webpack/examples/code-splitting-depend-on-simple/README.md

This example shows how to use Code Splitting with entrypoint dependOn

# webpack.config.js

```javascript
module.exports = {
	entry: {
		app: { import: "./app.js", dependOn: ["react-vendors"] },
		"react-vendors": ["react", "react-dom", "prop-types"]
	},
	optimization: {
		chunkIds: "named" // To keep filename consistent between different modes (for example building only)
	},
	stats: {
		chunks: true,
		chunkRelations: true
	}
};
```

# app.js

```javascript
import react from "react";
import reactDOM from "react-dom";
import propTypes from "prop-types";

console.log(react, reactDOM, propTypes);
```

# dist/app.js

```javascript
(window["webpackJsonp"] = window["webpackJsonp"] || []).push([["app"],{
