javascript: 1.0.0 - Unexpected token = with static properties

With 0.1.0 and 0.1.1, this was fine

export default class Root extends React.Component {
  static propTypes = {
    ...
  }
...

After switching to 1.0.0, eslint complains about Parsing error: Unexpected token =, referring to the=afterpropTypes`.

About this issue

But we are using es7 static properties now, and eslint still complains about it!

Yes, the transform would go in whatever runs babel. You need to add a root "parser": "babel-eslint" as well.

This isn’t the proper venue for this kind of help tho - please feel free to join babel’s slack, or our gitter channel, or freenode on IRC.

That’s because we don’t use es7’s static class methods yet. This is the intended behavior.

I managed to get it working by installing babel-eslint: npm install babel-eslint

Then adding this line to my .eslintrc.js:

module.exports = {
  // the line I added:
  parser: "babel-eslint",
  // the rest of my config here...
};

@ljharb plz mention that we need to add this into .eslintrc

Assigning them outside the class body, yes.
