@cch137/env

The @cch137/env package provides a simple utility function to load environment variables from a .env file or multiple .env files into Node.js process.env. This package is inspired by the functionality of the "dotenv" npm package.

Installation

npm install @cch137/env

Usage

The @cch137/env package exposes a single function env that can load environment variables from one or more .env files.

Example

const env = require("@cch137/env");

// Load environment variables from a single .env file
env(".env");

// Load environment variables from multiple .env files
env([".env", ".env.local"]);

Functionality

The env function accepts either a single string filename or an array of filenames. It reads each file, parses key-value pairs, and sets them as environment variables in process.env.

• File Format: Supports parsing of .env files with key-value pairs (e.g., KEY=VALUE).
• Value Parsing: Handles quoted values (", ', `), supports escape sequences (\n, \r), and removes surrounding quotes.
• Comments: Ignores lines starting with #.
• Environment Setup: Updates process.env with parsed key-value pairs.
