Building Realtime Serverless APIs with GraphQL

on YouTube ↗50m

" summary

Builds a GraphQL layer over an existing Star Wars REST API using Apollo Server and shows subscriptions over WebSockets; demo reduces dozens of per-page REST calls to three backend calls by using Apollo data sources and caching/data loader behavior. Implements mutations that validate types, adds a pub/sub subscription channel that pushes planet updates to clients, and wraps the whole API as a serverless Azure Function, which deploys and runs successfully. subscriptions and data sources are the key enablers.
