Node version used in latest release

Hi there.

I'm facing one issue while trying to install opcua node, it keeps telling me its not compatible on my node version as you can see in following attachment:

I wanna know which version of node is used

The error message seems to suggest that your nodejs is below version 15 and is informing you that it needs to 15 or higher for your node

Reading the screenshot it would suggest you need v15 or above.

As for Node-RED, currently, V16 or V18 is the recommended version.

PS: We do not recommend or support odd numbered node releases (i.e. do not install V15)
