How do you set node flags for a npm run-script?

Question

There is a Node.js flag that increases the length of stack traces:

--stack-trace-limit (number of stack frames to capture)
     type: int  default: 10

But I am running my command like this from a package.json:

  "scripts": {
    "unit-test": "jasmine"
  }

This is not an NPM flag, or a Jasmine flag either. It's a flag for the node command.

How do can I set --stack-trace-limit when I npm run unit-test?
