ms-nestjs-eureka is a NestJS module that provides an integration with eureka-js-client

Getting Started

You need to import the EurekaModule in your application:

EurekaModule.forRoot({
  eureka: {
    host: 'eureka-service',
    port: 8761,
    registryFetchInterval: 1000,
    servicePath: '/eureka/apps/',
    maxRetries: 3,
    //debug: true
  },
  service: {
    name: 'my-service',
    port: 8080,
  },
})

Use with NestJS Microservices

ClientsModule.registerAsync([
  {
    name: 'MS_SERVICE1',
    imports: [EurekaModule],
    useFactory: async (discoveryService: DiscoveryService) => {
      const instance = await discoveryService.getInstanceByAppId('my-service');

      return {
        transport: Transport.TCP,
        options: {
          host: instance.hostName,
          port: instance.port,
        },
      };
    },
    inject: [DiscoveryService],
  },
])
