This repo contains different branches. Each branch shows an alternative to loading env variables using dotenv. Not all branches have a working version, and that's done on purpose.
Please checkout each branch and refer to the README.md for details.
To run each app, use npm start
All examples are executed using babel-node@5.8.23, dotenv@1.2.0, and iojs@2.2.1.
This branch uses babel-node to execute ES6 code. It loads .env by importing dotenv/config.
This app works. Output:

↪ npm start
> dotenv-es6@0.0.0 start /Users/richardkaufman/Dropbox/home/code/dotenv-es6
> babel-node index.js
A message has been left for you:
hello world!
Why and how does this version work? The first line in our code is: import {} from 'dotenv/config' This is pretty much a hack to make dotenv work as expected. When node imports the module, our module gets executed. If we take a look at the code for dotenv/config we see a self-executing anonymous function. So, in the process of importing it, it gets executed and our env vars get loaded.
Please read about more importing modules in the branch import-dotenv-then-config
