How to debug ES6 NodeJS with WebStorm?

I am trying to debug a nodejs ES6 server, even though I am using babel, I am getting this warning:

(node:17736) [DEP0062] DeprecationWarning: `node --debug` and `node --debug-brk` are invalid. 
Please use `node --inspect` or `node --inspect-brk` instead.

Process finished with exit code 9

Can someone help me fix this? I saw many questions about this, but they all seem old and are not working for newest versions of nodejs.

This is my configuration:

Since Lena's answer won't work with async code, you will need to install @babel/polyfill and require it in the webstorm debug configuration together with the babel-register

--require @babel/register --require @babel/polyfill

What worked for me:

Using nodemon Added a run/debug NPM configuration that runs this script "dev": "nodemon"

Seems the Node.js version babel-node is using doesn't accept --debug-brk option, and Webstorm can't detect what Node.js version is being used (normally it checks the version of Node.js chosen as Node interpreter: and uses the appropriate options when running).

Please select the Node.js executable instead of babel-node there and use --require @babel/register as Node parameters: in run configuration to get ES6 code compiled on-the-fly:

enter image description here

Of course, you need to make sure to install the corresponding modules and set up the .babelrc accordingly

package.json:

"dependencies": {
  "@babel/cli": "^7.2.3",
  "@babel/core": "^7.4.0",
  "@babel/preset-env": "^7.4.2",
  "@babel/register": "^7.4.0",
...
}

.babelrc:

{
  "presets": [
    [
      "@babel/preset-env"
    ]
  ]
}
