### Events

The Node Redis client class is an Nodejs EventEmitter and it emits an event each time the network status changes:

| Event name | Scenes | Parameters |
|--------------|-------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------|
| connect | The client is initiating a connection to the server. | _undefined_ |
| ready | The client successfully initiated the connection to the server. | _undefined_ |
| end | The client disconnected the connection to the server via `.quit()` or `.disconnect()`. | _undefined_ |
| error | When a network error has occurred, such as unable to connect to the server or the connection closed unexpectedly. | The error object, such as `SocketClosedUnexpectedlyError: Socket closed unexpectedly` or `Error: connect ECONNREFUSED [IP]:[PORT]` |
| reconnecting | The client is trying to reconnect to the server. | _undefined_ |

The client will not emit any other events beyond those listed above.
