Using Terminal to run Node.js command

[Bala]

Hello,

I am having an issue with a 3rd party node in Node-Red and there's a resolution for it on the github forum but I do not know how to implement it. I will need to run the following command: export NODE_OPTIONS=--openssl-legacy-provider but am not sure how and where to run it from. I usually run such commands from the terminal if Node-Red is installed locally on PC but can't seem to figure out how to do it here. Any help on this is appreciated.

Thanks,

Bala

Hi @Bala ,

Since there is no terminal within Node-RED, you'd have to do this over SSH. You could also build the node offline, include the necessary configuration, package it as tar.gz, and then install the package manually in Node-RED.

Which pallet are you trying to work with? Is this on a physical or virtual CORE?

Hi @Sgilk ,

I am working with the opc-da-in pallette (https://flows.nodered.org/node/node-red-contrib-opc-da). This is on physical core X3. Any documentation on how it can be done over SSH? My knowledge is limited when it comes to building node offline.

On a physical CORE, you'll need to request an ssh user assertion. This would not be valid for a production solution and only for development purposes.

See this How-To for more info.

If exporting the environment variable is required and you don't have ssh access, I think your best bet will be building a custom Node-RED snap.
