How to access environment variables in NodeJS by adding .env file

In this video we're gonna learn how to add .env file and access environment variables in NodeJS project.

In real world projects we cannot put all our sensitive information like Database credentials, API tokens ..etc. in our code plain hardcoded. So, we use Environment variables for that. We define all our Environment related variables in a separate file: we call it .env file and we have different .env files for different environments.

So, in this video we have simple NodeJS project written with TypeScript and we're gonna add a .env file and put some values there (Port, Environment ..etc.) and access them in the code.
