SocketIO DAT


The SocketIO DAT connects to a Socket.IO server at the specified URL.

Additional headers can be specified via the first input of the SocketIO DAT. This input should be in a table format with two columns, structured as name/value pairs.

The SocketIO DAT listens to specific events that the server emits. These events are added as listeners via the second input, structured as a single column of event names. Then, when the server emits these events the onReceiveEvent callback will be triggered.

The SocketIO DAT can also emit events to the server. This is done using the python emit method.

The SocketIO DAT is built with's C++ Client API v1.6.1.

URL url - The URL of the server.  

Verify Certificate (TLS) verifycert - Enables TLS (transport layer security) certificate verification.  

Reconnect Delay delay - The delay in milliseconds between reconnection attempts.  

Parameters - Received Messages Page

Callbacks DAT callbacks - The Callbacks DAT will execute once for each message coming in.  

Execute from executeloc - - Determines the location the script is run from.

  • Current Node current - The script is executed from the current node location.
  • Callbacks DAT callbacks - The script is executed from the location of the DAT specified in the Callbacks DAT parameter.
  • Specified Operator op - The script is executed from the operator specified in the From Operator parameter below.

From Operator fromop - The operator whose state change will trigger the DAT to execute its script when Execute from is set to Specified Operator. This operator is also the path that the script will be executed from if the Execute from parameter is set to Specified Operator.  

Clamp Output clamp - The DAT is limited to 100 messages by default but with Clamp Output, this can be set to anything including unlimited.
