env-var

How to use it

{
  "scripts": {
    "hi": "env-var echo {{npm_package_config_hi}}"
  },
  "config": {
    "hi": "HELLO"
  }
}

Works on all platforms (tested on macOS and Windows):

% npm run hi
HELLO

Tips

• Use npm run env to see which environment variables are available on your system.

Inspiration

Inspired by cross-var by Elijah Manor. Differences:

• A different syntax for interpolation.
• Interpolation is implemented differently.
• No dependencies.
