import { Inject, Injectable } from '@nestjs/common';
import type { IConfigurationService } from 'niro-health';

@Injectable()
export class AppService {
  constructor(
    @Inject('IConfigurationService')
    private readonly configurationService: IConfigurationService,
  ) {
  this.initialize();
}

  async initialize() {
    this.configurationService.setVariable('aws_api_version', 'latest');
    this.configurationService.setVariable('aws_region', 'us-east-1');
  }
}

Method of Use

To use this module, you need to inject it into the desired service.

import { Module } from '@nestjs/common';
import {
  AwsCoreService,
  AwsConfigurationService,
  AwsStsService,
  ConfigurationService,
  ValidatorRegexpService,
  StringExService,
} from 'niro-health';
import { AppController } from './app.controller';
import { AppService } from './app.service';

@Module({
  controllers: [AppController],
  providers: [
    AppService,
    {
      provide: 'IAwsCoreServiceImpl',
      useClass: AwsCoreService,
    },
    {
      provide: 'IAwsConfigurationService',
      useClass: AwsConfigurationService,
    },
    {
      provide: 'IAwsStsService',
      useClass: AwsStsService,
    },
    {
      provide: 'IConfigurationService',
      useClass: ConfigurationService,
    },
    {
      provide: 'IValidatorRegexpService',
      useClass: ValidatorRegexpService,
    },
    {
      provide: 'IStringExService',
      useClass: StringExService,
    },
  ],
})
export class AppModule {}

Injecting the module into our service.

import { Inject, Injectable } from '@nestjs/common';
import type { IAwsCoreServiceImpl } from 'niro-health';

@Injectable()
export class AppService {
  constructor(
    @Inject('IAwsCoreServiceImpl')
    private readonly awsCoreService: IAwsCoreServiceImpl,
  ) {}

  async configuration() {
    return await this.awsCoreService.configuration();
  }
}
