PR Type
What kind of change does this PR introduce?
What is the current behavior?
There is no way to execute logic before Guards in microservice message handlers. This makes it impossible to set up request-scoped context (e.g., AsyncLocalStorage-based correlation ID propagation) that needs to be available to Guards and downstream handlers.
Issue Number: #1627
What is the new behavior?
NestMicroservice now exposes useGlobalPreRequestHooks(...hooks) which registers hooks that execute before Guards for every pattern handler.
Each hook receives ExecutionContext and an Observable-returning next() function:
Execution order per request:
preRequest hooks -> Guards -> Interceptors -> Pipes -> Handler
Key design decisions:
Does this PR introduce a breaking change?
