Read environment variables in Node.js

Question

Is there a way to read environment variables in Node.js code?

Like for example Python\'s os.environ[\'HOME\'].

Answer 1

You can use env package to manage your environment variables per project:

• Create a .env file under the project directory and put all of your variables there.
• Add this line in the top of your application entry file:
  require('dotenv').config();

Done. Now you can access your environment variables with process.env.ENV_NAME.
