NestJS - Database with TypeORM

Given this NestJS module code, what will happen?

import { Module } from '@nestjs/common';
import { TypeOrmModule } from '@nestjs/typeorm';
import { User } from './user.entity';

@Module({
  imports: [TypeOrmModule.forFeature([User])],
})
export class UserModule {}

AUser entity is registered for database operations in this module

BTypeORM connection is established here

CUserModule will throw an error because forFeature is invalid

DUser entity is ignored and not available in this module

Step-by-Step Solution

Solution:

Step 1: Understand what TypeOrmModule.forFeature does
This method registers the given entities (here User) so they can be injected and used in this module's services and controllers.
Step 2: Confirm that connection setup is separate
Connection setup happens in forRoot(), not forFeature(), so no connection is established here.
Final Answer:
User entity is registered for database operations in this module -> Option A
Quick Check:
forFeature() registers entities [OK]

Quick Trick: forFeature() registers entities, forRoot() sets connection [OK]

Common Mistakes:

Thinking forFeature() establishes connection
Believing forFeature() is invalid
Assuming entities are ignored
