Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

Este pacote é projetado para simplificar a comunicação entre microserviços em sua aplicação Adonis. Atualmente, ele suporta a integração com o Apache Kafka e está planejado para adicionar suporte a outros sistemas de mensagens, como RabbitMQ e gRPC no futuro.

npm i @djpfs/adonisjs-microservices

Após a instalação, execute o seguinte comando para configurar o pacote:

node ace configure @djpfs/adonisjs-microservices

Este comando irá configurar os arquivos necessários para o funcionamento do pacote no seu projeto.

npm i kafkajs

Adicione as seguintes configurações ao seu arquivo .env substituindo os valores de acordo com o seu ambiente:

KAFKA_CLIENT_ID='service-gateway'
KAFKA_GROUP_ID='gateway'
KAFKA_BROKERS='kafka1:9092,kafka2:9093,kafka3:9094'
KAFKA_SSL=false
KAFKA_SASL=false
KAFKA_SASL_MECHANISM='scram-sha-512'
KAFKA_SASL_USERNAME='username'
KAFKA_SASL_PASSWORD='password'
KAFKA_LOG_LEVEL=4
import { MsMessage } from "App/Decorators/MsMessage";
import { KafkaPayload } from "App/Helpers/Types/Microservice";

export default class AuthController {

  @MsMessage('kafka.auth.login')
  public async login(message: KafkaPayload) {
    console.log(message.message)
  }
}

O decorator espera um string como parametro, que deve ter pelo menos um . (ponto) para separar o nome transporte do tópico. O nome do transporte deve ser o mesmo que você definiu no arquivo de configuração do pacote.

Ex: kafka.auth.login, onde "kakfa" é o nome do transporte e "auth.login" é o nome do tópico

Para enviar mensagens, você deve importar o Transports e o KafkaTransport no seu arquivo de controller e usar o método send do transport para enviar a mensagem:

import Transports from "@ioc:Microservice/Transports";
import KafkaTransport from '@djpfs/adonisjs-microservices/build/src/transports/kafka'

export default class AuthController {

  public async sendMessage() {
    const transport: KafkaTransport = Transports.getTransport('kafka')
    await transport.producer.send({
      topic: 'auth.login',
      messages: [
        { value: 'Hello KafkaJS user!' },
      ],
    })
  }
}

Você pode configurar o kafka com todas as configurações disponíveis no pacote kafkajs editando as configurações no arquivo config/microservices.ts:
