Use process.env variable in npm script

Question

I have a node.js app which i'm building/hosting on Heroku. I would like to use the environment variables set on Heroku when building my application. for example in package.json

  "scripts": {
    "postinstall": "build --option="MY_HEROKU_ENVIRONMENT_VARIABLE"
}

is it possible to read those variables when the script is run?

Thanks in advance /Eric

No, this is not possible. What you can do instead is define a Node script to run, and have that script itself use environment variables.

For instance, what if your postinstall target was just node postinstall.js, and then inside of your postinstall.js script you read the process.env.MY_HEROKU_ENVIRONMENT_VARIABLE value?
