Why I Built a Lightweight Alternative to dotenv

The Problem

dotenv is the standard for loading .env files in Node.js — but it has more features than most projects need, and the dependency tree keeps growing.

I wanted something minimal: zero dependencies, tiny API, and fast.

env-fast is a zero-dependency .env loader with a simple API:

const env = require('env-fast');
const result = env.load();
console.log(result); // { loaded: true, path: '.env', variables: 12 }

npm install env-fast

// .env
PORT=3000
DATABASE_URL=postgres://localhost/mydb

// index.js
const env = require('env-fast');
env.load();
console.log(process.env.PORT); // 3000
