Passing environment variables to node.js using pm2

Question

I am trying to pass some arguments to my Express application which is run by pm2. There wasn't any hint in their documentation to do so, but apparently it's possible to pass some EV to your node application like SOME_STUFF=xxx pm2 start app.js.

Answer 1

Note - after updating environment variables in your environment, you must do the following:

pm2 restart all --update-env

ask me how I know...

Edit: also look for a .env file in the node source directory...
