node-red-contrib-debug-file 0.1.0

A Debug-style Node-RED node that can also write the selected value to a file.

npm install node-red-contrib-debug-file

node-red-contrib-debug-file

A Debug-style node that can show a selected message value in the Debug sidebar and write that same value to a log file. It has no output, so it can be attached to a flow exactly like the built-in Debug node.

Features

• Debug sidebar and runtime-log output can remain enabled independently.
• The file name is automatically derived from the node name: My debug becomes My debug.log.
• A path can be static, msg, JSONata or an environment variable.
• Append or overwrite; optional newline and automatic directory creation.
• Same encoding set as the built-in Write File node, including set by msg.encoding.
• Serialises objects as JSON and preserves Buffers when encoding is none.

Install

After publication to npm, open Menu → Manage palette → Install, search for node-red-contrib-debug-file, install it, then restart Node-RED if requested.

For a local preview, use Manage palette → Install → upload and select the packed .tgz file.

Notes

This is a new debug file node. Node-RED does not allow an add-on to insert fields into the edit dialog of the built-in debug node safely, so the core node stays untouched.

The filename is sanitised on every platform and defaults to debug.log when the node has no name. For a separate file per logger, give each node a unique name.
