Azure Queue Consumer

---

Azure Queue Consumer is a simple consumer that allows you to handle queue messages without having to worry about setting up the azure framework.

Installation

Node 18+ is required

pnpm i az-queue-consumer

or

npm i az-queue-consumer

Examples

import { AzureQueueConsumer } from 'az-queue-consumer';

const messageHandler = (messages) => {
  // do something with the message
}
const queueName = "sample-queue";
const connectionString = "DefaultEndpointsProtocol=https;AccountName=something;AccountKey=something==;EndpointSuffix=core.windows.net";
const listener = new AzureQueueConsumer(queueName, connectionString, messageHandler);

listener.on('queue::ready', () => { console.log("Listener is ready to receive messages!") });

listener.listen();

API

listen - The listen function starts the listener which in turns polls the queue every 10 seconds. The default, which is 10 seconds, can be chaged by setting pollingTime in options in the constructor.

on - Adds a event listener for specific events. Events are typed and custom handlers need to be passed. See below for full list of events

stop - Stops the listener and completes execution of any ongoing handler before quitting.

Events

• queue::ready - emitted when the client connects to the queue and is ready to receive messages
• message::onReceive - this event is emitted when the client receives a message
• handler::finish - once the handler finishes executing, this event is emitted
• handler::error - if the handler fails with an exception, the exception is emitted along with this event
• listener::error - the listener can encounter errors even after connecting such as connection errors. This event gets emitted during such as errors
• message::preDelete - Before deleting the message, this event is fired
• message::afterDelete - After successful deletion, this event gets fired
• queue::shutdown - when stop() is called, the queue emits this event and finished executing the current message
