The simplest PWA to demonstrate how to speed up slow apps and add to homescreen / install to desktop.

• index.php has the required Manifest in the head section.
• An install button is hidden by default on index.php.
• The install button is displayed when PWA is ready to install.
• page1.php has a two second sleep to emulate slow server-side code.
• page2.php has a one second sleep and dynamic content (shows the current time, with seconds).
• The two slow pages are cached to load instantly, and page2 still has dynamic content.
• App works offline.
• Viewing page2 offline shows the last-cached time.
• As soon as networking comes back online, the clock starts ticking again.

Have fun!

Thoughts and to dos:

• How can we capture form POSTs when offline, to send them when the network comes back up?
• What's the best way to prevent certain user actions when offline?
• How can we disable caching on certain URLs? (Useful for lazy loading quick-changing content).
