NestJS - Middleware

You want to apply two middleware, AuthMiddleware and LoggerMiddleware, only to POST requests on the /orders route. Which code correctly applies both middleware in NestJS?

Aconsumer.apply([AuthMiddleware, LoggerMiddleware]).forRoutes('orders');

Bconsumer.apply(AuthMiddleware).apply(LoggerMiddleware).forRoutes('orders');

Cconsumer.apply(AuthMiddleware, LoggerMiddleware).forRoutes({ path: 'orders', method: RequestMethod.POST });

Dconsumer.use(AuthMiddleware, LoggerMiddleware).forRoutes('orders');

Step-by-Step Solution

Solution:

Step 1: Understand how to apply multiple middleware
consumer.apply() accepts multiple middleware as separate arguments.
Step 2: Specify route and method correctly
Use forRoutes() with an object specifying path and method to limit to POST /orders.
Final Answer:
consumer.apply(AuthMiddleware, LoggerMiddleware).forRoutes({ path: 'orders', method: RequestMethod.POST }); -> Option C
Quick Check:
Multiple middleware in apply(), route+method in forRoutes() [OK]

Quick Trick: Pass multiple middleware as separate args to apply(), specify route+method in forRoutes() [OK]

Common Mistakes:

Chaining apply() calls instead of passing multiple middleware
Using use() instead of apply()
Passing middleware as array inside apply()
