Queue with Bull in Node.js

This repository contains an example of pratical use of the Bull queue management system.

Getting Started

Prerequisites

This app is not Docker based, so you should install Node.js.

Node.js >= 10.x

Bull needs the Redis service to store and manage its jobs and messages. So, we can easily install Redis using Docker:

    docker run --name my_redis_container -d -p 6379:6379 -i -t redis:alpine

We're using nodemailer as a library to send mail messages. Nodemailer supports several types of SMTP transport, like Ethereal (for testing purposes). To receive the Ethereal access credentials, please follow the steps below:

1. Access the Ethereal Website: (https://ethereal.email/);
2. Click in "Create Ethereal Account";
3. Add your email username and password to .env file:

EMAIL_USERNAME=<YOUR_EMAIL_USERNAME_HERE>
EMAIL_PASSWORD=<YOUR_PASSWORD_HERE>

4. Access this link (https://ethereal.email/messages) to open your mailbox.
