What is dotenv-cli?

The dotenv-cli package is a command-line interface tool that allows you to load environment variables from a .env file into your shell environment. This is particularly useful for managing environment variables in development and testing environments.

What are dotenv-cli's main functionalities?

Load environment variables from a .env file

This feature allows you to load environment variables from a specified .env file and run a command with those variables. In this example, the environment variables from the .env file are loaded and then the Node.js application (app.js) is executed with those variables.

dotenv -e .env -- node app.js

Specify multiple .env files

This feature allows you to load environment variables from multiple .env files. The variables from the files are merged, with the latter files overriding the former ones if there are conflicts. In this example, variables from both .env and .env.local are loaded before running the Node.js application.

dotenv -e .env -e .env.local -- node app.js

Use different .env files for different environments

This feature allows you to specify different .env files for different environments, such as production, development, or testing. In this example, the environment variables from the .env.production file are loaded before running the Node.js application.

dotenv -e .env.production -- node app.js
