React eslint error missing in props validation

I have the next code, eslint throw:

react/prop-types onClickOut; is missing in props validation

react/prop-types children; is missing in props validation

propTypes was defined but eslint does not recognize it.

import React, { Component, PropTypes } from 'react';

class IxClickOut extends Component {
  static propTypes = {
    children: PropTypes.any,
    onClickOut: PropTypes.func,
  };

 componentDidMount() {
    document.getElementById('app')
      .addEventListener('click', this.handleClick);
  }

  componentWillUnmount() {
    document.getElementById('app')
      .removeEventListener('click', this.handleClick);
  }

  handleClick = ({ target }: { target: EventTarget }) => {
    if (!this.containerRef.contains(target)) {
      this.props.onClickOut();
    }
  };

  containerRef: HTMLElement;

  render() {
    const { children, ...rest } = this.props;
    const filteredProps = _.omit(rest, 'onClickOut');

    return (
      <div
        {...filteredProps}
        ref={container => {
          this.containerRef = container;
        }}
      >
        {children}
      </div>
    );
  }
}

export default IxClickOut;

You need to define propTypes as a static getter if you want it inside the class declaration:

static get propTypes() { 
    return { 
        children: PropTypes.any, 
        onClickOut: PropTypes.func 
    }; 
}

If you want to define it as an object, you need to define it outside the class, like this:

IxClickOut.propTypes = {
    children: PropTypes.any,
    onClickOut: PropTypes.func,
};

Also it's better if you import prop types from prop-types, not react, otherwise you'll see warnings in console (as preparation for React 16):

import PropTypes from 'prop-types';

I know this answer is ridiculous, but consider just disabling this rule until the bugs are worked out or you've upgraded your tooling:

/* eslint-disable react/prop-types */ // TODO: upgrade to latest eslint tooling

Or disable project-wide in your eslintrc:

"rules": {
  "react/prop-types": "off"
}

It seems that the problem is in eslint-plugin-react.

It can not correctly detect what props were mentioned in propTypes if you have annotated named objects via destructuring anywhere in the class.

There was similar problem in the past

I ran into this issue over the past couple days. Like Omri Aharon said in their answer above, it is important to add definitions for your prop types similar to:

SomeClass.propTypes = {
    someProp: PropTypes.number,
    onTap: PropTypes.func,
};

Don't forget to add the prop definitions outside of your class. I would place it right below/above my class. If you are not sure what your variable type or suffix is for your PropType (ex: PropTypes.number), refer to this npm reference. To Use PropTypes, you must import the package:

import PropTypes from 'prop-types';

If you get the linting error:someProp is not required, but has no corresponding defaultProps declaration all you have to do is either add .isRequired to the end of your prop definition like so:

SomeClass.propTypes = {
    someProp: PropTypes.number.isRequired,
    onTap: PropTypes.func.isRequired,
};

OR add default prop values like so:

SomeClass.defaultProps = {
    someProp: 1
};

If you are anything like me, unexperienced or unfamiliar with reactjs, you may also get this error: Must use destructuring props assignment. To fix this error, define your props before they are used. For example:

const { someProp } = this.props;
