|
|
<p>First, it is recommended to understand the relation between Streaming and core NATS. You should familiarize yourself with the <a href="../../nats_streaming/relation-to-nats.html">concept</a>.</p>
|
|
<p>NATS Streaming is a service on top of NATS. To connect to the service you first connect to NATS and then use the client library to communicate with the server over your NATS connection. Most of the libraries provide a convenience mechanism for connecting in a single step. These convenience methods will take some NATS options, like the cluster ID, and perform the NATS connection first, then run the protocol to connect to the streaming server.</p>
|
|
<p>Connecting to a streaming server requires a cluster id, defined by the server configuration, and a client ID defined by the client.</p>
|
|
<p><em>Client ID should contain only alphanumeric characters, <code>-</code> or `</em>`_</p>
|
|
<p>Connecting to a server running locally on the default port is as simple as this:</p>
|
|
<pre class="language-"><code class="lang-go">sc<span class="token punctuation">,</span> err <span class="token operator">:=</span> stan<span class="token punctuation">.</span><span class="token function">Connect</span><span class="token punctuation">(</span>clusterID<span class="token punctuation">,</span> clientID<span class="token punctuation">)</span>
|
|
</code></pre>
|
|
<p>If the server runs on port <code>1234</code>:</p>
|
|
