NestJS - Interceptors

Which of the following is the correct syntax to create a basic TimeoutInterceptor class in NestJS?

Aexport class TimeoutInterceptor implements NestInterceptor { intercept(context, next) { return next.handle().pipe(timeout(5000)); } }

Bexport class TimeoutInterceptor { intercept(context, next) { return next.handle().pipe(timeout(5000)); } }

Cexport class TimeoutInterceptor implements NestInterceptor { intercept(context) { return next.handle().pipe(timeout(5000)); } }

Dexport class TimeoutInterceptor implements NestInterceptor { intercept(next) { return next.handle().pipe(timeout(5000)); } }

Step-by-Step Solution

Solution:

Step 1: Check interface implementation and method signature
The interceptor must implement NestInterceptor and have intercept(context, next) method.
Step 2: Verify usage of next.handle() and RxJS timeout
The method should return next.handle().pipe(timeout(5000)) to apply timeout.
Final Answer:
export class TimeoutInterceptor implements NestInterceptor { intercept(context, next) { return next.handle().pipe(timeout(5000)); } } -> Option A
Quick Check:
Correct syntax = export class TimeoutInterceptor implements NestInterceptor { intercept(context, next) { return next.handle().pipe(timeout(5000)); } } [OK]

Quick Trick: Implement NestInterceptor with intercept(context, next) method [OK]
