# aEntry.js

```javascript
// Just show the page "a"
var render = require("./render");
render(require("./aPage"));
```

`bEntry.js` is similar. You may want to use a loader to generate this file.

# aPage.js

```javascript
module.exports = function() {
	return "This is page A.";
};
```

`bEntry.js` is similar.

# router.js

```javascript
var render = require("./render");

// Event when another page should be opened
// Maybe hook click on links, hashchange or popstate
window.onLinkToPage = function onLinkToPage(name) { // name is "a" or "b"
	// require the page with a dynamic require

	// It's important that this require only matches the pages
	//  otherwise there is blood in the bundle. Here this is done with a
	//  specific file prefix. It's also possible to use a directory,
	//  overwriting the RegExp with the ContextReplacementPlugin, or
	//  using the require.context method.

	// This line may throw a exception on runtime if the page wasn't found.
	import(/* webpackChunkName: "[request]" */`./${name}Page`).then(page => {;
