Hello, I have created a flow which is having mongo db node-red-contrib-mongodb2 node .  
So, I have set environment variables in settings.js file as  
process.env.host="127.0.0.1";  
process.env.port = 27017;  
process.env.database="test;

I want to use these environment variables inside mongo db 2 node. How can do that?

Not sure why you have started a new thread.

Like I explained with a link to the docs and a screenshot in the other thread : [Node properties stored in external json file - #11 by Steve-Mcl](https://discourse.nodered.org/t/node-properties-stored-in-external-json-file/47638/11)

Ps, I would not use port and host as they may conflict with node-red. I'd use mongo\_host and mongo\_port
