When responsibilities are split, the 'blast radius' of a bug is small. If you break the date formatter, only dates break. If you have a God File and make a syntax error, the entire server crashes and nothing works.

?Frequently Asked Questions

What is the primary use case for Node Split Responsabilities 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 Split Responsabilities?

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