We have provided Walkthroughs for you to try NATS (and JetStream) on your own. In order to follow along with the walkthroughs, you could choose one of these options:
The nats CLI tool must be installed, and a local NATS server must be installed (or you can use a remote server you have access to).
You can use Synadia's NGS.
You could even use the demo server from where you installed NATS. This is accessible via nats://demo.nats.io (this is a NATS connection URL; not a browser URL. You pass it to a NATS client application).
Please refer to the .
If you are going to run a server locally you need to first install it and start it. Please refer to the
Alternatively if you already know how to use NATS on a remote server, you only need to pass the server URL to nats using the -s option or preferably create a context using nats context add, to specify the server URL(s) and credentials file containing your user JWT.
To start a simple demonstration server locally, simply run:
(or nats-server -m 8222 if you want to enable the HTTP monitoring functionality)
When the server starts successfully, you will see the following messages:
The NATS server listens for client connections on TCP Port 4222.
