j0lv3r4 and timneutkens Test updater script on examples folder (#5993)
I wrote a [script](https://github.com/j0lv3r4/dependency-version-updater) to update dependencies recursively in `package.json` files, e.g.:

```
$ node index.js --path="./examples" --dependencies="react=^16.7.0,react-dom=^16.7.0"
```

This PR contains the result against the examples folder.

The idea behind the example

Sometimes when switching between pages, Next.js needs to download pages(chunks) from the server before rendering the page. And it may also need to wait for the data. So while doing these tasks, browser might be non responsive.

We can simply fix this issue by showing a loading indicator. That's what this examples shows.

It features:

  • An app with two pages which uses a common Header component for navigation links.
  • Using next/router to identify different router events
  • Uses nprogress as the loading indicator.
