### NestJS Integration

```typescript
import { Module } from '@nestjs/common';
import { ConfigModule, ConfigService } from '@nestjs/config';
import { NotifyModule } from '@mana/notify-client/nestjs';

@Module({
  imports: [
    ConfigModule.forRoot(),
    NotifyModule.forRootAsync({
      imports: [ConfigModule],
      useFactory: (config: ConfigService) => ({
        serviceUrl: config.get('MANA_NOTIFY_URL', 'http://localhost:3040'),
        serviceKey: config.get('MANA_NOTIFY_SERVICE_KEY'),
        appId: config.get('APP_ID'),
      }),
      inject: [ConfigService],
    }),
  ],
})
export class AppModule {}
```

Then inject the client:

```typescript
import { Injectable, Inject } from '@nestjs/common';
import { NOTIFY_CLIENT, NotifyClient } from '@mana/notify-client/nestjs';

@Injectable()
export class NotificationService {
  constructor(@Inject(NOTIFY_CLIENT) private readonly notify: NotifyClient) {}

  async sendWelcomeEmail(email: string, name: string) {
    await this.notify.sendEmail({
      to: email,
      template: 'auth-welcome',
      data: { userName: name },
    });
