Find the environment variables of a nodejs process in linux

If you have an active nodejs process running on your system, the easiest way to check what environment variables it is using can be done in 2 simple steps.

1. Identify the process id of your nodejs app

pe -ef | grep node

1. Use the PID you found in the above step in the following command

sudo cat /proc/PID/environ | tr \0 \n

The above command spits out a large bunch of key-valye pairs. You can always grep it for the variables you are interested in. e.g.

sudo cat /proc/PID/environ | tr \0 \n | grep NODE_ENV

To check the environment variables from within the code itself, simply log the value of the variable process.env anywhere in your code.
