What is the primary use case for Node Apollo Server in Node.js?

It is primarily used to build scalable, non-blocking backend architectures where I/O operations are offloaded to the event loop.

How does this integrate with Express or other web frameworks?

It integrates seamlessly as middleware or a core utility within the route handlers, allowing for high-performance request processing.

What are the common pitfalls when implementing Node Apollo Server?

Developers often forget to handle asynchronous errors or improperly manage memory, leading to memory leaks and blocked event loops.

1Apollo Federation

In a microservices architecture, you might have an Auth Server, a Product Server, and a Cart Server. Apollo Federation allows you to have 3 separate GraphQL schemas on 3 different servers, and automatically merges them into one single 'Supergraph' for the frontend. The frontend makes one query, and an Apollo Gateway splits it and routes it to the microservices.
