pure-component-to-class v1.0.2

Pure Component To class

A react codemod to transform stateless/pure/functional components to class components.

Based on:

• react-pure-to-class
• js-transforms

Usage:

npm install pure-component-to-class
npm install -g jscodeshift

// Run using IDE command or via CLI
jscodeshift -t node_modules/pure-component-to-class/pure-component-to-class.js components/TestComponent.jsx

Examples:

Before:

export default ({foo, bar}) => (
  <div>{foo}</div>
)

let Foo = () => <div>foo</div>;

let FooFunc = function (){
  return <div>foo</div>;
};

let FooUsingProps = (props) => {
  const {
    item
  } = props;

  return <li>{item}{props.item2}</li>;
};

let FooUsingPropsWithDifferentName = (propsName) => {
  const {
    item
  } = propsName;

  return <li>{item}{propsName.item2}</li>;
};

After:

export default class extends React.Component {
  render() {
    const {foo, bar} = this.props;
    return <div>{foo}</div>;
  }
}

class Foo extends React.Component {
  render() {
    return <div>foo</div>;
  }
}

class FooFunc extends React.Component {
  render() {
    return <div>foo</div>;
  }
}

class FooUsingProps extends React.Component {
  render() {
    const {
      item
    } = this.props;

    return <li>{item}{this.props.item2}</li>;
  }
}

class FooUsingPropsWithDifferentName extends React.Component {
  render() {
    const propsName = this.props;
    const {
      item
    } = propsName;

    return <li>{item}{propsName.item2}</li>;
  }
}
