Good way to save all your keys and secrets for making sure that your specific keys won’t be committed to the public git repository.

npm install dotenv --save

Create .env file and save all your key values in that file.

DATABASE_ENDPOINT=east-2.rds.amazonaws.com
DATABASE_USERNAME=admin
DATABASE_PASSWORD=ry436gdg
DATABASE_PORT=666
DATABASE_NAME=database_name

You can directly access the environment variables in your function or class in JS and TS. It automatically gets invoked with the node process.

Access it via

console.log(“Your environment key” , process.env.DATABASE_ENDPOINT)

If you get process.env as undefined value, you should do the following

const dotEnv = require("dotenv");
// Initialize
dotEnv.config();

console.log(process.env.DATABASE_USERNAME);

Save in “.env” file Set the production username, password and other parameters which you don’t want to commit to git.
