Request:

{
  "data": {
    "a": 2, 
    "b": 3
  },
  "chain": [
    {
      "exchange": "math",
      "key": "math.sum",
      "isMultiple": false
    },
    {
      "exchange": "math",
      "key": "sum.next",
      "isMultiple": false
    }
  ],
  "config": null
}

const babex = require('babex-node');
const exchange = 'math';
const routingKey = 'math.sum';
const config = babex.config;
config.name = 'math.sum';
config.address = process.env.RMQ_ADDRESS;

babex
    .newService(config)
    .then((service) => service
        .bindToExchange(exchange, routingKey)
        .then((service) => service
            .listen((message) => {
                let payload = {
                    c: message.data.a + message.data.b
                };
                
                service.next(message, payload);

    .catch(console.warn);

Result:
