Why i from RequireJS to webpack

RequireJS is a Asynchronous Module Definition(AMD) lib

Its powerful to handle modulize on your page and you can handle all loader on JavaScript, you can focus on JavaScript function and web page.

But if your module is become complex and more module, you can find JavaScript request become more and more.

You can find it is a serious performance problem.

Your network has lot of request of js.

I want to less or one js request on a page

So i choice webpack this tool.

It’s powerfull tool handle module bundle.

This is what i want change.

If want to use a lib for global like jQuery

Must use npm install & use ProvidePlugin in webpack.config.js

...
plugins: [
    new webpack.ProvidePlugin({
        $: "jquery",
        jQuery: "jquery",
        "window.jQuery": "jquery"
    }),
],
...

How it run

You can use

webpack
# if you want watch change
webpack --watch
