ngDirective - note I haven't exactly dove deep into directives, so I'm sure there are other forms this doesn't account for (e.g. only having the link method?)

ngDirective.js

import ngInject from './ngInject'

export default function ngDirective(directive) {
  let func = function(...injectedArgs) {
    let link = (...directiveArgs) => new directive(...injectedArgs, ...directiveArgs)
    return {...directive.ddo(), link}
  }

  func.$inject = ngInject(directive).$inject

  return func
}

usage.js

class InspectionCardDirective {
  static ngInject() {
    return ['fooService']
  }
  static ddo() {
    return {
      retrict: 'E',
      templateUrl: 'some/path.html',
      scope: {
        inspection: '=inspection'
      }
    }
  }
  constructor(fooService, scope, element, attrs) {
    // my args are:
    // injected args from ngInject
    // followed by args for the link function (scope, element, attrs, ...etc)
  }
}

// then when registering:
.directive('inspectionCard', ngDirective(InspectionCardDirective))
