Discussion on: Environment variables in Node.js. The Right way!

why your script start prodouction did not load dotenv?

dotenv is a dev dependency. In production, keys are stored on the server which can be accessed by node without using dotenv

can you give me little example how storing keys on production? thank you

For example, heroku has a option in app settings to enter environment variable.

The Suhu • Jan 10 '20

yes, in heroku there is an option to store that. but how if we use own server?

Vikas Raj • Jan 10 '20 • Edited

Like this

// keys.js ======
module.exports = {
    PORT: process.env.PORT,
    WHO_AM_I: process.env.WHO_AM_I,
};

ok, thank you.

But, still we're using 'process.env', which uses to 'dotenv' package in production?

In production I didn't use .env, I store all credentials on host environment or if I use docker, I store it in docker secrets.

Cool, thanks!

Yes thats right that we store keys on server.
But what about the dotenv package we imported into file and written as process.end.VAR_NAME ? Wont it require to use dotenv package?
