PWAs with Ionic, Angular, and Spring Boot - Devoxx Poland 2017

In this session, I show how to build a Progressive Web App (PWA) using Ionic, Angular and Spring Boot. PWAs are being hyped as the next big thing in mobile development. This talk will cut through the hype and get down to the nitty-gritty. Are they really better than native applications? Can you develop PWAs and easily target mobile and desktop with the same application?
