mongoose-kue

mongoose plugin to run mongoose schema methods in background.

Note!: It's highly advice to run worker(s) in separate process for better performance

Requirements

• NodeJS v10.0+

Install

$ npm install --save mongoose kue mongoose-kue

Usage

const mongoose = require('mongoose');
const { Schema } = mongoose;
const { plugin: runInBackground, worker } = require('mongoose-kue');

...

/* queue sendEmail instance method to run in background */
const job =
  user.runInBackground({ method: 'sendSMS', to: ['255714000111'] });

/* queue sendEmail static method in background */
const job =
  User.runInBackground({
    method: 'sendEmail',
    to: ['[email protected]', '[email protected]']
  });


/* ADVICED: in separate process start processing */
worker.start();

...

Options

Plugin

const { plugin: runInBackground } = require('mongoose-kue');

mongoose.plugin(runInBackground, {
  name: 'mongoose',
  prefix: 'q',
  MONGODB_URI: process.env.MONGODB_URI,
  redis: (process.env.REDIS_URL || {
    port: 1234,
    host: '10.0.50.20',
    auth: 'password',
    db: 3
  })
});

...

• name - Name of the worker queue to process background work,
• MONGODB_URI - Valid mongodb uri,
• attempts - Failure Attempts
• backoff - Failure Backoff
• All applicable kue connection settings

Worker

Note!: I highly recommend to run this in separate process

const mongoose = require('mongoose');
const { worker } = require('mongoose-kue');

/* load and register your models */

...

/* start worker queue to process in background */
worker.start({
  name: 'mongoose',
  concurrency: 10,
  prefix: 'q',
  MONGODB_URI: process.env.MONGODB_URI,
  redis: (process.env.REDIS_URL || {
    port: 1234,
    host: '10.0.50.20',
    auth: 'password',
    db: 3
  })
});

• name - Name of the worker queue to process background work,
• MONGODB_URI - Valid mongodb uri,
• concurrency - Processing Concurrency. Default to 10,
• timeout - Graceful shutdown delay,
• All applicable kue connection settings
