Package Exports

babel-eslint
babel-eslint/package.json

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (babel-eslint) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

babel-eslint

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.

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

Known Issues

no-unused-vars/no-undef with Flow declarations (declare module A {}) #132

Modules/strict mode

no-unused-vars: [2, {vars: local}] #136

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.
