first: npm install dotenv

second: In server side index.js import and configure dotenv: require("dotenv").config();

third: in .env file, write the user name and password with a name for-ex( DB_USER=username DB_PASS=password )

forth: username and password title as ${process.env.DB_USER} and ${process.env.DB_PASS} have to used by replaced on uri codes 'username' .

now check the terminal and database Thank you
