React v16のPropTypesでハマった

More than 1 year has passed since last update.

Reactのバージョンを上げた際に、PropTypesはReactにあるものだと思ってハマってしまった。

React 15.5からPropTypesはprop-typesとしてライブラリが切り離されているっぽい。
https://github.com/reactjs/react-codemod#react-proptypes-to-prop-types

というわけで

Reactのバージョン

package.json
"react": "^16.8.6"

prop-typesをインストール

私は、yarnを使っているので...

yarn
$ yarn add prop-types 

npm 
$ npm install --save prop-types
Hoge.jsx
// 修正前
Hoge.propTypes = {
  hoge: React.PropTypes.object.isRequired
}

// 修正後
// ファイルの上部
import PropTypes from 'prop-types';
.
.
.
Hoge.propTypes = {
  hoge: PropTypes.object.isRequired
}

Reactから切り離されたので Reactからではなく、インポートしたPropTypesから定義すれば良い
