AMQParty

All I wanted was to build a great microservices using RabbitMQ. but I can't understand all these terms... and all this boilerplate.. waaaa...

So lets party.

Installing

npm install --save amqparty

Using

const amqparty = require('amqparty');
 
// Just connect with the amqp library settings
amqparty.connect({ ...amqpProperties }).then(() => {
  console.log("Connected..");
  const send = amqparty.sender({ exchange: 'joe', name: 'userInfo' });
 
  send({
    some: 'data',
    iWould: 'like to send'
  }).then(data => {
    console.log('got myself: ', data);
  }).catch(err => {
    console.error('oh noes: ', err);
  });
});

Handling data in a service

const { connect, handle } = require('amqparty');
 
const listen = () => {
  console.log("Started...");
  handle({
    exchange: 'joe',
    name: 'userInfo'
  }, (data, resolve, reject) => {
    // Do your thing here...
    resolve({
      heyYou: 'ohai'
    });
  });
};
 
connect({ ...amqProperties }).then(listen);

How it works

sender

• creates a queue('joe', 'userInfo')
• returns a function that:
  • generates a uuid
  • add a subscriber to the subscribers object:
    • will call the callback
    • unbind the queue
    • remove the subscriber from the subscribers object
  • binds the queue to userInfo.response.${uuid}
  • sends data

handle({ exchange: 'joe', name: 'userInfo' }, callback...)

creates a queue (userInfo) that binds to userInfo.request
