package-engines-notifier

warns users about incompatible Node.js versions per engines in package.json

Usage

enginesNotify(options: EnginesNotifierOptions) => Error | null

type EnginesNotifierOptions = {
  pkg: PackageJson
}

• see upstream documentation for PackageJson

• if there is engine trouble, outputs a message using console.error(), and returns an Error

• otherwise, no output, and returns null

Example

const { enginesNotify } = require('package-engines-notifier')

const pkg = require('./package.json')

if (enginesNotify({ pkg })) {
  // uh-oh, the user's engines don't match, stop right here
  return
}

// TODO: what your script does when engines match
