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

If there is an issue, first check if it can be reproduced with the regular parser and with the latest versions of eslint and babel-eslint.

How does it work?

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.
