Description

Nodemailer utilities module for Nest based on the nodemailer package.

Installation

$ npm i --save @iaminfinity/nodemailer

Usage

Import NodemailerModule:

@Module({
  imports: [
    NodemailerModule.register({
      host: 'smtp.example.com',
      port: 587,
      secure: false,
      auth: {
          user: 'username',
          pass: 'password'
      }
    })
  ],
  providers: [...]
})
export class AppModule {}

Inject NodemailerService:

@Injectable()
export class AppService {
  constructor(private readonly nodemailerService: NodemailerService) {}
}

Async options

Quite often you might want to asynchronously pass your module options instead of passing them beforehand. In such case, use registerAsync() method, that provides a couple of various ways to deal with async data.

1. Use factory

NodemailerModule.registerAsync({
  useFactory: () => ({
    host: 'smtp.example.com',
    port: 587,
    secure: false,
    auth: {
        user: 'username',
        pass: 'password'
    }
  })
})

Obviously, our factory behaves like every other one (might be async and is able to inject dependencies through inject).

NodemailerModule.registerAsync({
  imports: [ConfigModule],
  useFactory: async (configService: ConfigService) => configService.getMailConfig(),
  inject: [ConfigService],
})

2. Use class

NodemailerModule.registerAsync({
  useClass: NodemailerConfigService
})

Above construction will instantiate JwtConfigService inside JwtModule and will leverage it to create options objec

class NodemailerConfigService implements NodemailerOptionsFactory {
  createNodemailerOptions(): NodemailerModuleOptions {
    return {
      host: 'smtp.example.com',
      port: 587,
      secure: false,
      auth: {
        user: 'username',
        pass: 'password'
      }
    };
  }
}

3. Use existing

NodemailerModule.registerAsync({
  imports: [ConfigModule],
  useExisting: ConfigService
})

It works the same as useClass with one critical difference - NodemailerModule will lookup imported modules to reuse already created ConfigService, instead of instantiating it on its own.
