How to add support for decorators in node.js?

Question

JavaScript

The question is relevant in the context of Babel. The next goal is to connect to the MobX node and use the ESNext decorators (@observer and others like them) (which, as far as I remember, are still only in Stage 2). I run the node with the --harmony flag and write in ES6 right away, without transpiling. Now I need to include babel and its babel-plugin-syntax-decorators and babel-plugin-transform-decorators-legacy plugins. I don't understand what to do next at point-blank range - now to run babel, do you need babel-runtime or babel-polyfill? Given that I need it to compile decorators to ES6? Is this even possible?

$ node -v
v7.5.0

"devDependencies": {
    "babel-cli": "latest",
    "babel-core": "latest",
    "babel-plugin-syntax-decorators": "latest",
    "babel-plugin-transform-decorators-legacy": "latest",
    "babel-plugin-transform-object-rest-spread": "latest",
    "babel-preset-stage-2": "latest",
    "babel-register": "latest",
    "gulp": "latest",
    "gulp-babel": "latest",
    "redis-cli": "latest",
  }

Specify plugins in .babelrc file and run via babel-node
