Section: Full talk (40 mins) Technical level: Intermediate


Welcome to the web applications of 21st century! Give your users a native-like app experience: instant load, offline experience and push notifications. During this talk, you will get a high level overview of Progressive Web Application concept, how to get started with it in Angular CLI and WorkBox, potential pitfalls and how to address them.


This talk covers what Progressive Web App is, how it differentiate from traditional web application, and how to get started. By comparing ngsw (Angular CLI implementation) and WorkBox as an alternative, I am going to mention about following aspects of PWAs:

  • content caching (different strategies)
  • manifest file (what should be described in it)
  • push notifications
  • background sync

I am going also to cover common pitfalls (problems with Angular Universal) and browser support.
