robot-queue-service

An npm module to support bidirectional communications via a work queue implementation focused on robot communications.

Note: Earlier implementations of this module supported the beanstalkd work queue implementation. As of version 1.3+ it has been switched over to use RabbitMQ. The primary motivation for this change was the built-in security mechanisms in RabbitMQ vs beanstalkd. Having to use Stunnel to provide equivalent security for beanstalkd turned out to be unstable in weak network environments.

Usage

The following is an example of how you might set this up.

const queueSVC = require('robot-queue-service');

const securityOptions = {
  cert: fs.readFileSync(options.clientCert),
  key: fs.readFileSync(options.clientKey),
  rejectUnauthorized: false,
  ca: [ fs.readFileSync(options.caCert) ]
}

...

const workerFunction = (message) => {
  console.log("The message received")
}

queueSVC.connect("amqps://localhost:5671", serverOptions)
  .then( () => {
    return queueSVC.createChannel()
      .then((ch) => {
        return queueSVC.consume(null, 'theQueue', workerFunction)
      })
  )}
  .catch((err) => {
    console.error("Error dealing with the queue: %j")
  })
