babel-eslint allows you to lint ALL valid Babel code with the fantastic ESLint.

NOTE: Please note that this is experimental and may have numerous bugs. It is however successfuly linting the babel core.

ESLint allows custom parsers. This is great but some of the syntax nodes that Babel supports aren't supported by ESLint. When using this plugin, ESLint is monkeypatched and your code is transformed into code that ESLint can understand. All location info such as line numbers, columns is also retained so you can track down errors with ease.

$ npm install -g eslint babel-eslint

.eslintrc

{
  "parser": "babel-eslint",
  "rules": {
    "strict": 0
  }
}

Check out the ESLint docs for all possible rules.
