## The idea behind the example

This example features:

* An app with four simple pages
* The "about" page uses the imperative (i.e.: "manual") prefetching API to prefetch on hover
* It will prefetch all the pages in the background except the "contact" page
Add deploy now button to the top of all example READMEs (#1763) * Add deploy now button to the top of all example READMEs * Remove unnecessary whitespace changes 2017-04-22 12:51:51 +00:00			`[![Deploy to now](https://deploy.now.sh/static/button.svg)](https://deploy.now.sh/?repo=https://github.com/zeit/next.js/tree/master/examples/with-prefetching)`
Prefetch pages with Service Workers (#375) * Register the service worker. * Update prefetcher code to do prefetching. * Implement the core prefetching API. support "import <Link>, { prefetch } from 'next/prefetch'" * Implement a better communication system with the service worker. * Add a separate example for prefetching * Fix some typos. * Initiate service worker support even prefetching is not used. This is pretty important since initiating will reset the cache. If we don't do this, it's possible to have old cached resources after the user decided to remove all of the prefetching logic. In this case, even the page didn't prefetch it'll use the previously cached pages. That because of there might be a already running service worker. * Use url module to get pathname. * Move prefetcher code to the client from pages Now we also do a webpack build for the prefetcher code. * Add prefetching docs to the README.md * Fix some typo. * Register service worker only if asked to prefetch We also clean the cache always, even we initialize the service worker or not. 2016-12-15 19:13:40 +00:00			`# Example app with prefetching pages`
