we've all dealt with that one
monolithic validation function that grows into a complete nightmare. it usually starts as a single if statement but ends up being this massive, brittle mess of nested logic that everyone is ::scared to touch::. i recently revisited the
chain of responsibility pattern to see how it handles these expanding business rules. instead of one giant block, you just pass the request through a series of independent handlers.
>it turns a single point of failure into a modular pipeline.it's much easier to add new constraints without breaking the existing flow
unless you forget to link the next handler in the chain . has anyone else found success using this for complex auth flows or does it just add too much boilerplate?
