What is the primary use case for Node Autenticationn in GraphQL 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 Autenticationn in GraphQL?

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

1The Recursive Query

Because GraphQL is a graph, relationships go both ways. A hacker can send: query { user { posts { author { posts { author { posts } } } } } }. This infinite recursion will crash your server instantly. You MUST configure Apollo Server with a 'Depth Limit' validation rule (usually max depth of 5 or 6) to reject these malicious payloads.
