Node.js - load .env file from a different location

I have a Node.js application which runs fine with the standard node index.js syntax (relative path...) Then I had the need to run it with the absolute path in node /home/bots/mybot/index.js and it was working great as well.

Now I have the need to add a .env file which is still running great from relative path, but I'm not able to run it from absolute path anymore since it's not reading the .env file! I think it is looking for it in the / path which is not ideal of course.

EDIT: I'm currently using discord.js library which probably is using dotenv or something very similar inside.

Any suggestions?

Taking an assumption in my mind, i.e. you're using dotenv package for the .env

From the Docs (You can specify the custom path to .env)

You may specify a custom path if your file containing environment variables is located elsewhere.

require('dotenv').config({ path: '/full/custom/path/to/your/env/vars' })

Or you may do it using the command line, when calling your index.js

While running node your/absolute/path/index.js

node -r dotenv/config your/absolute/path/index.js dotenv_config_path=/custom/path/to/your/env/vars
