AMQP 0-9-1 library and client for Node.JS

NPM version NPM downloads Node.js CI amqplib

npm install amqplib

A library for making AMQP 0-9-1 clients for Node.JS, and an AMQP 0-9-1 client for Node.JS v10+.

This library does not implement AMQP 1.0 or AMQP 0-10.

Project status:

  • Expected to work
  • Complete high-level and low-level APIs (i.e., all bits of the protocol)
  • Stable APIs
  • A fair few tests
  • Measured test coverage
  • Ports of the RabbitMQ tutorials as examples
  • Used in production

Still working on:

  • Getting to 100% (or very close to 100%) test coverage

Callback API example

const amqplib = require('amqplib/callback_api');
const queue = 'tasks';

amqplib.connect('amqp://localhost', (err, conn) => {
  if (err) throw err;

  // Listener
  conn.createChannel((err, ch2) => {
    if (err) throw err;


    ch2.consume(queue, (msg) => {
      if (msg !== null) {
      } else {
        console.log('Consumer cancelled by server');

  // Sender
  conn.createChannel((err, ch1) => {
    if (err) throw err;


    setInterval(() => {
      ch1.sendToQueue(queue, Buffer.from('something to do'));
    }, 1000);

Promise/Async API example

const amqplib = require('amqplib');

(async () => {
  const queue = 'tasks';
  const conn = await amqplib.connect('amqp://localhost');

  const ch1 = await conn.createChannel();
  await ch1.assertQueue(queue);

  // Listener
  ch1.consume(queue, (msg) => {
    if (msg !== null) {
      console.log('Received:', msg.content.toString());
    } else {
      console.log('Consumer cancelled by server');

  // Sender
  const ch2 = await conn.createChannel();

  setInterval(() => {
    ch2.sendToQueue(queue, Buffer.from('something to do'));
  }, 1000);

Running tests

npm test

To run the tests RabbitMQ is required. Either install it with your package manager, or use docker to run a RabbitMQ instance.

docker run -d --name amqp.test -p 5672:5672 rabbitmq

If prefer not to run RabbitMQ locally it is also possible to use a instance of RabbitMQ hosted elsewhere. Use the URL environment variable to configure a different amqp host to connect to. You may also need to do this if docker is not on localhost; e.g., if it's running in docker-machine.

One public host is

URL=amqp:// npm test

NB You may experience test failures due to timeouts if using the instance.

You can run it under different versions of Node.JS using nave:

nave use 10 npm test

or run the tests on all supported versions of Node.JS in one go:

make test-all-nodejs

(which also needs nave installed, of course).

Lastly, setting the environment variable LOG_ERRORS will cause the tests to output error messages encountered, to the console; this is really only useful for checking the kind and formatting of the errors.

LOG_ERRORS=true npm test
