I wanted to use moment in a function node. I stumbled upon this issue which appears rather old.
I tried using the tip to add the moments to the functionGlobalContext but did not work. I did not get the error during NR startup that it does not find moments, but global.get("moment") did not return anything.
Now, I am using the function-npm node where I can use require and it works:
var moment = require('moment');
msg.payload = moment().format('MMMM Do YYYY, h:mm:ss a'); // April 27th 2020, 6:08:20 pm
Is this still the recommended method, or did I missed some other and supported option?
The recommended method is still what it says in the docs - https://nodered.org/docs/user-guide/writing-functions#loading-additional-modules
Can you share exactly what you added to your
This is what it says exactly:
I know you mentioned before that moment could be installed in the incorrect directory. I am running NR on Windows now, and it is installed here: C:\Users\xxxxx\AppData\Roaming\npm\node_modules\node-red\node_modules\moment.
You should run the
npm install moment command in the same directory as your
I have done that now:
C:\Users\xxxxxx\AppData\Roaming\npm\node_modules\node-red>npm install moment

It is still not working, moment is undefined in the function node. Should I see something in the log when I start node-red? I mean I am not seeing any info or warning that the moment is being loaded or failed to load.
That suggests you have edited the wrong settings file. Node-RED logs the full path to the settings file it is using when it starts. Make sure you have the right one.
Sorry for all this, of course I was looking in a wrong directory.
I have re-installed
npm install moment in
c:\users\xxxxx\.node-red where my actual settings.js file as and now everything works. The code in my first comment works in a regular function node.
