Guide to messaging (example code only in nodejs)

1 - sudo chmod +x ./init.sh && ./init.sh
2 - goto each index file in src/ and run

There some difference reasons to choose between Rabbitmq, Kafka and Nats

• Nats: used for messaging with high performance, low latency (if payload of a message is small), if we need an messaging platform very simple and light weight, it built-in support pub/sub, req/reply, very easy to use. In core Nats we are not have persistent messages, but with JetStream enabled, Nats can take all advantages like Kafka and Rabbit, with JetStream Nats will be slower`.
• Rabbitmq: used for needing complex routing pattern (payload of a message is small too).
• Kafka: used for needing an Streaming platform (can be used as a Messaging platform). It only support pub/sub pattern, not have complex routing pattern, but sure it can process very large data and scale very well. It has more features like Kafka Connect for syncing data between resource, Kafka Stream for complex data processing, KSQL as a data source,...
