The Ultimate Getting Started with Angular Workshop - Devoxx France 2017

The Ultimate Getting Started with Angular Workshop - Devoxx France 2017

These slides are from a workshop I did at Devoxx France 2017. I showed how to set up an Angular development environment from scratch, develop a simple app, test it, integrating CSS frameworks (Angular Material and Bootstrap 4), secure it with OpenID Connect, and deploy it to the cloud.
