Prevent variables used in JSX to be incorrectly marked as unused (react/jsx-uses-vars)

Since 0.17.0 the ESLint no-unused-vars rule does not detect variables used in JSX (see details). This rule will find variables used in JSX and mark them as used.

This rule only has an effect when the no-unused-vars rule is enabled.

Rule Details

The following patterns are considered warnings:

var Hello = require('./Hello');

The following patterns are not considered warnings:

var Hello = require('./Hello');

<Hello name="John" />;

When Not To Use It

If you are not using JSX or if you do not use the no-unused-vars rule then you can disable this rule.
