Prevent React to be incorrectly marked as unused (react/jsx-uses-react)

JSX expands to a call to React.createElement, a file which includes React but only uses JSX should consider the React variable as used.

If you are using the @jsx pragma this rule will mark the designated variable and not the React one.

This rule has no effect if the no-unused-vars rule is not enabled.

You can use the shared settings to specify a custom pragma.

Rule Details

Examples of incorrect code for this rule:

var React = require('react');

// nothing to do with React

/** @jsx Foo */
var React = require('react');

var Hello = <div>Hello {this.props.name}</div>;

Examples of correct code for this rule:

var React = require('react');

var Hello = <div>Hello {this.props.name}</div>;

/** @jsx Foo */
var Foo = require('foo');

var Hello = <div>Hello {this.props.name}</div>;

When Not To Use It

If you are not using JSX, if React is declared as global variable, or if you do not use the no-unused-vars rule.

If you are using the new JSX transform from React 17, you should disable this rule by extending react/jsx-runtime in your eslint config.
