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			`import React, { Component } from 'react'`

update with-loading example (#4836) Changes: * Split `Header` component trough `_document.js` and `_app.js` * Attached Router events with a way described in the [documentation](https://github.com/zeit/next.js#router-events) (though in the documentation is says it should be `Router.events.on` while I managed to get it working only by `Router.router.events.on` and I had to place it inside `componentDidMount`) 2018-08-12 02:39:48 +00:00			`return <p>This is about Next!</p>`
