Spliting Data | supOS CE

Example

We have a single message containing multiple furnace readings, and we need to split them into individual messages for further processing.

{
  "furnace": {
    "temp": 86,
    "humidity": 64,
    "pressure": 80
  }
}

In this example, we use the split node to break one message into multiple smaller messages.

Parameter	Description
Name	Optional label for the node to help identify it in the flow.
Split the	The property of the message to split, usually `msg.payload`, but can be any property such as `msg.payload.data`.
String / Buffer - Split using	For string or buffer payloads, specifies how to split: • string: Use a specific string or regular expression pattern to split the message. • buffer: Defines chunk size by which the message is split. • Fixed length of: Split the string according to the set length. • Leave empty to return the tring unsplit.
Handle as a stream of messages	When checked, the node will process incoming data as a continuous stream, emitting split messages as data arrives, rather than waiting for the full payload.
Array - Split using	Fixed length of N: Splits the array into multiple messages with N elements each.
Object - Send a message for each key/value pair	The value of each key/value pair will be returned as payload.
Copy key to `msg.payload`	If checked, the original key will be returned as `msg.payload` of the split messages.
