NestJS - Interceptors

Which of the following is the correct way to implement the intercept method in a NestJS LoggingInterceptor?

Aintercept(context, next) { return next.handle(); }

Bintercept(context, next) { next.handle(); }

Cintercept(context) { return next.handle(); }

Dintercept(next) { return context.handle(); }

Step-by-Step Solution

Solution:

Step 1: Recall the intercept method signature
The intercept method receives two parameters: context and next. It must return next.handle() to continue the request lifecycle.
Step 2: Check each option for correct syntax
intercept(context, next) { return next.handle(); } correctly uses both parameters and returns next.handle(). Options A, C, and D either miss parameters or do not return the observable.
Final Answer:
intercept(context, next) { return next.handle(); } -> Option A
Quick Check:
intercept(context, next) returns next.handle() [OK]

Quick Trick: intercept always returns next.handle() with both parameters [OK]
