This files and folders package contains nodes to perform common file system related tasks like triggering a flow when a new file arrives or list the files in a specific folder.
- The
folder capturenode watches a directory for file creation and update events. - The
folder listingnode lists the files present in a user specified folder. - The
file operationsnode can copy, move and delete files. - The
folder operationsnode allows user specified folders to be created or removed.
Use the Manage Palette option from the Node-RED-menu, or run the following command in your Node-RED user directory - typically ~/.node-red
npm install @objectif-lune/node-red-contrib-files-and-folders
Use the folder capture node as the trigger (input) for file based flows. The node returns information about the file path, basename, size and file extension of any matched file and triggers the flow one file at a time. The node does NOT read the actual file data, for this you should utilize the read file node or pass the path to OL Connect nodes like data mapping, document mapping, file store upload for further processing on the OL Connect Server. However to its benefit the node waits for write operations to finish before triggering the flow.
The folder listing node allows for the filtering of file names using a regular expression or star-based file masks such as *.xml. It also, if requested, will list files in sub folders.
With the file operations node it is possible to define both source and target files. The node has the added advantage of knowing when a file is being used by another process and will terminate the operation if this is the case.
Take CARE when using the folder operations node. It permanently deletes content. Time has been taken to ensure that in case of a user input error the node protects as many essential system and user folders as is humanly possible. This is for both Windows and Linux OS.
This node is part of the OL Connect Automate stack. It is intended for use by current users of OL Connect who want to experiment with automating server operations through Node-RED. The OL Connect Automate stack is a technology preview.
At this early stage, the OL Connect Automate stack is not supported through the OL Care program. Feel free to visit the OL Connect Automate stack forum to post questions, comments and suggestions.
