How to update NODE.js, NPM and NodeRed?

[JakubSzlaur]

Hello everyone,
I am trying to update NODE.js, NPM and NodeRed on my UNIPI NEURON S103-G.

I have found this document on how to do it. But it looks outdated - is it still valid to use this command from the document?

bash <(curl -sL https://raw.githubusercontent.com/node-red/raspbiandebpackage/master/resources/update-nodejs-and-nodered)

Thank you in advance! :)
