@vetsmm/nestjs-sns

A thin wrapper around the [@aws-sdk/client-sns](https://www.npmjs.com/package/@aws-sdk/client-sns) library to be used in NestJs applications.

Note: The only methods available out of the box are publish and createTopic. If you need additional methods you can do one of the following.

1. Fork this repo and do as you please
2. Open an issue (or a PR ❤️)
3. Manually via this.snsService.snsClient.<SNS_METHOD>

Installation

npm install --save @vetsmm/nestjs-sns
#or
yarn add @vetsmm/nestjs-sns

Getting Started

Add and initialize the global module to your App.module.ts

Using .registerAsync() for dynamic values (preferred)

import { SnsModule } from 'nestjs-sns';

@Module({
  imports: [
    ConfigModule.forRoot(),
    SnsModule.registerAsync({
      imports: [ConfigModule],
      useFactory: async (configService: ConfigService) => ({
        endpoint: configService.get<string>('AWS_SNS_ENDPOINT'),
        region: configService.get<string>('AWS_REGION'),
      }),
      inject: [ConfigService],
      isGlobal: true,
    }),
  ],
  controllers: [AppController],
  providers: [AppService],
})
export class AppModule {}

Also supports useClass in registerAsync if you have a configuration class.

Using .register() for static values

import { SnsModule } from 'nestjs-sns';

@Module({
  imports: [
    SnsModule.register({
      endpoint: 'http://localhost:4566',
      region: 'us-east-1',
      // ...any other options accepted by SNS client
    }),
  ],
  controllers: [AppController],
  providers: [AppService],
})
export class AppModule {}

Usage

NOTE: If using the isGlobal: true option, you do not need to import this service into other modules that belong to App.module

import { Controller, Get } from '@nestjs/common';
import { SnsService } from 'nestjs-sns';
import { MessageService } from './message.service';

@Controller()
export class MessageController {
  constructor(
    private readonly messageService: MessageService,
    private readonly snsService: SnsService,
  ) {}

  @Get()
  async newMessage() {
    const snsRes = await this.snsService.publish({
      Message: 'Test Message',
      TopicArn: 'arn:aws:sns:us-east-1:000000000000:my-topic',
    });
    return snsRes;
  }
}
