title: What are all the mongoose events and where are they documented?
body: <p>There are various events I can handle with mongoose, e.g.</p>
  
  <pre><code>mongoose.connection.on("connecting", () =&gt; this.onConnecting());
  </code></pre>
  
  <p>Some of those I've encountered:</p>
  
  <ul>
  <li>connecting</li>
  <li>error</li>
  <li>connected</li>
  <li>open</li>
  <li>reconnected</li>
  <li>disconnected</li>
  </ul>
  
  <p>I can't find where these are documented. I thought that maybe they weren't part of mogoose, but rather of mongodb itself, but I couldn't find them on the mongo site either.</p>
  
  <p>Where can I find these events (and others) documented?</p>
