This session will be consisting of 4 parts:
1) A overview of offline technologies and Drupal's place in it. We will quickly cover all the emerging offline / instant / fast technologies with simple examples. Showing their strengths, weaknesses and for which type of clients you can use them. (Google's AMP, Facebook's instant articles, the failed Appcache & Serviceworkers) Compared to what native apps give you, and what is this Progressive Web App everyone talks about
2) Frontend United's example: live demo of an offline webapp built in Appcache.
4) The final part will be a live demo from what PWA is able to do on an existing big project.
This session will be a merged session from nod_'s Drupalaton-talk and Swentel & MathieuSpil's talk in Drupal Dev Days mixed up with some new examples.
