Technical requirements
In this chapter, we will install the NATS server and configure it to demonstrate certain aspects of the NATS messaging system. Hence, you should have a basic understanding of using the command-line tools based on the operating system you are using. As a prerequisite, you can install the NATS server by following the instructions mentioned in the official NATS documentation: https://docs.nats.io/nats-server/installation. We will be using NATS server version 2.x (v2.2.2) to demonstrate the examples in this chapter.
