Go Serverless with Cosmos DB, Azure Functions and Blazor

on YouTube ↗01h 01m

" summary

A working demo called Fly Cosmos demo ties five projects together: a console updater that writes flight price changes into Cosmos DB, an Azure Function with a Cosmos DB change feed trigger that forwards updates over HTTP to an ASP.NET SignalR hub, and a Blazor client that displays live prices. Everything runs locally with the Cosmos DB emulator, uses .NET/C#, Azure Functions, SignalR, Event Grid and Logic Apps, builds in about 90 minutes, and observes UI refreshes aggregated about 1–5 seconds due to change feed batching.
