# Connection Status

> Connection Status — CometChat documentation.

CometChat SDK provides you with a mechanism to get real-time status of the connection to CometChat web-socket servers. To achieve this you need to use the `ConnectionListener` class provided by the CometChat SDK

Connection Status provides you with the below 3 methods to get the status of the connection to CometChat web-socket servers:

| Delegate Method    | Information                                                                                                                                      |
| ------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------ |
| onConnecting       | This method is triggered when CometChat SDK is trying to establish a connection to the web-socket server.                                        |
| onConnected        | This method is called when CometChat SDK has successfully established a connection and now is connected.                                         |
| onDisconnected     | This method is called when the CometChat SDK gets disconnected due to any issue while maintaining the connection like network fluctuations, etc. |
| onFeatureThrottled | CometChat automatically toggles off certain features to prevent performance loss for end-users under various circumstances                       |

Once the connection is broken, the disconnected callback is triggered, the SDK automatically tries to establish the connection again, thus going into the connecting state and triggering the `connecting` method. Once the attempt to connect is successful, the `connected` method is triggered thus letting the developer know that the connection is established and is active.

In order to use the ConnectionListeners, you need to add the ConnectionListeners using the `addConnectionListener` method provided by the SDK. You can add multiple listeners as shown below. Just make sure you add listeners with unique IDs.

```typescript theme={null}
class Class_Name  with ConnectionListener {

  __CometChat.addConnctionListener("listenerId", this);
  
  @override
  void onConnected() {
    __ TODO: implement onConnected
  }

  @override
  void onConnecting() {
    __ TODO: implement onConnecting
  }

  @override
  void onDisconnected() {
    __ TODO: implement onDisconnected
  }

  @override
  void onFeatureThrottled() {
    __ TODO: implement onFeatureThrottled
  }

}
```

You can also get the current connection status by using `getConnectionStatus` property provided by CometChat SDK

```javascript theme={null}
String connectionStatus = CometChat.getConnectionStatus();
```

The above method will return either of the below 3 values:

1. `CometChatWSState.connected` (connected);
2. `CometChatWSState.connecting`(connecting)
3. `CometChatWSState.disconnected`(disconnected)
4. `CometChatWSState.featureThrottled`(featureThrottled)
