I am trying to get the active node-RED port in a function node. I read a lot of topics about this, but in my case this doesn't seem to work.

In my settings file, it looks like this:

When I make a statement like this in a function node,

`let port_nodered = RED.settings.uiPort;`

I get this report:

You do not have access to `RED.settings` in a function node.

You could access `env.get('PORT')` in a function

So assuming you wanted port `2828`, then you could either ...

- set `PORT` as an environment variable before launching node-red (preferred / more portable)  
OR
- in the settings file, **above** `module.exports = {`, put `process.env.PORT = 2828`
