Exception for space-before-keywords?

[olalonde]

Writing a React/redux app, I am occasionally declaring anonymous classes inside function calls:

export default connect()(class extends Component {
  // React component class definition
});

which gives this error: Missing space before keyword "class". (space-before-keywords).

If I put a space there:

export default connect()( class extends Component {
  // React component class definition
});

It fails another rule: There should be no spaces inside this paren. (space-in-parens).

Was wondering if that was an unintended effect of the space-before-keywords or if everything is working as expected.

I think the styleguide should specify to avoid anonymous classes. Especially in case of React where the class name is used as a "display name".

I agree one should avoid anonymous classes - but also, aggressive inlining. I'd recommend defining the class first, and then exporting the connected value in a second line.

Specifically, I think this is a bug with the space-before-keywords linter rule, that perhaps should be filed to eslint directly.
