Prevent usage of deprecated methods (react/no-deprecated)

Several methods are deprecated between React versions. This rule will warn you if you try to use a deprecated method. Use the shared settings to specify the React version.

Rule Details

The following patterns are considered warnings:

React.render(<MyComponent />, root);

React.unmountComponentAtNode(root);

React.findDOMNode(this.refs.foo);

React.renderToString(<MyComponent />);

React.renderToStaticMarkup(<MyComponent />);

React.createClass({ /* Class object */ });

const propTypes = {
  foo: PropTypes.bar,
};

//Any factories under React.DOM
React.DOM.div();

import React, { PropTypes } from 'react';

class Foo extends React.Component {
  componentWillMount() { }
  componentWillReceiveProps() { }
  componentWillUpdate() { }
  // ...
}

class Foo extends React.PureComponent {
  componentWillMount() { }
  componentWillReceiveProps() { }
  componentWillUpdate() { }
  // ...
}

var Foo = createReactClass({
  componentWillMount: function() {},
  componentWillReceiveProps: function() {},
  componentWillUpdate: function() {},
  // ...
})

The following patterns are not considered warnings:

ReactDOM.render(<MyComponent />, root);

// When [1, {"react": "0.13.0"}]
ReactDOM.findDOMNode(this.refs.foo);

import { PropTypes } from 'prop-types';

class Foo {
  componentWillMount() { }
  componentWillReceiveProps() { }
  componentWillUpdate() { }
}
