Durable Functions Example

This repo provides the demo code that accompanies the talk we gave at Future Tech 2019, Utrecht, The Netherlands.

Full-fledged single page application

The demo entails a full-fledged responsive web app that integrates with an Azure (Durable) Functions back-end:

• Azure Active Directory Authentication
• WebSockets with Azure SignalR Service
• Angular
• Responsive web design
• Google Material

Demo: Cancellable long-running workflow

Demo: Monitoring of a Flights Data API

Demo: Cloud-scale fractal processor

Security

A note on security: in the demo's current version the durable function secret code is shared with the single page application. This is generally not a good idea as the secret code grants access to all durable functions. This design needs to be revisited and only the orchestrator id or a derivate should be shared.
