What is the primary use case for Node .Dockerignore use 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 .Dockerignore use?

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

Packages like 'bcrypt' or 'node-sass' use C++ bindings. When you run 'npm install' on your Mac, it compiles the C++ specifically for Apple Silicon (ARM64). If you copy that node_modules folder into an Alpine Linux (x86_64) container, the moment Node tries to require 'bcrypt', the server crashes with a 'wrong architecture' error. The container MUST run its own 'npm install'.
