## 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](./components/Header.js) component for navigation links.
* Using `next/router` to identify different router events
* Uses [nprogress](https://github.com/rstacruz/nprogress) as the loading indicator.
Implement Router Events (#511) * Move route loading logic to a common place. * Add router events. * Add EventEmitter's core API methods. * Add example app for loading events and docs. * Fix some typos. * Get rid of Router.ready() * Remove events package. It's already shipping with webpack. * Handling aborting properly. * Expose simple attribute based events listener API. Removed the proposed event listener API from the public API. * Remove error logged when there's an abort error. There are many other ways to capture this error. So, it doesn't look nice to print this always. * Change router events to pass only the current URL as arguments. * Add a section about Cancelled Routes to README. 2016-12-31 01:15:22 +00:00			`# Example app with page loading indicator`
