--env-file=.env

Native Support for .env: Starting from Node.js v20.6.0, Node.js supports .env files for configuring environment variables.

Your configuration file should follow the INI file format, with each line containing a key-value pair for an environment variable. To initialize your Node.js application with predefined configurations, use the following CLI command:

node --env-file=.env index.js
