amqplib-plus v1.0.3

Amqplib rabbitmq library objet oriented enhancement.


Amqplib-plus amplifies the original npm amqplib library with OOP approach.

Amqplib-plus adds following features:

  • connection auto-reconnect
  • easy to use object oriented publisher
  • easy to use object oriented consumer that runs user defined callback for every consumed message

How to install:

$ npm install amqplib-plus

How to use

Basic example - publish and consume

import {Connection, Consumer, Publisher} from "amqplib-plus";
import {Channel, Message} from "amqplib";

const queue = { name: "some_queue_name", options: {} };
const msgContent = "some content";

// callback to be called when creating the consumer, before it starts consuming
// consumer wants to be sure the queue exists
const consumerPrepare: any = (ch: Channel) => {
    return ch.assertQueue(, queue.options);

// the callback to be called on every consumed message
// you process the message as you like and tken ack/reject it as you wish
const handleMsg = (msg: Message, ch: Channel) => {

// creates the connection to rabbitmq broker
const amqpConn = new Connection(
    { connectionString: 'amqp://guest:guest@localhost:5672/' },
    console // you may use custom logger or avoid it to disable logging

// create the consumer using existing connection and start the consumption
const consumer = new Consumer(conn, consumerPrepare, handleMsg);
consumer.consume(, {});

// callback to be called when creating the publisher before it starts publishing
// publisher wants to be sure the publishing queue exists
const publisherPrepare: any = (ch: Channel) => {
    return ch.assertQueue(, queue.options);
// create the publisher using the existing connection
const publisher = new Publisher(conn, publisherPrepare);
// send a message that consumer should consume
publisher.sendToQueue(, Buffer.from(msgContent), {});

How to run the tests

If you have running rabbitmq instance, set env variable values defined used in test/config.ts (default rabbitmq dsn is 'amqp://guest:guest@localhost:5672/') and run: npm run test.

Or you can use custom rabbitmq instance in test by running RABBIT_DSN=amqp://guest:guest@yourserver:5672/ npm run test

Alternatively you can run: make test which will start rabbitmq instance for you and run tests in docker-compose.
