envdotyml

Load environment variables from a .env.yml file

Usage

Install envdotyml by running:

yarn add envdotyml

Then, at the top of a file that will be executed before you access any environment variables, add:

import 'envdotyml/set.js'

Alternatively, for more control over when environment variables are set:

import {parse, set} from 'envdotyml'

async function run() {
  // Reads environment variables and mutates `process.env`
  await set()

  // Returns the environment variables without mutating `process.env`
  const vars = await parse()
}

run()

The .env.yml is expected to be an associative array:

STRING: Hello World!
MULTILINE_STRING: |
  foo
  bar
  baz
ARRAY:
  - One
  - Two
  - Three
OBJECT:
  key: value

Strings are left as is. More complex values are converted to JSON strings.

If .env.yml does not exist, parse will return an empty object, and set will do nothing.
