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

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
