HotChocolate: An Introduction to GraphQL for ASP.NET Core

on YouTube ↗01h 10m

" summary

Demo shows HotChocolate on ASP.NET Core replacing many REST calls: fetching Luke’s co‑stars with swapi.co creates a data‑waterfall of 1.6 seconds and 100+ requests, the GraphQL layer reduces that to 42 milliseconds and 2.8 KB by letting clients ask for exact fields. HotChocolate integrates with Entity Framework via IQueryable to rewrite queries into one SQL, adds paging/filtering/sorting/projection middleware, and supports subscriptions via async streams (in‑memory topic bus demo wired but the live demo has a minor setup hiccup).
