|
|
<p>Most client libraries provide several ways to connect to the NATS server. The server itself is identified by a standard URL with the <code>nats</code> protocol. Throughout these examples we will rely on a test server, provided by <a href="https://nats.io" target="_blank">nats.io</a>, at <code>nats://demo.nats.io:4222</code>, where <code>4222</code> is the default port for NATS.</p>
|
|
<p>NATS clients also support the <code>tls</code> protocol to indicate that the client wants to use TLS. So in the previous example we can replace <code>nats</code> with <code>tls</code> to get <code>tls://demo.nats.io:4222</code>.</p>
|
|
<p>The protocol requirement is being removed from many libraries, so that you can use <code>demo.nats.io:4222</code> as the URL and let the client and server resolve whether or not TLS is required.</p>
