dotenv does not load when path has variable-CodePudding

I am trying to use dotenv to manage configurations for different environment. At the moment, I only have development environment. To test dotenv library, I have .env and .env.development files in the root folder.

In .env, I have

PORT=5001

In .env.development, I have

PORT=5002

In index.js, if I have require('dotenv').config(), .env file is loaded and I can see process.env.PORT is 5001.

If I have require('dotenv').config({path: '.env.' process.env.NODE_ENV}), and I also have NODE_ENV=development node index.js, then .env.development is not loaded.

However, if I have require('dotenv').config({path: '.env.development'}), .env.development file is loaded correctly.

Can I please get some help? Thank you

Well, you can access process.env variables AFTER dotenv package is executed.

So, when you pass a .env variable to it's config, it's still not available for the server.

It is possible. I tried in my local following this post and everything worked as expected.
