This example shows how to use multiple entry points with a commons chunk.

In this example you have two (HTML) pages `pageA` and `pageB`. You want to create individual bundles for each page. In addition to this you want to create a shared bundle that contains all modules used in both pages (assuming there are many/big modules in common). The pages also use Code Splitting to load a less used part of the features on demand.

You can see how to define multiple entry points via the `entry` option.

You can use

You can see the output files:

- `commons.js` contains:
  - module `common.js` which is used in both pages
- `pageA.js` contains: (`pageB.js` is similar)
  - the module system
  - chunk loading logic
  - the entry point `pageA.js`
  - it would contain any other module that is only used by `pageA`
- `406.js` is an additional chunk which is used by both pages. It contains:
  - module `shared.js`

You can also see the info that is printed to console. It shows among others:

- the generated files
- the chunks with file, name and id
  - see lines starting with `chunk`
- the modules that are in the chunks
- the reasons why the modules are included
- the reasons why a chunk is created
  - see lines starting with `>`

# pageA.js

```javascript
var common = require("./common");
require(["./shared"], function(shared) {
	shared("This is page A");
});
```

# pageB.js

```javascript
var common = require("./common");
require.ensure(["./shared"], function(require) {
	var shared = require("./shared");
	shared("This is page B");
});
```

# webpack.config.js

```javascript
module.exports = {
	// mode: "development || "production",
	entry: {
		pageA: "./pageA",
		pageB: "./pageB"
	},

			cacheGroups: {
				commons: {
					name: "commons",
					chunks: "initial",
					minChunks: 2,
					minSize: 0
				}
			}
		},
		chunkIds: "deterministic" // To keep filename consistent between different modes (for example building only)
	}
};
```
