The log node

Log incoming data to a file in json format (line by line).

That means, every incoming data-item will be converted to a json string and then appended as a new line to the given file.

The node tries to ensure, that all parent directories for the specified file exist, trying to create them, if necessary.

Note: Only single data_points will be written to the file. If the node is fed data_batch items, they will be unbatched to single data_points first.

Example

|log('topics.txt') 

Parameters

Parameter	Description	Default
[node] file( string )	valid writeable or creatable filepath
