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
The SocketIO DAT is built with socket.io's C++ Client API v1.6.1. Works with with socket.io v2.x servers; socket.io v3 currently not supported.
Parameters - Connect Page
active - When enabled, the SocketIO DAT is actively listening for events from the server, and can also emit events.
url - The URL of the socket.io server.
Verify Certificate (TLS)
verifycert - Enables TLS (transport layer security) certificate verification.
delay - The delay in milliseconds between reconnection attempts.
Parameters - Received Messages Page
callbacks - The Callbacks DAT will execute once for each message coming in.
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.
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 - The DAT is limited to 100 messages by default but with Clamp Output, this can be set to anything including unlimited.
maxlines - Limits the number of messages, older messages are removed from the list first.
clear - Deletes all lines except the heading. To clear with a python script
bytes - Outputs the raw bytes of the message in a separate column.
