Get configuration file and load entries as environment variables.
require('zv-dotenv')();
The above code loads configurations specified in the .env file in the application's root directory.
Use the above code as soon as possible (topmost part) in the main (e.g. index.js or app.js) script.
To load configurations from a custom file, specify its absolute path as an argument, e.g.
require('zv-dotenv')(PATH_TO_CUSTOM_CONFIG_FILE);
Configurations will now be loaded as part of the application's environment variables process.env. To access configurations, e.g.
- .env
DATABASE_USER=user
DATABASE_PASSWORD=password
console.log(process.env.DATABASE_USER, process.env.DATABASE_PASSWORD);
// outputs user password
