In this session, you’ll learn how to build microservices with Spring Boot, deploy them to the cloud, and expose their functionality with a progressive web application that can run offline. You’ll learn how to “build to fail” and create a quality, resilient application. Live coding will show how to use: Spring Boot, Spring Cloud, Cloud Foundry, IntelliJ IDEA, Angular, Spring Security, OpenID Connect, JWTs, and Progressive Web Apps.

17. Mobile Hates You!
How to fight back:
Implement PRPL
Get a ~$150-200 unlocked Android (e.g. Moto G4)
Use chrome://inspect && chrome://inspect?tracing
Lighthouse
DevTools Network & CPU Throttling

18. The PRPL Pattern
Push critical resources for the initial URL route
Render initial route
Pre-cache remaining routes
Lazy-load and create remaining routes on demand
