What is dotenv-safe?

The dotenv-safe npm package is used to load environment variables from a .env file into process.env, ensuring that all necessary environment variables are defined and preventing the application from running if any required variables are missing. It extends the functionality of the dotenv package by adding a layer of safety and validation.

What are dotenv-safe's main functionalities?

Load Environment Variables

This feature loads environment variables from a .env file into process.env, ensuring that all required variables are defined. If any required variables are missing, it will throw an error and prevent the application from running.

require('dotenv-safe').config();

Validation of Required Variables

This feature allows you to specify an example .env file that lists all required environment variables. The package will validate that all variables in the example file are present in the actual .env file, ensuring that no required variables are missing.

require('dotenv-safe').config({ example: './.env.example' });

Custom Path for .env File

This feature allows you to specify custom paths for both the .env file and the example file. This is useful if your environment files are located in a different directory.

require('dotenv-safe').config({ path: './config/.env', example: './config/.env.example' });
