Currently npm-check-updates does not recognise packages used only by babel.config.js config which sits in the root.

Here's a sample babel.config.js to try:

module.exports = function babelConfig(api) {
  const plugins = [
    '@babel/plugin-proposal-class-properties'
  ]
  return {
    plugins
  }
}

then make sure the @babel/plugin-proposal-class-properties is required among dependencies. When ncu is ran, you should get:

I think it should be technically possible to expand the places where we search for "used" things so that Babel configs are included, what do you think?

That's a great idea, although I'm not sure if it belongs more in ncu or in babel. So far ncu does not work with other dependencies besides npm.
