exports-loader?window.jQuery'
}

---

OR the problem can be in that ProviderPlugin doesn't read jquery alias, so try:

new webpack.ProvidePlugin({
    $: "libs/jquery-1.9.1",
    jQuery: "libs/jquery-1.9.1",
    "window.jQuery": "libs/jquery-1.9.1"
})
