How to extend babel config

[Marcus-Rise]

Problem

Seems to CRA webpack config and babel docs it's impossible to extend babel config without eject

How can I use additional babel plugins, such as @babel/plugin-proposal-decorators?

One of the existing third-part solution

Now I have the only way to extend config - using react-app-rewired and customize-cra:

package.json

...
 "scripts": {
    "dev": "react-app-rewired start",
    "build": "react-app-rewired build",
    "test": "jest",
  },
...

config-overrides.js

const {useBabelRc, override} = require('customize-cra');
module.exports = override(useBabelRc());

.babelrc

{
  "presets": [
    "react-app"
  ],
  "plugins": [
    [
      "@babel/plugin-proposal-decorators",
      {
        "legacy": true
      }
    ],
    "babel-plugin-transform-typescript-metadata",
    "babel-plugin-parameter-decorator"
  ]
}

Why I need it?

I usually use inversify and I want to use decorators like in this example
