BullMQ Tutorial in Node.js: Step-by-Step with Redis & Docker | Real Project & Microservice Usage

In this video, we will see the complete tutorial of BullMQ Implementation in NodeJs using Docker and Redis. BullMQ is used to build a queue system that helps resolve many modern micro-services architectures. It is a fast and robust queue system built on top of Redis (We require Redis) But don't worry if you don't have Redis installed on your machine. In this video, I have also explained you, how can you instal Redis on your machine in just two minutes!.

This is the best video out there on BullMQ / Message Queue, where we have implemented it on the real project!

🧑🏻‍💻 Real-world project implementation!
We have created a very simple e-commerce server & implemented a queue system in a microservice-based architecture so that you guys can clearly understand how to work with queue systems on real-world projects.

We are straight to the point. So we have not implemented the validation, gateway system, and all other things that are not really necessary to explain to you the workings of Message Queue, We have skipped those parts, and we have directly implemented the communication between different microservices.

✏️ Microservices Includes in this video:
1. Order Service
2. User Server
3. Mail service

🧑🏻‍💻 Software used in this video
1. VsCode - Code Editor
2. Docker - To run Redis
3. Redis Insight - GUI for Redis that allows us ti interact with our databases and manage your data
4. Postman - To test our APIs

The library is designed so that it will fulfill the following goals:
1. Exactly once queue semantics, i.e., attempts to deliver every message exactly one time, but it will deliver at least once in the worst-case scenario.
2. Easy to scale horizontally. Add more workers for processing jobs in parallel.
3. Consistent.
4. High performance. Try to get the highest possible throughput from Redis by combining efficient .lua scripts and pipelining.

🧠 Knowledge
1. Why to use Message Queue?
Message Queue is an essential technique that is used in Microservice applications to transfer data from one service to another, in other words, we can say, that when any service wants to communicate with another service, then, in this case, we use message queues.

2. What exactly is Microservice Architecture?
A microservice is an architectural style where a large application is composed of small, independent services that communicate over various techniques and a message queue is one of them. Each microservice focuses on a specific business function and can be developed, deployed, and scaled independently
