Kafka

This tutorial will help you understand how to use two components designed to communicate with Apache Kafka. They are KafkaConnection and KafkaMessageQueue.

Messaging basics

This tutorial will help you understand how and when to use the MemoryMessageQueue component. First, it explains the basics of this component and the necessary pre-requisites. Then, it explains how to create a message receiver and an instance of the MemoryMessageQueue, add a listener to it, send and receive a message, and close the component. It ends by summarizing the learned points in a single program and wrapping up the concepts seen in this tutorial.

MQTT

In this tutorial, we will see how to create a message queue with MqttMessageQueue, which is a component available in the mqtt module. First, we will see the necessary pre-requisites and how to create a basic message queue. Then, we will learn how to create a message and send it to an MQTT app, such as Eclipse Mosquitto, and read messages from such an app. Finally, we will have a summary of all the learned concepts.

NATS

This tutorial will help you understand how the NatsMessageQueue component is used. First, we will see a brief description of this class and how to import it. Then, we will implement this component, connect it, and create and send a message to a NATS server from it. Finally, we will combine the code into a complete program and summarize what we have learned.

RabbitMQ

In this tutorial, you will learn how to send and receive messages via RabbitMQ. First, we will see the necessary pre-requisites. Then, we will learn how to implement this component, connect to RabbitMQ and send and receive messages from it. Finally, we will combine the different sections into a program and summarize all the learned concepts.
