[???]nestjs Cross modules dependency injection

import module
providers service

So if you want use some controllers(this controllers is in some module), this time need to import module. ????

===========

Impotant：

constructor don't use new(). Use this.usersService.

src/auth/auth.service.ts

import { Component } from '@nestjs/common';
import { UsersService } from '../users';

@Component()   ?? Injectable
export class AuthService {
  constructor(
    private readonly usersService: UsersService,
  ) { }

  async validateUser(signedUser): Promise {
    const { email, password } = signedUser;
    const user = await this.usersService.findOneByEmail(email);
    return await EncryptorService.validate(password, user.password);
  }

Impotant：

exports need UsersService

src/users/users.module.ts

import { UsersService } from './users.service';

@Module({
    controllers: [UsersController],
    components: [UsersService],
    imports: [TypeOrmModule.forFeature([User])],
    exports: [UsersService],
})
